http://www.boutell.com/gd/ is the web page of the original author of the
[GIF] creation library GD.   Originally, when [Compuserve] created GIF, the
file format most commonly used included a compression algorithm that was
patented by UNISYS (see [LZW]).  When UNISYS began enforcing their patent,
work on free GIF creation libraries shifted from generating compressed
files using the patented algorithm to creating image files uncompressed.

[LV] libgd 2.0.33 (as of 2004) works with gifs, jpegs, and pngs, as well as other formats.


'''Bullonya.''' It is a bad thing.  Click on the second link below and get libgd with gif, [jpeg], and [png] support.  [LV] Of course, using software that makes use of the [LZW] patent without paying [Unisys] may result in your company being named in a lawsuit.  It's your nickel.

(this link was unannotated before, [FW] adds:) [fly] is a method of generating images "on the fly" using GD, and allows for command line access (via, say, Tcl's [exec]) so it can be used by just about any language with shell access and I/O.  This is, as far as I know, the only way of using GD from Tcl.
