24 Chapter 2 - Quick Start
Chapter 2 - Quick Start
This chapter describes how to quickly get a new user started with RasterMaster ActiveX.
If you do not find the information that you are looking for in this manual, please open a support ticket at http://support.snowbound.com to request a specific sample, for clarification of a method description or to help you find the information they need. We are dedicated to helping our customers succeed and we are constantly enhancing our products based on feedback from customers like you.
Getting Started
This section describes how to get started with RasterMaster ActiveX. To decompress and display images using RasterMaster ActiveX:
1. Double-click the Snowbound Icon in the Toolbox. This places the image control onto the current open form. The control appears small at first.
Note: If the Snowbound custom control is not in the toolbox, see Custom Controls for information on how to add a custom control to the toolbox.
2. Select a handle of the control to enlarge the image control window to the size you want.
3. Set the properties for your specific applications’ needs. You may also set the properties of the control programmatically at run-time.
Setting only one property decompresses and displays the image to the Snowbound image control.
Quickly Getting Started with the Format Conversion Sample
The fastest way to get started is to run the Format Conversion sample that is included with this product. You can find the samples in the following directory C:\Program Files\Snowbound Software\RasterMaster® ActiveX Evaluation\ActiveX\Samples. The Format Conversion sample will convert any supported document type into the file format you request and then display it. For more information, please see Appendix E, Samples Using Visual Basic V6.0 on how to find and run the Format Conversion sample.
The Format Conversion sample uses three routines that are at the heart of RasterMaster:
25 Chapter 2 - Quick Start
1. Image Property - decompresses and displays the image to the current control.
2. SaveFormat Property - saves an image to disk when used with the Save property.
3. Save Property - saves an image by passing in the name of the image to save.
The properties mentioned above are described in detail later in this manual. This manual also covers the following topics:
1. How to read and save multi-page documents. For more information, please see Chapter 6, Saving and Reading Multi-page Images.
2. How to adjust the color, compression and resolution attributes of documents for performance, better quality output, or smaller output.
3. How to extract text and search for text in documents. Please note that Snowbound Software does not yet support OCR (Optical Character Recognition). Therefore, we can only extract text from documents that contain text. You can use RasterMaster in conjunction with OCR tools from other companies if you need to extract text from scanned document images.
We include a lot of code samples to help you get started. These samples are listed in Appendix C, Samples Using Visual Basic V4.0, Appendix D, Samples Using Visual Basic V5.0 and Appendix E, Samples Using Visual Basic V6.0. We have also indexed our documentation and made it searchable to help you find what you need quickly.
If you have any questions please do not hesitate to open a support ticket at http://support.snowbound.com.

30 Chapter 2 - Quick Start
The amount of memory required to view documents varies depending on the size of the documents you are processing and the number of documents you are processing at any one time. The amount of memory needed increases as:
l You go from small index card size images to large blueprint size images (number of pixels increases).
l You go from compressed to uncompressed document formats (lossy compression to raw image data).
l You go from low resolution to high resolution documents (dots per inch / quality increases).
l You go from small index card size images to large blueprint size images (number of pixels increases).
Determining Memory Requirements
The amount of memory required to display a document may be significantly larger than the size of the document that is stored on disk. Just like a road map, the document is folded up and compressed when it is stored. In order to see the document, it must be unfolded (decompressed) and spread out so you can see the whole map. The map takes up much more room when open for viewing. The same is true of online documents. When a document is open, a black and white letter size page at 300 dpi takes roughly 1MB of memory to display and a color page takes 25MB.
Generally, higher quality documents require more memory to process. Snowbound Software does not have a one-size-fits-all recommendation for memory because our customers have such a variety of documents and different tolerances for the level of output quality. However, you can try doubling the memory available to see if that resolves the issue. Keep increasing memory until you stop getting out of memory errors. If you hit a physical or financial limit on memory, then you can do the following:
l Decrease the quality of the images requested by decreasing bits per pixel, the resolution, or the size.
l Decrease the number of documents you have open at any one time.
To calculate the amount of memory required for an image, you will need to know the size of the image in pixels and the number of bits per pixel in the image (black and white=1, grayscale=8, color=24). If you do not know the height or width in pixels, but you do know the size in inches and the dpi (dots per inch) of the image, then you can calculate the size in pixels as (width_in_inches*dots_per_inch) = width_in_pixels.
To calculate the amount of memory (in bytes), multiply the height, width and number of bits per pixel. Then, divide by 8 to convert from bits to bytes. See the following example:
(height_in_pixels * width_in_pixels * bits_per_pixel)/ 8 = image_size_in_bytes
Table 2.2: Memory Requirements Based on Image Size
31 Chapter 2 - Quick Start
Image Size Required Memory 24-bit per pixel, 640 x 480 image 640 * 480 * (24 / 8) = 921600 bytes 1-bit per pixel, 8.5" x 11" image, at 2550 * 3300 * (1 / 8) = 1051875 bytes 300 dpi (2550 pixels by 3300 pixels) 24-bit per pixel, 8.5" x 11" image, at 2550 * 3300 * (24 / 8) = 25245000 bytes (25 300 dpi (2550 pixels by 3300 pixels) megabytes)

Overlay Property
This property sets the path for overlay files for PT:OCA images. The library searches this path for overlay files required by PT:OCA images. It toggles between the two ways in which the overlay file is decompressed if a NULL parameter is passed.
For example, there is a check overlay image file (the file has a check image on a larger white background). If a null parameter is entered, toggling occurs, which lets you retrieve just the check image itself without the extraneous white space. This way, you just get the check image. Calling this method again retrieves the original image.
Note: Only used with certain overlay files.
Syntax
Setting% = [form.]Snowbound1.Overlay

Chapter 4 - AFP Font Mapping Property
This chapter describes the snbd_map.fnt file and the property used for AFP font mapping. The chapter contains the following topics:
AFP Font Mapping
Format of Font Mapping Data
FontMapPath Property
AFP Font Mapping
AFP files can use specific fonts to achieve a particular look. If you find that the fidelity of the output for your AFP documents is lacking, particularly in regards to text size and spacing or barcodes, then you can customize RasterMaster ActiveX to use particular fonts when processing your AFP files. RasterMaster ActiveX is easy to customize to improve the look of your AFP documents. Snowbound Software allows you to map the fonts in your AFP/MODCA document to fonts on your system using a mapping file named snbd_map.fnt. The snbd_ map.fnt file is custom crafted to specify the fonts used in your AFP files and on your system. If you provide a representative sample AFP document to Snowbound Software by entering a support issue at http://support.snowbound.com , we will provide you with a custom snbd_ map.fnt file usually in a few business days that will improve the display and print quality of your AFP documents.
RasterMaster ActiveX automatically loads the snbd_map.fnt file if it is found in one of the following directories:
l The directory into which images are being read. For example: C:\\AFP\\fontmap
l The directory where your application exists as long as you are not changing directories with a dialog box
The following property allows you to set font mapping:
The FontMapPath property sets the path of the font mapping file. See the FontMapPath Property for more information.
