Hi there,

i am currently trying your Trial SDK 8.3.0.

I am interested in it, because i tested your Actions.exe tool and could successfully load a Dicom image with Lossless Jpeg (SOF3).
We are searching for a decompression solution for this data type atm.

Since we have our own dicom parser, i tried to decode the exported jpg image itself via your Library and was not able to.

Loading the pure dicom in your Actions.exe tool also failed.
Again, when i try to load it as encapsulated dicom image, it loads perfectly.

My questions:
1. Do you use different decoding paths for the internal dicom data compared to your common jpeg decompression path?
2. If so: Is it possible to support Sof3 decoding also for you common jpeg path?

I uploaded the test example (.dcm and .jpg) here:

Best regards,

Hi Hugie

In the case of lossless JPEG content in DICOM files, the standard JPEG library is not used (because the process is quite different). So SOF3 is supported in DICOM files (where is sometimes encountered) but not standard JPEG loading (where it is never encountered).
