RT Dose 32 bit Image Compression Failure

Hi,

We have some 32 bit RT Dose Files. As i know, DCMTK compression API's are meant for 8 and 16 bit DICOM files. I have seen DICOM RT support in recent dcmtk snapshot. Can you please confirm that 32 bit RT Dose files compression is supported in the snapshot?

Thanks,
Angad Nath

Re: GSPS Objects(arrow and angle)

Hi,

Thanks for quick reply.

Any idea in which release(or version) you guys are planning to provide this Compound Graphic Objects support.

Is this feature available in latest dcmtk snapshot?

If not, can you please suggest me any work around?

Thanks,
Angad Nath
