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 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.

Understanding Image Formats and When to Use Them
Understanding Image Formats And When to Use Them Are you familiar with the extensions after your images? There are so many image formats that it’s so easy to get confused! File extensions like .jpeg, .bmp, .gif, and more can be seen after an image’s file name. Most of us disregard it, thinking there is no significance regarding these image formats. These are all different and not cross‐ compatible. These image formats have their own pros and cons. They were created for specific, yet different purposes. What’s the difference, and when is each format appropriate to use? Every graphic you see online is an image file. Most everything you see printed on paper, plastic or a t‐shirt came from an image file. These files come in a variety of formats, and each is optimized for a specific use. Using the right type for the right job means your design will come out picture perfect and just how you intended. The wrong format could mean a bad print or a poor web image, a giant download or a missing graphic in an email Most image files fit into one of two general categories—raster files and vector files—and each category has its own specific uses. This breakdown isn’t perfect. For example, certain formats can actually contain elements of both types. But this is a good place to start when thinking about which format to use for your projects. Raster Images Raster images are made up of a set grid of dots called pixels where each pixel is assigned a color. -

UNIVERSITAS INTERNASIONAL BATAM Faculty of Computer Science Department of Information Systems Odd Semester 2019/2020 DESIGN AND DEVELOPMENT OF A GIF AND APNG MANIPULATION DESKTOP APPLICATION Andreas Pangestu NPM: 1631081 ABSTRACT The development of computer systems worldwide pushes the development of animated image formats. Animated images are a general and inseparable element of the internet. Aside from being a form of sharable content across computer users, animated images are one of the prominent forms of culture and communication in the internet. One of the digital image formats that supports animation is the GIF format, which by now, dominates a major proportion of all of the animated images present on the internet. The popularity of the GIF format is derived from its practicality. This practicality however comes with a trade-off in image quality. It only supports a range of 256 colors with optional full transparency. Another animated image format is called APNG, which in essence, is a PNG image but contains more than 1 image frame within it, effectively making it an animated image. APNG is superior in terms of image quality when compared to GIF, because it has the quality of a normal static PNG image. It supports 24-bit RGB colors or 32-bit RGBA colors, with an alpha channel that supports partial and/or full transparency. Despite its better quality, the GIF format is more popular and ubiquitous because of the severe lack of APNG manipulating tools on the internet. The author of this thesis will develop a cross-platform desktop GIF and APNG manipulation application. It supports 3 main features: creation of GIF and APNG images using image sequences, splitting of GIF and APNG images into image sequences, and modification of the attributes of GIF and APNG images. -
