gimp (at least the version I have) does not offer gif as an output format when I select save formats. There is a long-standing issue with gif format files. Because Unisys holds a software patent on the method for producing gif files, some programs will not save files in that format to avoid patent infringement claims. The 'display' program (part of ImageMagick) will read jpg and save in gif format. Jim Cunning
I do not know if this is applicable for your application, but you might think about using png. If I recall correctly it has all the features of a gif (plus a few) and none of the patent limitations, also I think the file size is equal and it is lossless. I could be wrong on the last part though. Austin On Sat, Feb 23, 2002 at 09:35:02AM -0800, Jim Cunning wrote:

Yes, and many are using png simply because they don't agree with Unisys trying to hold the computing world hostage with their royalty demands. I have always been competely satisfied with the results saving in png format. *************************************************** Powered by SuSE Linux 7.3 Professional KDE 2.2.1 KMail 1.3.1 This is a Microsoft-free computer Bryan S.

Nope, you're right PNG is technically superior to GIF in _every way_. PNG allows 64-bit images, has much better alpha blending, much better compression (zlib based), and even has 2-dimensional progressive scanning. All that, plus it's not patented and you don't have to pay! How could you lose? -- Karol Pietrzak PGP KeyID: 3A1446A0

Gimp version 1.2.2 that I have will let me save as .gif. It is greyed out in the drop down extension box but if you type in file.gif then it asks if you want to export the image and it works. Although I don't know why you want to save as .gif.

That is correct that some programs won't do it because of the patent. The free Linux version of Compupic is one I know of personally. If you pay the pretty reasonable purchase price (I think around $40, at least that's what it was last time I checked) that covers the cost of the royalties so the paid version will do gifs. In the case of Gimp, however, I have had several versions and never had any problems converting to gif format. Choose "determine file type by extension" and enter a file name something.gif, and it will do it. This would be under File | Save As. *************************************************** Powered by SuSE Linux 7.3 Professional KDE 2.2.1 KMail 1.3.1 This is a Microsoft-free computer Bryan S.

Sure. In file | save as, set it for "determine file type by extension" and give your file name whatever.gif. It will tell you it must be "exported" because of the different format. Go ahead and say OK, and it will give you a gif. *************************************************** Powered by SuSE Linux 7.3 Professional KDE 2.2.1 KMail 1.3.1 This is a Microsoft-free computer Bryan S.

Yes it can convert to gif.
if not what tool is outthere that can do it
ImageMagick. You can either use the program convert from the commandline, or show the image using display and save it as gif. Charles -- The box saids Windows XP or better, so I installed Linux

As others replied already, you might consider `.png' instead of `.gif'. Besides `gimp', which can convert between many formats, I used `convert' from ImageMagick, a combination of tools from `PBMplus', and the `pilfile' utility that comes with the Python Imaging Library. Even if some of the above can produce `.gif' files, they might not produce them in compressed form (as this is not legal to do so, because of patent problems), so the produced `.gif' are not always the best you could hope. I think I vaguely remember having produced `gif' through ImageMagick, and later compressed them through PBMplus, but this was many years ago. Today, I just never produce `.gif', and use `.png' as a portable format. I much appreciate `.png' because it can conveys 8-bit alpha channels (while `.gif' are limited to 1-bit alpha channels - which is rather rough for an approximation). -- François Pinard http://www.iro.umontreal.ca/~pinard
