convert from dicom (dcm) to jpeg

[wchang615]

Dear All,

For some reasons that when I convert a dicom (.dcm) file to .jpg, I don't see the picture except showing a blank white picture. Is there a set of proper switches that I need to use?

Any helps would be greatly appreciated.

Best,

FYI:
Seems like the later version (6.5.0) has fixed the dicom problem.
I can now convert from dicom to jpeg and see the picture.

Dear All,

Can somebody confirm that ImageMagick still only supports depth 8 (as default) in jpeg?
Is there any way to supports 12, 16, or even 24?

BTE: if I want to use jpeg lossless, how can I do that?

What is your IM environment? Is it Q8 or Q16? If the latter, you should get 16-bits per channel. Use -depth 8 to force to 8-bits per channel.
