GIF (Graphic Interchange Format) is a common format for image files, especially suitable for images containing
large areas of the same color. GIF format files of simple images are often smaller than the same file would be if stored
in JPEG format, but GIF format does not store photographic images as well as JPEG. Because GIF files contain a maximum of 256
colors, this file format is ideal for simple graphics with minimal shading or color variation. That is why Graphics
Interchange Format is the most common format for graphic images on the Internet. This highly-compressed format is used to
display 2-dimensional raster images. A newer version, GIF 89a allows for an animated GIF, which is a short sequence of
images within a single GIF file. GIF can do more than displaying pictures one after another, such as:
- Specify a transparent background
- Specify how long a frame is to be displayed
- Use a partial frame to reduce the file size, for example a frame contains only the next move of the eyes.
A major limitation of GIF is that it supports only 256 colors. You may be disappointed to see that a 24 bit color picture
you produced looks so bad once you have converted it into a GIF file. One solution for this is that you create the
picture with only 256 colors. This way you have control on the final look and feel of the picture.
