Description
I have received a sample image encoded in JPEG-LS that cannot be decoded with DCMTK.
- dcmdjpls reports an error
- the old experimental implementation based on HP LOCO hangs while decoding
The image apparently comes from a PACS installation at a veterinary hospital.
The image can be decoded and displayed using the PACS viewer from J4CARE.
We should check whether this is a fault in the image or a bug in the JPEG-LS
decoder, and whether it would be easily possible to add a workaround for this
bug since apparently such images are used somewhere in the field.
The sample image (compressed and decoded by J4CARE) is available in
