![]() ![]() (They did not want anyone to confuse them for English majors. So they decided to call the images "Channels" which sounds more scientific. Its an easy way to store 32bpp RGBA images (24bpp true color with full 8bpp alpha transparency), excellent for use in graphics programs like Tux Paint. Its the file format Tux Paint uses to save images, and for its brushes and stamps. Tux Paint is open source to let users look at and change the source code within the terms of the GNU General. Tux is a cross platform app that is available for the most recent operating system releases of Android, Apple Mac, Linux, and Microsoft Windows ( 11, 10, 8.1, 8, 7, Vista, XP) PC devices. ![]() So finally they simply called it by the totally ridiculous name of "Alpha" since that was the first letter of the Geek alphabet and, therefore, the only name they could agree on.Īnd at the same time, they also decided that saying "red image" and "blue image" and "Alpha image" was not digified enough. An extensible file format for the lossless, portable, well-compressed storage of raster images. Tux Paint is a safe tool to download and install. Sadly, being scientists, they could not agree. Then another wanted to call it "Burt" Then another wanted to call it "Kate" and finally one wanted to call it "Christine" for the famous rocket scientist, Christine Latter of Boise, Idaho. One scientist, whose name was "Fred" said he wanted to call it "Fred". compose, or convert bitmap images supporting quite a large number of image formats. And in the 8 bits that are not being used, let's add a gray image which explains how transparent the RGB image is."Įveryone agreed that this was a wonderful idea.īut then someone said, "But what should we call this gray image since it is neither "red" nor "blue" nor "green"? We need a fancier name than "transparency" because that would be too simple. Where does Tux Paint save my drawings Unless you asked Tux Paint to save into a specific location (using the 'savedir' option), Tux Paint saves into a standard location on your local drive: Windows Vista, Windows 8, Windows 10, Windows 11 In the users 'AppData' folder: e.g. To support export of animated GIFs (slideshows), the 'libimagequant' library (from the 'pngquant2' project) is required. Since 32 binary bits is a very convienent word size for most computers (i.e., 4 times 8 binary bits), scientists said, "Let's use all 32 bits for a single pixel since this is very efficient. Here is the scientific logic behind the fourth image in a PNG picture.Įach pixel of a PNG picture (a color picture for the computer) is described by 8 binary bits of red, 8 binary bits of blue and 8 binary bits of green. ![]()