Format of Font Mapping Data
Any AFP font name can now be mapped to the following:
l face name
l point size
l bold attributes
l italic attributes
150 Chapter 4 - AFP Font Mapping Property
The snbd_map.fnt file is a simple ASCII text file. Each entry is ended with a carriage return line feed. The following are two sample entries:
C0BC25I3,Courier,10,0,0
C0CGT12S,Times New Roman,14,0,1
Table 4.1: Description of the sample entry in the snbd_map.fnt file
Variable Description Font resource name in the AFP C0BC25I3 file. Courier New face name to map to. New size in points or 1/72 of an 10 inch. 0 Bold attribute, 0 - off , 1 - on. 0 Italic attribute 0 - off, 1 - on.

Gray Scale Images
If a color or gray scale image is being printed to a 1-bit or bi-level printer such as HP- LASERJET type printers, the image is dithered or reduced to 1-bit per pixel automatically.
The capabilities of the printer are detected by the Snowbound libraries to tell if the image must be dithered. The technique employed is the Stucky error diffusion. This simulates a gray scale by the placement of dots. The higher the resolution of the printer, the better the effect.
PrintFast
PrintFast is used with Postscript printers. It does a nice job of scaling, and dithering images. The whole image, in its original size, is sent to the printer with no pre-processing.
Note: For more complex printers such as POSTSCRIPT, PrintFast prints large images much faster, but is not guaranteed to work with all printers.
See PrintFast Property for more information on this property.
PrintImage for Printing Bitmaps
Printing bitmaps under Windows is very difficult due to printer drivers not supporting DIB’s, bitmap sizes greater than 64k, scaling, and color reduction.
Due to these problems, it is best to the use the PrintImage property. This causes the library to scale, crop, reduce, and band the image to be able to print on any printer.
Printing Large Documents
Printing large documents, such as documents approaching or exceeding 100 pages, or documents set to a resolution of 300 DPI or above, requires additional memory resources. These additional resource requirements can affect the performance of both servers and clients.
Servers
Depending on the current Java Virtual Machine memory configuration for the Imaging server, the need for additional resources may cause an out of memory error. Increasing the Java Virtual Machine maximum heap size to the Imaging server during start up can help avoid memory errors. Specify the minimum and maximum heap size by passing the parameter -Xms and -Xmx to the Imaging server during start up, where the amount of memory is in megabytes or gigabytes you want to allocate to the Imaging server.
Clients
Each of the different browsers handles the increased resource demands uniquely. In some cases, when printing documents that require additional resources, the document may print with blank pages, fail to respond, or require the browser or computer to be restarted.
155 Chapter 5 - Properties by Category
Solution
A workaround for this problem may be to download the document locally and then print it. If the document does not have any annotations or the document is to be printed without annotations, the original document can be downloaded and printed. However, if a document is to be printed with annotations, a TIFF version of the document can be downloaded and printed.
Scanning Properties
The SnowBound control supports all TWAIN scanners. TWAIN is a driver specification for input devices devised by an independent group.
The proper TWAIN and scanner (or input device) driver must be installed. You should have a TWAIN directory in your \WINDOWS directory if installed.
Normally, it is not necessary to do anything but set ScanAcquire to 1 when scanning a single image. See Custom Control Properties for detailed property information.
Table 5.8: Scanning Properties
ScanAcquire ScanBits ScanBottom ScanCap ScanCapGet ScanCapValue ScanCloseFeeder ScanDuplex ScanFast ScanHres ScanLeft ScanOpenSource ScanPages ScanRight ScanSetup ScanShowUI ScanTop ScanVres
Steps for Scanning
1. Select TWAIN source using ScanOpenSource if more than one device is installed.
2. Set scanning parameters using ScanSetup to set up scanner driver.
3. Use ScanCapValue to set the value of the TWAIN scanning ability. To verify the value, use ScanGetCaps or ScanCaps.
4. Select the paper source using ScanAcquireFeeder (document feeder - single or multiple pages), ScanAcquire (scan single image from flatbed area). You can either scan from the flatbed area of the scanner or the document feeder. Typically, the scanner looks at the document feeder first. If there is no paper in the document feeder, it scans from the flatbed area.
5. Determine if you want to see the TWAIN user interface during scanning, using Showui.
6. Scan multi-page documents from the document feeder using ScanPages.
7. Select the scanning capabilities.

157 Chapter 6 - Saving and Reading Multi-page Images
Chapter 6 - Saving and Reading Multi-page Images
This chapter describes how to decompress, determine page counts, save, and convert multi- page images in the RasterMaster ActiveX Imaging SDK.
Multi-page Images
All Snowbound libraries decompress a single page at a time. This section describes the multi- page formats and how to decompress, determine page count, and save multi-page images.
Supported Multi-page Formats
The RasterMaster ActiveX Imaging SDK currently supports the following multi-page formats:
l TIFF
l DCX
l GIF
l MO:DCA/IOCA
l PDF
l MS Word - Reading
l MS Excel - Reading
l PowerPoint - Reading
l RTF - Reading
Decompressing a Multi-page Image
Each page must be decompressed then saved separately. In other words, a decompress then save must be performed for each page.
The first page is decompressed with the Image property. See Image Property for more information.
To decompress any other page, use the Page property to set the current page number to decompress. See Page Property for more information.
Determining Multi-page Page Count
You can keep decompressing pages until a PAGE NOT FOUND or -11 error is returned from the decompress function or method, or you can query the number of pages with the Pages
158 Chapter 6 - Saving and Reading Multi-page Images
property. See Pages Property for more information.
Saving Multi-page File Formats
When saving to a multi-page file format, keep in mind that all RasterMaster products append or add new pages to an image file if the file already exists. If you do not want to keep saving to the same file, you must first delete the page or save each page to a unique file name. See the Multi- page sample Multi-page for more information.
Multi-page Format Properties
Table 6.1: Supported Multi-page Properties
Properties Description Detects the number of pages in a file. See Pages Property Pages for more information. Image Reads pages. See Image Property for more information. Specify the specific page to import. See Page Property for Page more informaton about this property. Saves multi-page images.
For an existing file, new pages are appended.
For new files, new pages with the specified name are Save created as necessary.
Note: Use a unique filename when saving to multi-page formats; otherwise, images are automatically appended to any file with the same name.
159 Chapter 7 - File Format Conversion
Chapter 7 - File Format Conversion
This chapter describes how to convert an image to a different file format.
Converting File Formats
The RasterMaster products support over 100 file formats. Many formats such as TIFF are very broad in the internal support of compression and bit depths. Not all formats can support all bit depths.
All RasterMaster ActiveX products import and convert file formats to Snowbound’s internal formats at decompress time. The format is a simple uncompressed DIB format stored in memory. This format is decompressed or imported and can be saved out to any supported format. See Appendix A, Supported File Formats for a complete list of supported file formats.
Automatically Detecting File Formats
In most cases, you do not need to know the file format you wish to convert since RasterMaster products automatically detect the file format regardless of the file extension. File extensions are not mandatory.
RasterMaster ActiveX supports automatic promotion of images to destination files. For example, JPEG images can only be written out at 8 and 24-bits per pixel. In order to save a 1-bit TIFF image as JPEG, the developer must promote the TIFF to 8 or 24-bits per pixel.
In our other libraries, this is accomplished by calling one of the promote functions. In RasterMaster ActiveX, however, the library automatically determines the bits per pixel for the destination format and promotes accordingly.
