lossless jpeg supported bit depths

[Vojtech Bubnik]

Hi,
we have to interface our DICOM application with the GE CT, which does generate unusual 15 bit grayscale lossless jpeg images, which is perfectly correct according to the DICOM norm.
I am not sure, if the combination of patched IJG JPEG implementation compiled for 8, 12 and 16 bits could decode this kind of data stream. Could You please give me a hint?
Thanks

The patched IJG JPEG implementation should be able to decode anything between 2 and 16 bits for lossless JPEG, it will just be unable to create a compressed stream with 15 bits/sample (this would be padded to 16).
