Hi Gerel.
Hi, I'm close to start this task. As noted on the task summary
there are two possible libraries we can use to implement this
filter. So, I wrote a review on each aspect I considered that was
needed.
Many thanks for working out this nice report.
Licence
----------
## OpenJPEG
BSD Licence.
## Jasper
Jasper Licence (based on MIT licence).
Both licenses are GPLv3 compatible.
## OpenJPEG
Not specified, though the source tree contains libs/libtiff and
libs/freeimage
directories.
We need to check the licenses of any third party software distributed
with OpenJPEG. They may be GPL-incompatible.
## Jasper
For JPEG support needs the IJG library. For jiv (image viewer)
needs GLUT.
Same there.
Installation
-----------------
## OpenJPEG
Makefile (seems they use CMake)
I lightly tried to cross compile the library with mingw32 without
success.
"Unlike JasPer, another open-source JPEG 2000 implementation, OpenJPEG fully
respects the JPEG 2000 specification and can compress/decompress lossless
16-bit
images."
Even if jasper doesn't implement the full OpenJPEG standard, it would
be suitable for use in libgnupdf if it covers our needs. Please check
in the PDF specification.