Supported Pixel Depths
JPEG supports 8, 24, and 32-bits per pixel, black and white images use 1-bit per pixel, while color images usually require 24-bits per pixel. For many of these cases, RasterMaster ActiveX automatically converts the pixel depth to the appropriate value, based on the output format specified.
See Format Conversion to view a sample of decompressing and saving an image to another format.
Converting Up 8 or 24-bit Pixel Depths
To convert any pixel depths up to 8 or 24-bits, use Promote8 or Promote24. See Promote24, Promote8 Property for more information.
160 Chapter 7 - File Format Conversion
Converting from 24 or 8-bit
To convert from 24 or 8-bits to 1-bit, use DiffusionMono, BayerMono or HalftoneMono. Since each uses a different algorithm, the results you get depend on the image type you are using. It is suggested to try all three.
See DiffusionMono Property, BayerMono Property, and HalftoneMono Property for more information.
File Format Conversion Error Messages
When saving to a format, if the error returned is PIXEL_DEPTH_UNSUPPORTED (-21), the output format does not support the current bits per pixel of the image you are trying to save. It is possible to convert the pixel depth of these images using the IMG_promote_8 or IMG_ promote_24 method.
See Appendix A, Supported File Formats for the pixel depths of each supported format.
161 Chapter 8 - Image Compression
Chapter 8 - Image Compression
This chapter describes how to select the best compression for an image using RasterMaster ActiveX.
Preferred Formats
Most of the compression algorithms only compress a specific type of image data. Compression techniques for 24-bit color images usually do not work well on 1-bit or bi-level images. Similarly, compression for 1-bit images do not compress well for 24-bit color images.
24-Bit Color Images
For 24-bit color images, use the JPEG format in RasterMaster ActiveX for the best conversion results.
8-Bit Gray Scale Images
For 8-bit gray scale images, use the JPEG format in RasterMaster ActiveX for the best conversion results.
1-bit Bi-Level Images
For 1-bit bi-level images, use the TIFF G4 in RasterMaster ActiveX for the best conversion results. JBIG works about twenty percent better than TIFF G4, but it can be much slower.

24-Bit Images
The best display quality depends on the type of image being viewed.
24-Bit Images Displayed on 256 Color Adapters
For 24-bit images displayed on a 256 color adapter the default behavior is to convert the image at display time to 256 colors using a simple bayer matrix dither. You can change this to a better quality diffusion dithering using the DitherMode property. However, this takes a little longer to display. See DitherMode Property for more information.
Best Quality For 24-Bit Images
By far the best quality for 24-bit images can be obtained using the OctreeColors call. Use 256 for the number of colors to optimize to. The image contains an optimized palette so you can only display one quality image at a time. See OctreeColors Property for more information.
Note: The OctreeColors call permanently changes the image to an 8-bit image. Only call the function once.
Bi-Level and 1-Bit Pixel Images
The best results for these images is obtained on text type documents.
163 Chapter 9 - Display Quality
Using the Alias Property
For bi-level or 1-bit per pixel images, set Alias to a value of 2 for scale to gray or 1 for preserve black.
When aliasing is turned on, the scaling algorithm looks at neighboring pixels to try and preserve details that might normally be lost. See Alias Property for more information.
Large Images
Large images at 200 dpi or larger must be scaled to fit on a standard resolution monitor. The default scaling skips pixels such that small lines or details may be ignored.
Scale to Gray
The scale to gray converts the neighboring pixels to an 8-bit gray scale value.
Preserve To Black
The preserve black creates a 1-bit pixel based on neighboring pixels. This has been found to work well on large engineering type drawings.
Note: It is suggested to try both the scale to gray and preserve to black to see what yields the best results on the type of images you are using.
164 Chapter 10 - Installing and Distributing an ActiveX
Chapter 10 - Installing and Distributing an ActiveX
This chapter describes how to install and distribute an ActiveX. This chapter contains the following topics:
ActiveX Overview
Installing an ActiveX for Visual Basic
ActiveX Distribution Problems
Problems Using ActiveX
Dependency Walker
ActiveX Overview
An ActiveX is a module based on Microsoft’s Object Linking and Embedding technology. One of the major features of an ActiveX is its ability to be used by a number of development environments.
When first used, an ActiveX must be registered. This can be done in the development environment or by the regsvr32.exe utility. The syntax is: regsvr32 snbd13cm.ocx.
Installing an ActiveX for Visual Basic
To install an ActiveX:
1. Select Tools. 2. Select Custom Controls. 3. Select Browse to find and select RasterMaster ActiveX.
ActiveX Distribution Problems
One of the main problems that arises when trying to distribute a program utilizing an ActiveX is the message “Load library failed or Library not found.” This happens when one or more of the following dll’s are not present in the \Windows\System directory:
l ole32.dll or later
l msvcrt20.dll or later
165 Chapter 10 - Installing and Distributing an ActiveX
l msvcrt40.dll or later
l mfcans32.dll or later
Problems Using ActiveX
When programming the ActiveX, you may get the following message: “Developers version only.” This message appears when the snbdActiveX.lic file is not present in the same directory as the ActiveX. You should not distribute this file with your application.
Dependency Walker
This tool is included in the newer version of Visual Studio. It shows the file names and version numbers that the OCX must have to run successfully.
To determine what files are missing, compare an install that works correctly with one that does not.
166 Chapter 11 - OCX/VBX Properties
Chapter 11 - OCX/VBX Properties
This chapter describes the RasterNote Annotation and Redlining toolkit and library. Snowbound RasterNote is an optional tool for RasterMaster ActiveX. Contact sales for more information.
The library is called from the developer’s application. Annotation objects are created through an interface and then stored in one or more annotation layers; each stored as a separate file. The annotation objects are registered with the underlying image permitting zooming and scrolling of the overall display without losing registration of the annotation information. The display of the underlying image can be managed through the use of Snowbound’s RasterMaster ActiveX product or any other application or tool that displays images.

176 Chapter 12 - Working with PDF and Other Document File Formats
Chapter 12 - Working with PDF and Other Document File Formats
This chapter describes how to work with PDF and other document file formats in Snowbound Software’s RasterMaster ActiveX product. The chapter contains the following topics:
Working with Document File Formats
Reading and Writing Support for PDF File Formats
Working with Document File Formats
Snowbound Software supports many document file formats in most of its viewing, converting, and RasterMaster SDK products.
The supported file formats include:
l PDF - Adobe portable file
l PCL - Hewlett Packard printer format
l DOC - Microsoft Word processor format
l XLS - Microsoft Excel spreadsheet format
l PPT - Microsoft PowerPoint presentation format
l RTF - Rich text file format
l AFP and MODCA - IBM advanced printing format
These like any other file formats supported by Snowbound Software’s products are read in using a call such as IMG_decompress_bitmap(). For ActiveX, use the Image property. Snowbound Software’s products auto-detect the file format so there is no need to specify which format you are reading. You do not even need a specific extension.
These formats contain graphics commands such as line and text drawing. This differs from bitmap formats that are a 2-dimensional array of bytes forming a picture. Normally, documents are drawn or “rendered” to a bitmap in RasterMaster, but RasterMaster can also produce searchable text documents.
