uhdr_decompress()

[MajorMurphy]

This comment mentions calling uhdr_decompress()

libultrahdr/ultrahdr_api.h

Line 561 in ccc54ea

* - The program calls uhdr_decompress() to decode uhdr stream. This call would initiate the process

But I didn't find that function in the API header or sample.
Is the comment referencing a deprecated function?

Thanks

Must be an outdated name for uhdr_decode().

The decode API options and examples are listed in the app help:

decode api :

ultrahdr_app -m 1 -j cosmat_1920x1080_hdr.jpg 
ultrahdr_app -m 1 -j cosmat_1920x1080_hdr.jpg -o 3 -O 3
ultrahdr_app -m 1 -j cosmat_1920x1080_hdr.jpg -o 1 -O 5

decoder options :

-j    ultra hdr compressed input resource. 
-o    output transfer function, optional. [0:linear, 1:hlg (default), 2:pq, 3:srgb] 
-O    output color format, optional. [3:rgba8888, 4:rgbahalffloat, 5:rgba1010102 (default)] 
      It should be noted that not all combinations of output color format and output 
      transfer function are supported. 
      srgb output color transfer shall be paired with rgba8888 only. 
      hlg, pq shall be paired with rgba1010102. 
      linear shall be paired with rgbahalffloat. 

common options :

-z    output filename, optional. 
      in encoding mode, default output filename 'out.jpeg'. 
      in decoding mode, default output filename 'outrgb.raw'.

That's what I expected, but glad to have it confirmed. Thanks!

Just to be clear, I'm speculating. I haven't been writing any of this code myself. But given it's in the JSDOC for that function, seems very likely to be the case.
