I like to apply LUT to image, very much like we do in photoshop Layer > New Adjustment Layer > Color Lookup but couldn't find documentation on how to do it libgd.
Is it possible to apply lookup table (LUT) using libgd?
I could find one function here but it does not have any description so not sure if that's the correct function
https://libgd.github.io/manuals/2.3.3/files/gd_color_map-c.html
Thanks