The following property returns or sets the default dots per inch (DPI) for imported PDF files: PdfDpi
Saving
This property sets the destination size for saving PDF files. The xsize and ysize are the output sizes in points. A point is 1/72 of an inch. Only PDF, PCL, and AFP file formats can be saved.
177 Chapter 12 - Working with PDF and Other Document File Formats
The PCL and APF file formats are saved as bitmap. The PDF file format can be saved as bitmap or searchable text.
You can specify the output size with PDF using the following properties: PdfXPageSize
Table 12.1: PdfXPageSize Property Setting
Setting Description PdfXPageSize Sets the output PDF page xsize in points.
PdfYPageSize
Table 12.2: PdfYPageSize Property Settings
Setting Description PdfYPageSize Sets the output PDF page ysize in points.
Reading and Writing Support for PDF File Formats
Reading and writing support for PDF formats is included in the following RasterMaster Imaging SDK products:
l RasterMaster Imaging SDK for Windows DLL
l RasterMaster Imaging SDK for ActiveX
l RasterMaster Imaging SDK for .NET
l RasterMaster Imaging SDK for the Java™ Platform
Currently, Snowbound Software does not provide PDF reading support in UNIX and Macintosh products. Snowbound Software does provide PDF writing support for its UNIX and Macintosh products.
PDF reading is available as a separate option. For the RasterMaster Imaging SDK for Java, a special PDF version is available. For the other RasterMaster products, the pdfplug.dll file is required for PDF reading support. This file must be included in the same directory as the ActiveX, .NET library, or RasterMaster DLL. You can also include the file in the following directory: \Windows\system.
Reading or Decompressing a PDF Document
To read in or decompress a PDF document, use any of the decompression calls such as IMG_ decompress_bitmap(). For RasterMaster ActiveXX, use the Image property. All RasterMaster Imaging SDK products automatically detect the file format and do not use the extension on the file name.
The default size for decompressing PDF documents is 200 dots per inch (DPI) and 24 bits per pixel. To alter this or to convert PDF files, you can call the IMGLOW_set_pdf_input
178 Chapter 12 - Working with PDF and Other Document File Formats
(dpi,dots_per_inch) function. For RasterMaster ActiveX, call the PdfDpi and PdfBitsPerPixel properties.
Saving to a PDF Document
All RasterMaster Imaging SDK products support writing PDF files. To save a file as PDF, use any of the saving calls such as IMG_save_bitmap() with the file format set to PDF or the file type constant number 59.
Working with Black and White Images
If you are working with black and white documents, you will save a lot of memory and increase performance by setting the DPI to 300 or 200 and the bits per pixel to 1 when reading PDF images. For 1-bit or black and white images, RasterMaster will write out or save a PDF with CCITT - G4 compression for black and white images.
Working with Color Images
For color bitmaps, a PDF will be created with JPEG compression.
Changing Output Page Size
The default page size is set to 8.5 x 11. The bitmap image saved is centered at this page. To alter the output page size, use the call IMGLOW_set_pdf_output. For RasterMaster ActiveX, use the PdfXPageSize and PdfYPageSize properties. The xsize and ysize parameters are the page size in points or 1/72 of an inch.
Performance
If you are working with black and white documents, you will save a lot of memory and increase performance by setting the DPI to 300 or 200 and the bits per pixel to 1 when reading all document formats.
179 Appendix A - Supported File Formats
Appendix A - Supported File Formats
This appendix describes the file type number and read/write capabilities of all supported file formats.
RasterMaster ActiveX is a powerful conversion tool that can transform your documents and images into many different formats. Some format types are limited in the amount of color (bit- depth) they support in an image. Some file formats read and write only black and white (1-bit deep) and other file formats support only color images (8+ bits deep). For many of these cases, RasterMaster ActiveX automatically converts the pixel depth to the appropriate value, based on the output format specified. The chart below will help you determine whether your black and white or color document will be able to convert straight to the desired output format with no additional processing.

File Format Description 1-bit Black and white or monochrome images Grayscale images, that may appear to be black and white, but 4-bit, 8-bit, 16-bit contain much more information, and are much larger than 1-bit 8-bit, 16-bit,24-bit, 32-bit Full color images
When saving to a format, if the error returned is PIXEL_DEPTH_UNSUPPORTED (-21), the output format does not support the current bits per pixel of the image you are trying to save. The chart below will help you identify formats with compatible bit depths.
Please note that the higher the bit depth (bits per pixel), then the larger the size of the image on the disk or in memory. The higher bit depth may offer more quality, but the performance may suffer because there is a lot more image data to process. Many users may have images that appear to be black and white, however, they are stored in 24-bit color. Converting these documents to a 1-bit file format will decrease the size of the file and improve performance with no perceivable loss in quality.
If you have any questions about what format to select you may contact Snowbound Technical support on the web at http://support.snowbound.com .

This appendix describes how to install the evaluation or full copy of the Snowbound RasterMaster ActiveX Imaging SDK software. The appendix contains the following topics:
Overview of the Installation Process
Minimum Requirements
Installing the Software
Directory Structure
Installed Files
Overview of the Installation Process
RasterMaster ActiveX is easy to install as an evaluation, developer, or run-time version. The evaluation copy is delivered as a .zip archive that can be manually extracted to an installation directory chosen by the user.
You can get an evaluation by contacting a member of our sales team at [email protected] or 1-617-607-2010. The evaluation copy expires at the end of each month.
Both the developer and runtime version of RasterMaster ActiveX ship as fully serialized builds which are very easy to install. This product is fully enabled as either a developer or runtime product.
RasterMaster ActiveX is delivered as a .zip archive that can be manually extracted to an installation directory chosen by the user. For example: C:\Program Files\Snowbound\RMActiveX
Notes: For RasterMaster ActiveX, Snowbound requests that you place all Snowbound components in a non-common directory within Windows. They should NOT be placed in the \windows or \windows\system directory or other such common area.
Starting with version 14, RasterMaster ActiveX’s file naming convention will no longer include the version number in the file name and will follow a generic naming convention. For example, in the previous version, the file named snbd13cm.dll will now be named snbdcm.dll.
199 Appendix B - Software Installation
When a developer's license is purchased, a Developer’s Version banner appears. You must interactively select the notification box for the program to continue. Contact sales if you need to eliminate this notification for your development purposes.
When a distribution license is purchased, all banners disappear.
Note: You are running an evaluation version of the software if an evaluation banner appears on the screen. Contact support at http://support.snowbound.com for help with these issues. If you download an update or received one from Snowbound technical support, please ensure that you obtain a serialized version of the product before you go into distribution.
Minimum Requirements
To install RasterMaster ActiveX, you must meet certain minimum processor speed and RAM requirements.
Minimum Processor Speed RasterMaster ActiveX must be installed on a 100Mhz Pentium processor or greater. When installing the PDF processing version, or when dealing with large images, you should have the fastest possible processor.
Minimum RAM The computer where you are installing RasterMaster ActiveX must have at least 128 MB of RAM. The more RAM, the better.
What to Expect When Installing an Evaluation Version
Your evaluation is a full version of the product with the following limitations:
l You will see a pop up banner when you view or convert your first document. Subsequent documents in the same session will not elicit the banner.
l You will see large thin Xs across each page after the first 50 pages or thumbnails.
l After your expiration date, you will see a banner stating the evaluation has expired. You will not see any output.
