There may not be a lawyer behind it, but it is still a license. I realise that for coders thinking of all these pesky legal matters is a nuisance more than anything else, but there are coders on trial for not looking at the legal small print at this very moment. We may not like the laws, but they are the laws nonetheless. Here's the ImageMagick license as the main ImageMagick FTP site lists it: <begin> COPYRIGHT Copyright (C) 2001 ImageMagick Studio, a non-profit organization dedicated to making software imaging solutions freely available.

I'll have to look it up again, but the way I understand it, the ImageMagick license is a free software license, compatible with the GPL. Also, since you are allowed to add extra licenses to the GPL (IIRC, again, I'd have to look it up and am too tired at the mo to wade through the legal mumbo-jumbo), it would perhaps be possible to bring ImageMagick code under the GPL And of course, if we thought we could use some ImageMagick code, we could always ask the authors to also bring the bits of code we need out under the GPL. One is allowed to publish his/her own works under several, differing licenses. >I would not expect that any of the code that is written to >support XCF in ImageMagick would make it way back into Gimp (since it's > really us trying to support things you already do).

This is a license too, although I am not sure you are enough of a legal representative of ImageMagick to supply it. Oh, and IANAL. -- branko collin collin@xxxxxxxxx
