JPEG compression algorithm?

Hi,
Earlier, I purchased your IPP version 4.1 including JPEG compression. From your documentation, it is pretty hard to figure out which algorithm is being used. How does your JPEG code relate to the DICOM methods identified as follows:
1.2.840.10008.1.2.4.50 (baseline),
1.2.840.10008.1.2.4.51 2,4 extended,
1.2.840.10008.1.2.4.57 14 lossless NH
1.2.840.10008.1.2.4.70.
Can your code be used to read/write images according the above UIDs?

Hello,

IPP version 4.1 is considered as pretty old nowadays. It was released in September 2004! Please note that the latest version is IPP 5.3 and the next version, IPP 6.0 beta will became available in few weeks.

I recommend you to take a look on IPP JPEGView sample, which is able to read DICOM images with JPEG lossy baseline, lossy extended (12-bit), lossless compression modes (up to 16-bit), JPEG2000 with lossy and lossless compression modes and RLE compression.

Regards,
Vladimir