Other than that you will have full use of the product including support for all document formats.
What to Expect in a Production Version
When you purchase RasterMaster ActiveX, you will receive a set of fully licensed binary files. The files will include snbd*.dll and .lib and .dlls for each purchased option. Please see Installed Files for a list of the files installed with RasterMaster ActiveX.
200 Appendix B - Software Installation
Installing the Production Version of RasterMaster ActiveX
Install and configure the evaluation version of the product on your target production system. Ensure it is working as you intended. Extract the binary files from the production version package and use those to replace the same files in the evaluation version that you have installed. Once the production files are in place you will no longer see banners or Xs. You will only see expiration messages if you try to view a document of a type that you did not purchase, for example MS Office or AFP/MO:DCA.
Installing the Software
There are three different versions of RasterMaster ActiveX that can be installed; traditional SDK, SDK with PDF, and SDK with ABIC.

226 Appendix C - Samples Using Visual Basic V4.0
Since there is no way to know how large an image will be once saved to memory, get the original compressed file size and add about 20KB (assuming you have done nothing to the image). If you're saving to a different file format, e.g., from TIFF_G4_FAX to JPEG or GIF, you need to take the uncompressed file size, and multiply by 8 or 24 (depending on the pixel depth you are saving to). You must do this because TIFF_G4_FAX has only 1-bit per pixel, whereas JPEG and GIF can be 8, 24, or 32-bits per pixel. This automatically makes the uncompressed file size 8, 24, or 32 times larger.
This affects the final compression ratio, but it is impossible to know the final size of the compressed image. For JPEG and GIF you should probably assume 2 or 3 to 1 for the compression ratio. What does that mean? Take the uncompressed size of the image and divide by 2 or 3 and that is how much memory you should allocate (the size of the byte array) for saving.
Note: There is an issue saving to a byte array in Visual Basic. VB5 does not understand a pointer to a byte array, it does, however, understand a pointer to the first element (for you C/C++ programmers, yes, we know it's the same thing), so we use the function VarPtr (which cannot handle a pointer to an array, but it can handle a pointer to an element in the array), and pass the resulting pointer to ocxSnowbound.MemSave.
Listed below are the properties used in this sample.
FlipX Property when set to true, flips the image in the control horizontally or swaps pixels along the X axis around the center of the image.
FlipY Property when set to true, flips the image in the control vertically or swaps pixels along the Y axis around the center of the image.

Setting Up .NET
You can use RasterMaster ActiveX components from within Microsoft Visual Basic .NET. The current version of the Snowbound RasterMaster ActiveX is fully compatible with Visual Basic .NET.
Note: While these procedures are specifically for setting up RasterMaster ActiveX with Visual Basic .NET, the procedures for Visual C++ .NET and Visual C# .NET are similar.
Creating a New Project
The first step in setting up Visual Basic .NET is to create a new project.
To create a new project:
1. From the main Visual Studio .NET dialog, choose File > New > Project. The New Project dialog opens.
244 Appendix F - Using RasterMaster ActiveX with Visual Basic .NET
2. Choose Project Types > Visual Basic Projects. 3. Choose Templates > Windows Application. 4. Click OK. The project opens with a default, empty form.
Adding the Snowbound Control to the Toolbox
The next step in setting up Visual Basic .NET to work with RasterMaster ActiveX is to add the Snowbound control to the toolbox.
To add the Snowbound control to the toolbox:
1. Choose Project > Add Reference. The Add Reference dialog opens.
245 Appendix F - Using RasterMaster ActiveX with Visual Basic .NET
2. Click Browse and navigate to the directory containing the snbdXym.ocx.
Replace X with your version number, and Y with your product level-usually ‘d’ or ‘c’.
3. Click Open. 4. Click OK to close the Add Reference dialog.
Adding the Control to the Form
After the control has been added to the toolbox, the control must be added to the form.
To add the control to the form:

3. Right-click Customize Toolbox from the context menu to display the Customize Toolbox dialog. 4. Select the COM Components tab.
252 Appendix G - Using RasterMaster ActiveX with Visual C# .NET
5. Select the Snowbound Control.
If it the Snowbound control is not present, navigate to the directory containing the RasterMaster ActiveX control. By default, the control is in the C:\Program Files\Snowbound\RM
6. Once you have located the ActiveX control, double-click it and click OK. 7. Mark the checkbox next to the Snowbound control and click OK.
Adding the Control to the Form
After the control has been added to the toolbox, the control must be added to the form.
To add the control to the form:
1. From the IDE dialog, drag the control from the Components tab and drop it onto the form.
253 Appendix G - Using RasterMaster ActiveX with Visual C# .NET
2. Move your cursor over the blank form. The mouse icon will look like . 3. Add a button to the form.
Follow the standard procedure for adding Microsoft controls to a form.
4. Double-click the new button on the form to display the code view.
254 Appendix G - Using RasterMaster ActiveX with Visual C# .NET
The code view dialog places your cursor on an empty line between brackets.
Example G.1:Placing Cursor on an Empty Line
private void button1_Click(object sender, System.EventArgs e) { }
5. Add the line of code shown below between the brackets (the information in bold). This code is needed for loading the image once the button is clicked.
Example G.2: Loading the Image When Button Clicked
private void button1_Click(object sender, System.EventArgs e) { this.axSnbdocx1.Image = "c:\\images\\myimage.tif"; }
Note: By default, the Snowbound ActiveX control is named axSnbdocx1. To change the
255 Appendix G - Using RasterMaster ActiveX with Visual C# .NET name, follow the standard procedure for renaming controls in the Visual Studio .NET manual.
6. Click Debug .
The project runs and the IDE creates a new window with the RasterMaster ActiveX control and a single button.
7. Click the newly created button to display the image.
Building Your Application for Distribution
This section describes how to prepare your application for distribution.
To create a distributable version of your application:
1. From the IDE dialog, choose Build > Build Solution.
2. In Windows Explorer, navigate to the directory containing your application. By default the directory is C:\Documents and Settings\
256 Appendix G - Using RasterMaster ActiveX with Visual C# .NET
Note: The AxInterop.SnbdocxLib.dll, Interop.SnbdocxLib.dll, and ProjectName.exe should also be in this directory.
3. Copy all of the files into a common build directory. 4. Navigate to the directory containing the RasterMaster ActiveX control. By default the control is in the C:\Program Files\Snowbound\RM
The following files should also be in this directory:
Example G.3: Directory for the Control
AxSnbdocxLib.dll, SnbdocxLib.dll, and snbd
5. Copy all of the files to the common build directory that you created earlier.
Note: If you upgrade the RasterMaster ActiveX control, you need to replace all peripheral DLLs in addition to the OCX file, then rebuild your application with the new components prior to distribution.
257 Appendix H - TIFF Tags
Appendix H - TIFF Tags
This appendix describes the tags in the header and in Image File Directories (IFDs) used by TIFF (tagged image file format) files to declare and describe their content. Each TIFF file begins with a image file header which points to one or more image file directories which contain the image data and image information.
