Test: ./ultrahdr_unit_test Change-Id: I4d42d152db2d1c0ddbaf797505fb117d52c7d2bf
- Add support for more sampling formats - RGB jpeg encode now defaults to 444 sampling format instead of 420 - For unaligned blocks memset chroma planes to 128 to...
Initial versions supports decoding images with subsampling factor 4:2:0. This changes broadens the support. Test: ./ultrahdr_unit_test Test: ./ultrahdr_dec_fuzzer
- luminance function for p3 gamut is using weights of DCI P3 instead of Display P3. This is corrected. Accordingly, the gamut conversions involving Display P3 are updated. - Increased...
add API to set mastering display, target display peak brightness
- validate gainmap metadata during decoding before using it - fix issues in gainmap weight factor computation during applyGainMap
Also simplify sdr rgb jpeg encoding.
- update tone mapping to reflect the implementation in api-0. - update the icc profile to output results in xyz D50 instead of Lab. - update the icc profile to...
Gain map technology offers a way to create an image (henceforth referred as derived image) from one base input image and a secondary input image called as a gainmap input...
