DCMJP2K with 3.5.5 git

#1 Post by Olric86 » Sun, 2010-07-25, 12:42

Hi to all!
I just took a look at the git version of DCMTK and, if I understood the changes correctly, it seems that the 3.5.5 version can handle huge multiframes images a little better, isn't ?

My question is, if we have the DCMJP2K module developed for 3.5.4, can we change the CMake files in order to include it in the build or did this module change too ?

Thanks in advance

Hi Olric,

the main support for partial, frame-by-frame reading (especially compressed) of multi-frames into memory is integrated into dcmdata.

However, as you can see in the corresponding changes in the dcmjpeg module, there is some extra work necessary to add this support to a specific compression codec. For our JPEG2000 module, this is not yet done. However, the code changes necessary are analogous to the ones in dcmjpeg and therefore, should be not that difficult and time-consuming. I'm sure we add that on the mid-term.

Best regards,
Michael