The TIFF file format was created by an independent group and was supported by Aldus. .TIF files can be any number of bits per pixel, planes and several compression algorithms. The byte order may be Intel or Motorola format. The bytes may also be filled from right to left or left to right. Compression may be uncompressed, pack bits, LZW, modified Huffman, CCITT G4, CCITT G3, CCITT G3-2D or JPEG. The CCITT G4 file format only saves to black and white.
If you have any questions about the TIFF file format and the tags described below, you may contact Snowbound Technical support on the web at http://support.snowbound.com .
Sources for Tag Specifications
The following are descriptions of the types of the sources of the tags:
TIFF Baseline: The baseline set of tags were documented in TIFF 5.0 and carried over on pages 11-47 of the 1992 TIFF 6.0 specification.
TIFF Extended: The extended set includes some additional tags and added values for existing tags, as documented on pages 48-115 of the TIFF 6.0 specification.
TIFF Private: Originally, the term private meant just that. The TIFF 6.0 specification (page 8) states, “An organization might wish to store information meaningful to only that organization . . . . Tags numbered 32768 or higher, sometimes called private tags, are reserved for that purpose. Upon request, the TIFF administrator . . . will allocate and register one or more private tags for an organization . . . . You do not need to tell the TIFF administrator what you plan to use them for, but giving us this information may help other developers to avoid some duplication of effort.” Over time, however, many private tags have become well established and well documented, e.g., tag 34675 for the ICC profile, dubbed InterColorProfile in the TIFF/EP standard. Thus, many members of the private tag class can be viewed as open extensions rather than as containers for secret information.
TIFF/EP, TIFF/IT, and DNG: A number of tags, some of which may once have been private, have been defined in TIFF/EP (ISO 12234-2, 2001), TIFF/IT (ISO 12639, 2004), and DNG_1_1, an Adobe-sponsored extension of the TIFF 6.0 specification.
TIFF Private IFD: The TIFF 6.0 specification (page 9) states, “If you need more than 10 tags, we suggest that you reserve a single private tag, define it as a LONG TIFF data type, and use its value as a pointer (offset) to a private IFD [image file directory] or other data structure of your choosing. Within that IFD, you can use whatever tags you want, since no one else will know that it is an IFD unless you tell them.” As with private tags, we can understand private IFDs as an extension to TIFF, often very public and well documented.
258 Appendix H - TIFF Tags
The private IFD tags of greatest interest to the Library of Congress are those associated with the EXIF_2_2 specification, pertaining to image generation by digital still cameras. Exif is an abbreviation for EXchangeable Image File format, although Exif does not relate to TIFF as, say, JFIF relates to JPEG_DCT. The Exif IFD is pointed to by the Private Exif IFD tag 34665. This and other Exif tags are listed in the numerical table below.
For the Exif specification and other related information, see Exif.org. There are actually three private IFDs specified by the Exif standard. The other two are the GPS IFD, for positioning information, and the Interoperability IFD, used to encode compability information. With numerical sequences of their own, the GPS and interoperability tags are not included in the table below.
HD Photo tags: Although not a true TIFF implementation, WMP_1_0 (originally called Windows Media Photo) is a 2006 specification with a container format that borrows heavily from TIFF and adds a few new tags of interest. Included in the table.
Descriptions of Tags in Numerical Order
Table H.1: TIFF Tags in Numerical Order1
Code Source of Name Description Dec Hex Tag A general indication of the kind of data that is contained in this subfile. This field is made up of a set of 32 flag bits. Unused bits are expected to be 0. Bit 0 is the low-order bit.
Currently defined values for the bitmap are:
254 00FE NewSubfileType 0 - Image is reduced of another TIFF image in Baseline this file
1 - Image is a single page of a multi-page
2 - Image is a transparency mask for another image in this file.
The default is 0. A general indication of the kind of data that is contained in this subfile.
Currently defined values are:
A general indication of the kind of data that is 255 00FF SubfileType contained in this subfile. Baseline
Currently defined values are:
1 = full resolution image data - ImageWidth, ImageLength, and StripOffsets are required fields.
259 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag 2 = reduced resolution image data - ImageWidth, ImageLength, and StripOffsets are required fields. It is further assumed that a reduced resolution image is a reduced version of the entire extent of the corresponding full resolution data.
3 = single page of a multi-page image (see the PageNumber tag description).
Continued use of this field is not recommended. Writers should instead use the new and more general NewSubfileType field. The image's width, in pixels (X:horizontal). The 256 0100 ImageWidth Baseline number of columns in the image. The image's length (height) in pixels (Y:vertical). 257 0101 ImageLength The number of rows (sometimes described as Baseline "scan lines") in the image. Number of bits per sample. Note that this tag allows a different number of bits per sample for each sample corresponding to a pixel. For 258 0102 BitsPerSample example, RGB color data could use a different Baseline number of bits per sample for each of the three color planes.
The default is 1. 1 = No compression, but pack data into bytes as tightly as possible, with no unused bits except at the end of a row. The bytes are stored as an array of bytes, for BitsPerSample <= 8, word if BitsPerSample > 8 and <= 16, and dword if BitsPerSample > 16 and <= 32. The byte ordering of data >8 bits must be consistent with that specified in the TIFF file header (bytes 0 and 1). Rows are required to begin on byte boundaries. 259 0103 Compression Baseline 2 = CCITT Group 3 1-Dimensional Modified Huffman run length encoding. See ALGRTHMS.txt BitsPerSample must be 1, since this type of compression is defined only for bilevel images (like FAX images...)
3 = Facsimile-compatible CCITT Group 3, exactly as specified in "Standardization of Group 3 facsimile apparatus for document
260 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag transmission," Recommendation T.4, Volume VII, Fascicle VII.3, Terminal Equipment and Protocols for Telematic Services, The International Telegraph and Telephone Consultative Committee (CCITT), Geneva, 1985, pages 16 through 31. Each strip must begin on a byte boundary. (But recall that an image can be a single strip.) Rows that are not the first row of a strip are not required to begin on a byte boundary. The data is stored as bytes, not words - byte-reversal is not allowed. See the Group3Options field for Group 3 options such as 1D vs 2D coding.
4 = Facsimile-compatible CCITT Group 4, exactly as specified in "Facsimile Coding Schemes and Coding Control Functions for Group 4 Facsimile Apparatus," Recommendation T.6, Volume VII, Fascicle VII.3, Terminal Equipment and Protocols for Telematic Services, The International Telegraph and Telephone Consultative Committee (CCITT), Geneva, 1985, pages 40 through 48. Each strip must begin on a byte boundary. Rows that are not the first row of a strip are not required to begin on a byte boundary. The data is stored as bytes, not words. See the Group4Options field for Group 4 options.
5 = LZW Compression, for grayscale, mapped color, and full color images. See ALGRTHMS.txt
32773 = PackBits compression, a simple byte oriented run length scheme for 1-bit images.
Data compression only applies to raster image data, as pointed to by StripOffsets.
The default value is 1. 0 = For bilevel and grayscale images: 0 is imaged as white. 2**BitsPerSample-1 is imaged as black. If GrayResponseCurve exists, it PhotometricInterpre- 262 0106 overrides the PhotometricInterpretation value. Baseline tation 1 = For bilevel and grayscale images: 0 is imaged as black. 2**BitsPerSample-1 is imaged as white. If GrayResponseCurveexists, it
261 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag overrides the PhotometricInterpretation value.
