2013-01-05 09:36:57 -0600 asked a question Patches I would like to introduce - need advice

In order to use some externally supplied files, I wrote the following patches :
1. Ability to load TIFF with alpha channel (today the 4th channel is stripped).
2. JPEG with quality 100 will have chroma subsampling of 1x1 instead of current 2x2 (like photoshop uses).
3. Ability to load TIFF with JPEG compression (simply configure libtiff to include it and reference the corresponding libjpeg).

The problem is that 1 and 3 requires OpenCV to update libjpeg to the latest version (8).

Is it in the scope of something doable?
