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. -

Why ODF?” - the Importance of Opendocument Format for Governments
“Why ODF?” - The Importance of OpenDocument Format for Governments Documents are the life blood of modern governments and their citizens. Governments use documents to capture knowledge, store critical information, coordinate activities, measure results, and communicate across departments and with businesses and citizens. Increasingly documents are moving from paper to electronic form. To adapt to ever-changing technology and business processes, governments need assurance that they can access, retrieve and use critical records, now and in the future. OpenDocument Format (ODF) addresses these issues by standardizing file formats to give governments true control over their documents. Governments using applications that support ODF gain increased efficiencies, more flexibility and greater technology choice, leading to enhanced capability to communicate with and serve the public. ODF is the ISO Approved International Open Standard for File Formats ODF is the only open standard for office applications, and it is completely vendor neutral. Developed through a transparent, multi-vendor/multi-stakeholder process at OASIS (Organization for the Advancement of Structured Information Standards), it is an open, XML- based document file format for displaying, storing and editing office documents, such as spreadsheets, charts, and presentations. It is available for implementation and use free from any licensing, royalty payments, or other restrictions. In May 2006, it was approved unanimously as an International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) standard. Governments and Businesses are Embracing ODF The promotion and usage of ODF is growing rapidly, demonstrating the global need for control and choice in document applications. For example, many enlightened governments across the globe are making policy decisions to move to ODF. -

The design of the VOD system is based on the process and location of its three basic contents, which are: the server, network configuration and clients. The clients are varied from numerous approaches, battery capacities, involving screen resolutions, capabilities and decoder features (frame rates, spatial dimensions and coding standards). The up-to-date systems deliver VOD services through to several devices by utilising the content of a single coded video without taking into account various features and platforms of a device, such as WMV9, 3GPP2 codec, H.264, FLV, MPEG-1 and XVID. This limitation only provides existing services to particular devices that are only able to play with a few certain videos. Multiple video codecs are stored by VOD systems store for a similar video into the storage server. The problems caused by the bandwidth overhead arise once the layers of a video are produced. -

What Resolution Should Your Images Be?
What Resolution Should Your Images Be? The best way to determine the optimum resolution is to think about the final use of your images. For publication you’ll need the highest resolution, for desktop printing lower, and for web or classroom use, lower still. The following table is a general guide; detailed explanations follow. Use Pixel Size Resolution Preferred Approx. File File Format Size Projected in class About 1024 pixels wide 102 DPI JPEG 300–600 K for a horizontal image; or 768 pixels high for a vertical one Web site About 400–600 pixels 72 DPI JPEG 20–200 K wide for a large image; 100–200 for a thumbnail image Printed in a book Multiply intended print 300 DPI EPS or TIFF 6–10 MB or art magazine size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1800 x 1200 pixels. Printed on a Multiply intended print 200 DPI EPS or TIFF 2-3 MB laserwriter size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1200 x 800 pixels.

How to Exploit the Transferability of Learned Image Compression to Conventional Codecs
How to Exploit the Transferability of Learned Image Compression to Conventional Codecs Jan P.

The GIF That Keeps on Giving: Assignment Design with Looped Animations
The GIF that Keeps on Giving: Assignment Design with Looped Animations http://bit.ly/gifgive While an older format (created in 1987), GIFs (Graphics Interchange Format) have experienced a resurgence in popularity and use in the past decade. Due to the recent proliferation of digital platforms that host GIFs, the format as a means of communication and as an act of composition has become naturalized and therefore invisible. The rise in their popularity makes GIFs important for scholars of digital literacy and composition to understand and utilize in their teaching and research. We argue that their playful nature, ease of use, and delivery opens GIFs up for new avenues of research, inquiry, and analysis. As such, GIFs can be meaningfully incorporated into the composition classroom as critical components of assignment design and the feedback process. In this mini-workshop, we will introduce participants to pre-existing examples of GIF assignments we have used in courses, discuss avenues for pedagogical research, guide participants in the creation of new GIFs, and facilitate participants’ efforts to design assignments that use GIFs.

Download Media Player Codec Pack Version 4.1 Media Player Codec Pack
download media player codec pack version 4.1 Media Player Codec Pack. Description: In Microsoft Windows 10 it is not possible to set all file associations using an installer. Microsoft chose to block changes of file associations with the introduction of their Zune players. Third party codecs are also blocked in some instances, preventing some files from playing in the Zune players. A simple workaround for this problem is to switch playback of video and music files to Windows Media Player manually. In start menu click on the "Settings". In the "Windows Settings" window click on "System". On the "System" pane click on "Default apps". On the "Choose default applications" pane click on "Films & TV" under "Video Player". On the "Choose an application" pop up menu click on "Windows Media Player" to set Windows Media Player as the default player for video files. Footnote: The same method can be used to apply file associations for music, by simply clicking on "Groove Music" under "Media Player" instead of changing Video Player in step 4. Media Player Codec Pack Plus. Codec's Explained: A codec is a piece of software on either a device or computer capable of encoding and/or decoding video and/or audio data from files, streams and broadcasts. The word Codec is a portmanteau of ' co mpressor- dec ompressor' Compression types that you will be able to play include: x264 | x265 | h.265 | HEVC | 10bit x265 | 10bit x264 | AVCHD | AVC DivX | XviD | MP4 | MPEG4 | MPEG2 and many more.
