[Insight-users] GDCM update / JPEG2000 (OpenJPEG)

[Mathieu Malaterre]

Hello,

	I have a minor technical issue. Currently GDCM uses the (patched)jpeg 
from the Utilities directory to be able to decompress JPEG lossy and 
lossless file. I was asked to update gdcm 1.0 to gdcm 1.2. In gdcm 1.2 
we have added support for JPEG2000 encoded file. This is for now very 
rare IMHO. So my question is:

- Do I add support for JPEG2000 in ITK, knowing that it will add a new 
library to ITK (~373k line of code). Code for the library can be found 
at http://www.openjpeg.org (*)

- If yes, do I make it an available library just like png or tiff, or do 
I keep it encapsulated into GDCM ?

- If not I can still update to gdcm 1.2 which will still add a lot of 
new features lacking in gdcm 1.0. I'll simply change the cmakelists.txt 
to not include JPEG2000 code.

Comments welcome,
Mathieu
(*) At some point during the development process jasper was considered 
and used in GDCM to decompress JPEG2000 DICOM image. But due to a major 
decompression problem for 16bits lossless image the support was 
discontinued in favor of the lighter openjpeg implementation from 
Communications and Remote Sensing Lab (TELE).
