DCMTK crashing while trying to display multiple images (tile).

[indrajit]

Hi All,

I am using dcmtk and DICOM Scope code to display multiple DICOM images (from the same series) in a tiled manner (4x4, 3x3, 2x2 etc.). I am basically trying to use the DICOMScope code (and using JNI to communicate with the dcmtk).

In doing so, the JVM is crashing. This is happening whenever I am trying to display more than one image for the first time.

It seems that the crash is occuring at findDisplayArea (). Has someone already faced such a problem? Any help in this regard would be great!

Thanks,
Indrajit

Following is the crash log:

The class DVInterface (which is also used as the main interface between the C++ and the Java part of DICOMscope) does only support a single image at a time. If you want to manage/display multiple images you have to enhance the code accordingly.

I'm going to work on multiple images,
can anybody give an idea.
Should I enhance on dcmtk to display multi image , or enhance on Dicomscope?

IF you have other idea or source code, thanks so much

I appreciate which you all support

thank you

[Jörg Riesmeier]

You probably need to enhance both since the data handling is part of the DCMTK module "dcmpstat".

So I need to learn more, cos I have no experience on dcmtk

thank you
