[PATCH v2 6/6] wmphoto: Implement WmpDecoder using jxrlib.
Rémi Bernon
rbernon at codeweavers.com
Fri Sep 18 07:50:09 CDT 2020
With only a single frame for now. The jxrlib decoder seems to have some
quirks, and fails called multiple times, so decoding multiple frames
will need a bit of investigation.
Hopefully it will not be required anytime soon.
Signed-off-by: Rémi Bernon <rbernon at codeweavers.com>
---
v2: Split copy_pixels to a separate file and use PARENTSRC to share it
with wmphoto.
Also split the decoded frame to a separate class so we can more
easily support multiple frames in the future -- although the jxrlib
decoder doesn't seem to like being called multiple times.
