Linux and JPEG2000

Post by Andreas »

Hi,

first I'd like to thank you for your excellent software.

Is there any possibility to implement JPEG2000 in the Linux version? I'm asking because there are very few JPEG2000-enabled image viewers for Linux. Actually, I don't know any other than ImageMagick display, which is not very convenient to use.

Are there any licensing issues with JasPer, so that you must implement it as a plug-in in the Windows version? Plug-ins don't seem to be implemented in the Linux version. Or is JasPer too large? If so, you might be interested in OpenJPEG as an alternative:

http://www.openjpeg.org/

OpenJPEG is a 100% BSD-licensed JPEG2000 codec and very small, the shared library is just 150 kB in size. The forum is offline, but the library seems to be maintained and has releases ~ every 6 months.

This is the documentation:

This is the license:

Thank you anyway, Andreas
