![]() (They did not want anyone to confuse them for English majors. So they decided to call the images "Channels" which sounds more scientific. 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. 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. Tux Paint is used in schools around the world as a computer literacy drawing activity. Tux Paint is a free, award-winning drawing program for children ages 3 to 12 (for example, preschool and K-6). This means you may download it and install it on as many machines as you wish, copy it for friends and family, and give it to your local schools.

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. 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.
