libjpeg

[Maarten Bosma]

Does anyone mind if I import libjpeg for jpg support ? The License is 
not a problem, but the patent might be. Sorry that ask so late (did 
already a vendor import). I asked 2 times on IRC and thought that would 
be enough, but GreatLord convinced me that I have to asked here too.

PS: The size of the files that would go into reactos/lib is 694 KB.

No problem here. JPEG is complex and I doubt we can find a significant smaller implementation.
Which parts are patented and in which countries? Can you disable the parts that is
covered by patents by default like we do with freetype?

Well, it says the patent will expire in 2006.

As far as I know, GIF's patent has already expired, it wouldn't
surprise me if JPEG's will do so, too.

As far as I know the IJPG implementation (that is, the International JPEG 
group) - which is used by MS as well as all GNU systems - is totally free and 
clear. It is covered by something similar to the GPL and, IIRC, all you need 
to do is include a copy of the license and state that you are using the 
license. MS does this and, of course, Linux and BSD and all other OS 
operating systems include all the docs from the source distro as well as, in 
most cases, including the complete source.

The patent will run out in oct 2006
after that I do not see any problem with usinh libjpg or have it in reactos

I think it is fine to bring it in.  A lot of companies think that the 
patent is not right.  And even if it is valid, it is ending soon and in 
the code you can avoid using it by another method.  So... i don't think 
there is not a reason to use it.
