Ultra HDR is a true HDR image format, and is backcompatible. libultrahdr is the reference codec for the Ultra HDR format. The codecs that support the format can render the HDR intent of the image on HDR displays; other codecs can still decode and display the SDR intent of the image.

add gamut space conversions in sample app. #238

Closed ram-mohan closed 1 month ago

ram-mohan commented 1 month ago

If hdr intent and sdr intent are of different gamut space, during psnr computations it may be required to do gamut conversions. The logic necessary for the same is added.

Test: ./ultrahdr_app