2 = RGB. In the RGB model, a color is described as a combination of the three primary colors of light (red, green, and blue) inparticular concentrations. For each of the three samples, 0 represents minimum intensity, and 2**BitsPerSample - 1 represents maximum intensity. For PlanarConfiguration = 1, the samples are stored in the indicated order: first Red, hen Green, then Blue. For PlanarConfiguration = 2, the StripOffsets for the sample planes are stored in the indicated order: first the Red sample plane StripOffsets, then the Green plane StripOffsets, then the Blue plane StripOffsets.
3 = "Palette color." In this mode, a color is described with a single sample. The sample is used as an index into ColorMap. The sample is used to index into each of the red, green and blue curve tables to retrieve an RGB triplet defining an actual color. When this PhotometricInterpretation value is used, the color response curves must also be supplied. SamplesPerPixel must be 1.
4 = Transparency Mask. This means that the image is used to define an irregularly shaped region of another image in the same TIFF file. SamplesPerPixel and BitsPerSample must be 1. PackBits compression is recommended. The 1- bits define the interior of the region; the 0-bits define interior of the region; the 0-bits define the exterior of the region. The Transparency Mask must have the same ImageLength and ImageWidth as the main image. 1 = a bilevel "line art" scan. BitsPerSample must be 1.
2 = a "dithered" scan, usually of continuous tone 263 0107 Threshholding Baseline data such as photographs. BitsPerSample must be 1.
3 = Error Diffused. The width of the dithering or halftoning matrix 264 0108 CellWidth Baseline used to create a dithered or halftoned bilevel file.
262 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag The length of the dithering or halftoning matrix 265 0109 CellLength Baseline used to create a dithered or halftoned bilevel file. 266 010A FillOrder The logical order of bits within a byte. Baseline The name of the document from which this 269 010D DocumentName Extended image was scanned. A string that describes the subject of the image. For example, a user may wish to attach a 270 010E ImageDescription Baseline comment such as "1988 company picnic" to an image. Manufacturer of the scanner, video digitizer. 271 010F Make Baseline Mandatory for TIFF/EP. The model name/number of the scanner, video digitizer. This tag is intended for user information 272 0110 Model only so format is arbitrary. Baseline
Mandatory for TIFF/EP. For each strip, the byte offset of that strip. The offset is specified with respect to the beginning of the TIFF file. Note that this implies that each strip has a location independent of the locations 273 0111 StripOffsets Baseline of other strips. This feature may be useful for editing applications. This field is the only way for a reader to find the image data, and hence must exist. The orientation of the image with respect to the rows and columns.
1 = The 0th row represents the visual top of the image, and the 0th column represents the visual left hand side.
2 = The 0th row represents the visual top of the image, and the 0th column represents the visual right hand side.
274 0112 Orientation 3 = The 0th row represents the visual bottom of Baseline the image, and the 0th column represents the visual right hand side.
4 = The 0th row represents the visual bottom of the image, and the 0th column represents the visual left hand side.
5 = The 0th row represents the visual left hand side of the image, and the 0th column represents the visual top.
263 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag 6 = The 0th row represents the visual right hand side of the image, and the 0th column represents the visual top.
7 = The 0th row represents the visual right hand side of the image, and the 0th column represents the visual bottom.
8 = The 0th row represents the visual left hand side of the image, and the 0th column represents the visual bottom.
It is extremely costly for most readers to perform image rotation "on the fly", i.e., when importing and printing; and users of most desktop publishing applications do not expect a file imported by the application to be altered permanently in any way.
The default value is 1. The number of samples per pixel. SamplesPerPixel is 1 for bilevel, grayscale, and 277 0115 SamplesPerPixel Baseline palette color images. SamplesPerPixel is 3 for RGB images. The number of rows per strip. The image data is organized into strips for fast access to individual rows when the data is compressed - though this 278 0116 RowsPerStrip field is valid even if the data is not compressed. Baseline The default is 2**32 - 1, which is effectively infinity. That is, the entire image is one strip. Recomended is a strip size of 8K. For each strip, the number of bytes in that strip. The existenceof this field greatly simplifies the 279 0117 StripByteCounts Baseline chore of buffering compressed data, if the strip size is reasonable. 280 0118 MinSampleValue The minimum component value used. Baseline 281 0119 MaxSampleValue The maximum component value used. Baseline The number of pixels per ResolutionUnit in the X 282 011A XResolution Baseline direction, i.e., in the ImageWidth direction. The number of pixels per ResolutionUnit in the Y 283 011B YResolution Baseline direction, i.e., in the ImageLength direction. 1 = The sample values for each pixel are stored contiguously, so that there is a single image 284 011C PlanarConfiguration plane. See PhotometricInterpretation to Baseline determine the order of the samples within the pixel data. So, for RGB data, the data is stored
264 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag RGBRGBRGB...and so on.
2 = The samples are stored in separate "sample planes." The values in StripOffsets and StripByteCounts are then arranged as a 2- dimensional array, with SamplesPerPixel rows and StripsPerImage columns. (All of the columns for row 0 are stored first, followed by the columns of row 1, and so on.) PhotometricInterpretation describes the type of data that is stored in each sample plane. For example, RGB data is stored with the Red samples in one sample plane, the Green in another,and the Blue in another.
If SamplesPerPixel is 1, PlanarConfiguration is irrelevant, and should not be included.
The default is 1. The name of the page from which this image was 285 011D PageName Extended scanned. The X offset of the left side of the image, with 286 011E XPosition respect to the left side of the page, in Extended ResolutionUnits. The Y offset of the top of the image, with respect to the top of the page, in ResolutionUnits. In the 287 011F YPosition Extended TIFF oordinate scheme, the positive Y direction is down, so that YPosition is always positive. For each string of contiguous unused bytes in a 288 0120 FreeOffsets Baseline TIFF file, the byte offset of the string. For each string of contiguous unused bytes in a 289 0121 FreeByteCounts Baseline TIFF file, the number of bytes in the string. The precision of the information contained in the GrayResponseCurve.
1 = Number represents tenths of a unit.
2 = Number represents hundredths of a unit.
3 = Number represents thousandths of a unit. 290 0122 GrayResponseUnit Baseline 4 = Number represents ten-thousandths of a unit.
5 = Number represents hundred-thousandths of a unit.
For historical reasons, the default is 2. However, for greater accuracy, 3 is recommended. GrayResponseCurv-For grayscale data, the optical density of each 291 0123 Baseline e possible pixel value.
265 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag The purpose of the gray response curve and the gray units is to provide more exact photometric interpretation information for gray scale image data, in terms of optical density. Those options are for fax-images stored in TIFF format. This field is made up of a set of 32 flag bits. Unused bits are expected to be 0. It is probably not safe to try to read the file if any bit of this field is set that you don't know the meaning of. 292 0124 Group3Options Extended Bit map:
0 - 2-dimensional coding used.
1 - Image is uncompressed
2 - Fill bits have been added before EOL codes, so that EOL always ends on a byte boundary. This field is made up of a set of 32 flag bits and is used for the images with fax group 4 compression. Unused bits are expected to be 0. It is probably not safe to try to read the file if any bit of this field is set that you don't know the meaning of. Gray scale and color coding schemes are under study, and will be added when finalized.
