![]() ![]() This used to be really important.įor something like a photo, however, this system breaks down. The image data, rather than specify colors directly, just points you to a coordinate on the palette.įor something like old video-game art, where there is a limited number of colors, this method works great! You can store an image in very little space and send it over the internet very quickly. The palette, however, is a separate image–sort of like a rainbow–containing all of the colors that can appear in the image. The image data is what we've looked at earlier, numbers that tell you about the colors in each pixel. A GIF has two parts–the image data, and the palette. Rather than specify the amount of each color directly, they use a different method. See, GIF is an older format, and it operates in a different way. That means that black is still and there are ~17 million possible colors! This system, called "true color", is the basis for almost every image format out there.Īlmost every one, that is, except GIF. That obviously won't do, as the human eye can pick out a lot more than 8 colors.įor their wide range of colors, virtually all modern image formats use 256 possible colors for red, green, and blue each. What if it was a white pixel instead of a black one? Well, white means the maximum amount of each color, so we could write our white-pixel-imageīut then we only have 8 possible colors that our image format can describe! for red, for yellow, for green and so forth. With a very basic image format, a 1-pixel black image could be written like this.įor the zero-amount of red, green, and blue in the one pixel of that image. Specifically, an image format is an algorithm for telling you the amount of red, blue, and green in each square picture-element of a given image. An image format is an algorithm which allows you to convert a picture into numbers that the computer can store. GIF is an image format, like PNG or JPEG or TIFF. r/FreeCAD FOSS Parametrical CAD/CAM /r/scribus Desktop Publishing Darktable FOSS tool for photographersīy way of explanation, here's a long lecture, skip to the TL DR if things bore you. r/gmic FOSS image processing framework /r/inkscape Vector-based graphic editor /r/blender 3D modeling, animation, & rendering /r/mypaint painting for digital painters /r/darktable/ photo editing software /r/krita digital painting application /r/synfig FOSS 2D Animation /r/FOSSPhotography Folks who use all the above /r/libredesign changing the paradigm Other Links of Interest Outreach through well written tutorials, presentation etc.Help test and triage bugs in the bugtracker.Alexander Prokoudine - /u/prokoudine ( LibreArts Founder) ( patreon) Ways to Assist GIMP.YouTube Channel spamming will not be tolerated.CSS help provided by /u/Cheesydude All about the GNU Image Manipulation Program ![]()
