GIF
Developed by
Unisys, GIF is a flexible image format which produces small image
sizes and maintains good overall quality.
The GIF format is one of the most popular image formats used on the
Internet. GIF images are normally used for logos, shapes and icons.
The format is based on the lossless LZW compression algorithm and is
superb for compressing large image areas of the same color. Another
important feature of GIF is that it supports animation.
However,
since GIF supports a maximum of 256 colors, it is not suitable for
graphics which have long stretches of continuous-tone in them (for
example, photographs). The number of colors can be reduced in order
to reduce the file size. Anti-aliasing should not be used within GIF
images as the GIF format does not implement these features
efficiently.
