Exploring the .BMP File Format
Exploring the .BMP File Format Don Lancaster Synergetics, Box 809, Thatcher, AZ 85552 copyright c2003 as GuruGram #14 http://www.tinaja.com [email protected] (928) 428-4073 The .BMP image standard is used by Windows and elsewhere to represent graphics images in any of several different display and compression options. The .BMP advantages are that each pixel is usually independently available for any alteration or modification. And that repeated use does not normally degrade the image. Because lossy compression is not used. Its main disadvantage is that file sizes are usually horrendous compared to JPEG, fractal, GIF, or other lossy compression schemes. A comparison of popular image standards can be found here. I’ve long been using the .BMP format for my eBay and my other phototography, scanning, and post processing. I firmly believe that… All photography, scanning, and all image post-processing should always be done using .BMP or a similar non-lossy format. Only after all post-processing is complete should JPEG or another compressed distribution format be chosen. Some current examples of my .BMP work now do include the IMAGIMAG.PDF post-processing tutorial, the Bitmap Typewriterthat generates fully anti-aliased small fonts, the Aerial Photo Combiner, and similar utilities and tutorials found on our Fonts & Images, PostScript, and on our Acrobat library pages. A few projects of current interest involving .BMP files include true view camera swings and tilts for a digital camera, distortion correction, dodging & burning, preventing white punchthrough on knockouts, and emphasis vignetting. Mainly applied to uncompressed RGBX 24-bit color .BMP files. -
The LAS File Format Contains a Header Block, Variable Length
LAS Specification Version 1.2 Approved by ASPRS Board 09/02/2008 LAS 1.2 1 LAS FORMAT VERSION 1.2: This document reflects the second revision of the LAS format specification since its initial version 1.0 release. Version 1.2 retains the same structure as version 1.1 including identical field alignment. LAS 1.1 file Input/Output (I/O) libraries will require slight modifications in order to be compliant with this revision. A LAS 1.1 Reader will read LAS 1.2 (without the new enhancements) with no modifications. A detailed change document that provides both an overview of the changes in the specification as well as the motivation behind each change is available from the ASPRS website in the LIDAR committee section. The additions of LAS 1.2 include: • GPS Absolute Time (as well as GPS Week Time) – LAS 1.0 and LAS 1.1 specified GPS “Week Time” only. This meant that GPS time stamps “rolled over” at midnight on Saturday. This makes processing of LIDAR flight lines that span the time reset difficult. LAS 1.2 allows both GPS Week Time and Absolute GPS Time (POSIX) stamps to be used. • Support for ancillary image data on a per point basis. You can now specify Red, Green, Blue image data on a point by point basis. This is encapsulated in two new point record types (type 2 and type 3). LAS FORMAT DEFINITION: The LAS file is intended to contain LIDAR point data records. The data will generally be put into this format from software (e.g. -
Color Management
Color Management hotoshop 5.0 was justifiably praised as a ground- breaking upgrade when it was released in the summer of 1998, although the changes made to the color P management setup were less well received in some quarters. This was because the revised system was perceived to be complex and unnecessary. Bruce Fraser once said of the Photoshop 5.0 color management system ‘it’s push-button simple, as long as you know which of the 60 or so buttons to push!’ Attitudes have changed since then (as has the interface) and it is fair to say that most people working today in the pre-press industry are now using ICC color profile managed workflows. The aim of this chapter is to introduce the basic concepts of color management before looking at the color management interface in Photoshop and the various color management settings. 1 Color management Adobe Photoshop CS6 for Photographers: www.photoshopforphotographers.com The need for color management An advertising agency art buyer was once invited to address a meeting of photographers. The chair, Mike Laye, suggested we could ask him anything we wanted, except ‘Would you like to see my book?’ And if he had already seen your book, we couldn’t ask him why he hadn’t called it back in again. And if he had called it in again we were not allowed to ask why we didn’t get the job. And finally, if we did get the job we were absolutely forbidden to ask why the color in the printed ad looked nothing like the original photograph! That in a nutshell is a problem which has bugged many of us throughout our working lives, and it is one which will be familiar to anyone who has ever experienced the difficulty of matching colors on a computer display with the original or a printed output. -

Adobe's Extensible Metadata Platform (XMP): Background [DRAFT -- Caroline Arms, 2011-11-30]
Adobe's Extensible Metadata Platform (XMP): Background [DRAFT -- Caroline Arms, 2011-11-30] Contents • Introduction • Adobe's XMP Toolkits • Links to Adobe Web Pages on XMP Adoption • Appendix A: Mapping of PDF Document Info (basic metadata) to XMP properties • Appendix B: Software applications that can read or write XMP metadata in PDFs • Appendix C: Creating Custom Info Panels for embedding XMP metadata Introduction Adobe's XMP (Extensible Metadata Platform: http://www.adobe.com/products/xmp/) is a mechanism for embedding metadata into content files. For example. an XMP "packet" can be embedded in PDF documents, in HTML and in image files such as TIFF and JPEG2000 as well as Adobe's own PSD format native to Photoshop. In September 2011, XMP was approved as an ISO standard.[ ISO 16684-1: Graphic technology -- Extensible metadata platform (XMP) specification -- Part 1: Data model, serialization and core properties] XMP is an application of the XML-based Resource Description Framework (RDF; http://www.w3.org/TR/2004/REC-rdf-primer-20040210/), which is a generic way to encode metadata from any scheme. RDF is designed for it to be easy to use elements from any namespace. An important application area is in publication workflows, particularly to support submission of pictures and advertisements for inclusion in publications. The use of RDF allows elements from different schemes (e.g., EXIF and IPTC for photographs) to be held in a common framework during processing workflows. There are two ways to get XMP metadata into PDF documents: • manually via a customized File Info panel (or equivalent for products from vendors other than Adobe). -

Digital Backgrounds Using GIMP
Digital Backgrounds using GIMP GIMP is a free image editing program that rivals the functions of the basic versions of industry leaders such as Adobe Photoshop and Corel Paint Shop Pro. For information on which image editing program is best for your needs, please refer to our website, digital-photo- backgrounds.com in the FAQ section. This tutorial was created to teach you, step-by-step, how to remove a subject (person or item) from its original background and place it onto a Foto*Fun Digital Background. Upon completing this tutorial, you will have the skills to create realistic portraits plus photographic collages and other useful functions. If you have any difficulties with any particular step in the process, feel free to contact us anytime at digital-photo-backgrounds.com. How to read this tutorial It is recommended that you use your own image when following the instructions. However, one has been provided for you in the folder entitled "Tutorial Images". This tutorial uses screenshots to visually show you each step of the process. Each step will be numbered which refers to a number within the screenshot image to indicate the location of the function or tool being described in that particular step. Written instructions are first and refer to the following screenshot image. Keyboard shortcuts are shown after most of the described functions and are in parentheses as in the following example (ctrl+T); which would indicate that the "ctrl" key and the letter "T" key should be pressed at the same time. These are keyboard shortcuts and can be used in place of the described procedure; not in addition to the described procedure. -