For 2-D coding, each strip is encoded as if it were a separate image. In particular, each strip Group4Options 293 0125 begins on a byte boundary; and the coding for the Extended first row of a strip is encoded independently of the previous row, using horizontal codes, as if the previous row is entirely white. Each strip ends with the 24-bit end-of-facsimile block (EOFB).
Bit map:
0 - reserved (unused)
1 - uncompressed mode is used
2-31 - reserved To be used with XResolution and YResolution.
1 = No absolute unit of measurement. Used for 296 0128 ResolutionUnit Baseline images that may have a non-square aspect ratio, but no meaningful absolute dimensions. The
266 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag drawback of ResolutionUnit=1 is that different applications will import the image at different sizes. Even if the decision is quite arbitrary, it might be better to use dots per inch or dots per centimeter, and pick XResolution and YResolution such that the aspect ratio is correct and the maximum dimension of the image is about four inches (the "four" is quite arbitrary.)
2 = Inch.
3 = Centimeter.
The default is 2. This tag is used to specify page numbers of a multiple page (e.g. facsimile) document. Two word values are specified. The first value is the 297 0129 PageNumber page number; the second value is the total Extended number of pages in the document. Note that pages need not appear in numerical order. The first page is 0 (zero). Describes a transfer function for the image in 301 012D TransferFunction Extended tabular style. Name and release number of the software 305 0131 Software package that created the image. User Baseline information only. Date and time of image creation.

267 Appendix H - TIFF Tags
Code Source of Name Description Dec Hex Tag 1 = Continuous tone, natural image.
2 = Synthetic image, using a greatly restricted range of colors.
Such images are produced by most color paint programs. See ColorList for a list of colors used in this image.
The default value is 1. A list of colors that are used in this image. Use of this field is only practical for images containing a greatly restricted (usually less than or equal to 256) range of colors. ColorImageType should be 2. See ColorImageType.
319 013F ColorList The list is organized as an array of RGB triplets, Extended with no pad. The RGB triplets are not guaranteed to be in any particular order. Note that the red, green, and blue components can either be a BYTE or a word in length. BYTE should be sufficient for most applications. This tag defines a Red-Green-Blue color map for palette color images. The palette color pixel value is used to index into all 3 subcurves. The subcurves are stored sequentially. The Red entries come first, followed by the Green entries, 320 0140 ColorMap followed by the Blue entries. The width of each Baseline entry is 16 bits, as implied by the type of word. 0 represents the minimum intensity, and 65535 represents the maximum intensity.
ColorMap must be included in all palette color images.

290 Appendix J - Troubleshooting
Appendix J - Troubleshooting
This appendix describes solutions to issues that you may run across when installing and using RasterMaster ActiveX.
Receiving an Error Code When Loading, Saving or Converting a Document
If you receive an error code when trying to load, save or convert a document with RasterMaster ActiveX, please check the list of error codes and their descriptions in Appendix I, Snowbound Error Codes to determine the source of the issue. If you still cannot resolve the issue after looking at the list of error codes, please submit a support ticket at http://support.snowbound.com and include the error code and the document that you were trying to load, save or convert when you got the error message.
Output Document Differs from Original Document
When you convert a document and the output document is different from the original document, please create a support ticket at http://support.snowbound.com and attach the document along with a screenshot of the output document in RasterMaster ActiveX. Some examples of the differences that may occur include missing data, missing text, distorted graphics or displaying an incorrect or different font. We can test the document with the latest release of RasterMaster ActiveX which contains fixes which may resolve your issue.
Output Document Displays Incorrect or Missing Characters
When you convert a document, the output document may display incorrect or missing characters if the document contains special characters which are commonly found in Non- English languages such as Chinese, Japanese and Thai. Make sure that your system is properly configured to support these characters. For more information, please see Snowbound Software’s Font Configuration Guide.
Identifying an Unknown File Format
To identify an unknown file format, you can use the FileType Property function in RasterMaster ActiveX. This function returns a number that corresponds to a file type as defined in the RasterMaster library. Please see Appendix A,Supported File Formats for a list of the Snowbound file type constants.
291 Appendix J - Troubleshooting
Scanning Error
If the ERROR_OPENING_SCANNER (-16) is being returned, then check that the control is visible. You can set the height and width of the control to be very small (1) to make it nearly invisible or hide it behind something. However the control Visible Property has to be true so it can process the Windows messages and communicate with the scanner.
Color Annotations Appear Black and White or Not at All
If color annotations appear black and white or do not appear at all after an image is converted, make sure that the bit depth for the AnnMerge property is set to 24 before the image is decompressed for color annotations to appear. For more information, please see the AnnMerge Property .
Receiving a -3 Corrupted File Error code
If you receive a -3 corrupted file error code, the input document may have become corrupt. To resolve this issue, open the document in an editor and write it back out again.
Some PDF document generators do not properly specify all of the information needed in a document. To resolve this issue in PDF documents that are generated by custom applications, open the document in Adobe Acrobat and then save it. You should then be able to process the newly saved document in RasterMaster ActiveX.
Overlay Resources Not Pulled into APF or MODCA Document
If overlay resources such as signatures are not being pulled into an AFP or MODCA document, then make sure that the resource filename does not have a filename extension. If the resource filename has a filename extension, remove it.
Searching for Text in a Snowbound Software Generated PDF
If you are having trouble finding text in a Snowbound Software generated searchable PDF, please use Adobe Reader version 9.4 to do the search.
Some TIFF_JPEG Files Produced By RasterMaster ActiveX Do Not Open In Third Party Image Viewers
When converting a file to TIFF_JPEG with RasterMaster ActiveX, you may see that the resulting TIFF is blank when opened in a third party image viewer such as MS Office Document
292 Appendix J - Troubleshooting
Imaging or Windows Photo Viewer. In some cases, the viewer may also display an error message indicating that the TIFF is corrupted or too large.
This issue typically occurs when the file in question is converted at 1-bit black and white or 8-bit grayscale, rather than 24-bit color. By default, RasterMaster ActiveX will often choose 1 bit/pixel to ensure better performance during conversion. Formats which are converted to 1-bit by default include AFP, DOC, XLS, and PCL. For these formats, we recommend that you call the IMGLOW_set_document_input() method prior to decompression if you wish to convert to TIFF_JPEG. Please see the following example: status = s.IMGLOW_set_document_input(200, 24, Defines.DOC) status = s.IMG_decompress_bitmap("C:\\input\\file.doc", page); status = s.IMG_save_bitmap("C:\\output\\file.tif", Defines.TIFF_JPEG)
In the above example, the input DPI and bit-depth are set to 200 and 24 respectively for the input DOC file before being converted to TIFF_JPEG.
Please also note that while color input images (e.g. JPEG, TIFF, PNG) will be converted to 24 bits/pixel by default, you still might see this issue for black and white or grayscale input images. In the case where your input file is a black and white or grayscale image, you can promote the bit-depth to 24 by calling IMG_promote_24() after decompression. Please see the following example: status = s.IMG_decompress_bitmap("C:\\input\\file.png", page); status = s.IMG_promote_24(); status = s.IMG_save_bitmap("C:\\output\\file.tif", Defines.TIFF_JPEG)
This should produce an output TIFF that can be viewed by most third party image viewers.
