- Here's the deal on GIF support in Fastgraph.
-
- We have supported both the creation and display of GIF files in
- Fastgraph since May of 1993. We supported this file format, in
- part, because we relied on the promise by CompuServe that the
- file format is royalty free. CompuServe claims the copyright
- on the GIF file format, and they said we could all use it, as
- long as we mentioned GIF in the documentation, which we did.
-
- What CompuServe neglected to tell us is, Unisys claims a patent
- on the LZW compression algorithm, which is a cornerstone of the
- GIF format. Now Unisys wants royalties on GIF files. These royalties
- will not be collected from users, but from developers of programs
- that encode or decode GIF files. In other words, if you use GIF
- files in your programs, you will owe a royalty to Unisys.
-
- CompuServe has apparently known about this for at least two years,
- but they only bothered to tell us about it 3 weeks ago.
-
- There is some effort in the CompuServe GRAPHSUP forum to both save the
- GIF file format, and to devise a new file format. The GRAPHSUP forum
- is part of the "Go Graphics Group", a CompuServe contractor group
- that apparently makes a nice profit from the continuous download of
- girly GIFs.
-
- The Go Graphics Group is the originator of the GIF file spec, and
- they have set aside a special section (section 19) for discussion
- of the Unisys royalty issue. I have stated plainly my displeasure
- with their handling of this matter in that section. I have also
- offered some opinions on that girly GIF thing.
-
- It appears that we will have no choice but to remove GIF support
- >from Fastgraph. We have always promised our customers a royalty
- free product, and we can not in good conscience support a file
- format on which a royalty is required. If a new file format arises
- to replace GIF, we will support it in Fastgraph, and make that
- support available to our customers in a free downloadable patch
- file.
-
- Fastgraph customers who currently have applications that depend
- on GIF support should contact our office if you have questions about
- continued support. We will do everything we can to help you, including
- supplying you with the GIF code that will be removed from Fastgraph.
-
- If you have a commercial application that reads or writes GIF files,
- Unisys probably expects you to contact them about paying a royalty.
- If there is any possibility of replacing GIF with PCX or other file
- format, I suggest you do it.
-
- We deeply regret the inconvenience this is going to cause our
- customers. If you have questions or comments about the way this
- has been handled, I suggest you log onto CompuServe, "GO GRAPHSUP"
- and let your opinions be heard.
