I think there are no severe problems that should keep the ASF from producing a full implementation. There is some interesting information on Wikipedia: http://en.wikipedia.org/wiki/JPEG#Potential_patent_issues
In terms of full support, the rest of the above Wiki page should give an idea what kinds of steps are involved in encoding and decoding a JPEG image. Obviously, this thing has to be as fast as possible. Harmony used libjpeg (in C) for the JPEG codec: http://svn.apache.org/repos/asf/harmony/enhanced/classlib/trunk/modules/imageio/src/main/native/jpegencoder Of course, we could do it the same way, but a plain Java implementation would really be great because there are no problems with different platforms even if that means a possible, little performance impact. At any rate, I guess it's quite a bit of work. Anyway, the decoder is probably more important than the encoder. Well, at least to me. ;-) On 08.04.2008 11:35:07 Carsten Ziegeler wrote: > Just curious, what needs to be done to get full jpeg support?
