Bug #314
closed
DcmElement::getUncompressedFrameSize() funktioniert nur bei BitsAllocated = n*8
100%
Description
Wenn BitsAllocated kein Vielfaches von 8 ist, dann stimmt die berechnete Frame-Größe insofern nicht, als dass in ''DcmPixelData::getUncompressedFrame()'' bei unkomprimierten Bildern ein falsches Start-Offset berechnet wird.

It seems to me that this indeed fixes the bug; the strange thing is that the commit was in May 2009, but the Redmine entry was created in November 2009.

I checked the old "bug list" in the Wiki: the timestamp seems to be correct (which does not clarify the contradiction).
So, we probably need to test the code with an appropriate test file...

I have created a test image with 3 frames and BitsAllocated=24, and image display works just fine. So the commit from 2009 indeed solved this problem. Attached the test file (manually generated starting with a Cabinet test image).
