JPEG Lossless, Non-Hierarchical, First-Order Prediction - decoding fails on MONO

[petr....@gmail.com]

Hi all,

please correct me if I'm wrong, but I thought  JPEG Lossless, Non-Hierarchical, First-Order Prediction can be opened in new version via managed libraries for jpeg (CSJ2K or BitMiracle.LibJpeg.Portable)

I'm using version 3.0.2.1 on RPI MONO. I used Dicom.Core.dll provided for MONO. It process DICOM file (STORE-SCU) well, but it fails decoding image.

Should/can it be decoded on MONO? Do I something wrong?

Thanks for help
Petr

Hi Petr,

Unfortunately,LibJpeg.NET does not support JPEG lossless, so this codec is not included in the Mono build. The two JPEG losless codecs are currently only supported on .NET Framework and Universal Windows Platform.

Hi Anders,

thanks for answer. And just for my curiosity - is there any plan to add this codec to managed LibJpeg.NET or use any other library (if available/exists)?
I do understand loseless JPEG is (very) different to "normal" one.

Thank you

I googled around a little bit and I found your project cscharls. Do you think it could be used here?

Thank you

As confusing as it might be, JPEG-LS (i.e. the charls codec) is not the same as JPEG Lossless, so unfortunately charls is not an option for the JPEG Lossless, Non-Hierarchical, First-Order Prediction transfer syntax.
