From David Spencer's Media Spin : Observations about media in Canada
| Today is Thursday May 23, 2013 in Canada.
This is the day that the Lord has made; we will rejoice and be glad in it. (Psalm 118:24)
David Spencer's Media Spin Canada provides information on:
The format uses a palette of up to 256 distinct colors from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for more simple images such as graphics or logos with solid areas of color.
This format is based off of the LZW compression, which removes redundant information from a bitmap and limits the amount of colors used. In other words, instead of defining each pixel’s color, like in the BMP format, GIFs will define one color for several pixels. It will also reduce the number of colors (color palette) saved in the file to only 256 colors or less instead of the normal millions of colors in a BMP. GIFs also have the ability to have transparent backgrounds and animation.
