[Insight-developers] ITKv4: openjpeg-v2 update: GDCM

[Mathieu Malaterre]

Hi Luis,

  Good work on OpenJPEG v2 !
  Unfortunately the patch is non-trivial, see the one in GDCM 2.x:

http://gdcm.svn.sf.net/viewvc/gdcm/trunk/Source/MediaStorageAndFileFormat/gdcmJPEG2000Codec.cxx?r1=6931&r2=6942

  If GDCM is updated in the coming days, I would vote against
preparing such large patch, for such little goals (couple of days).
Would it be possible to simply skip the compilation of gdcmJpeg2000
completely ? There will only be one test failing (DICOM+JPEG2000
compression).

HTH
