I have this character I want to remove.
The interior of the character was generated using a known gradient map.
I can remove the character using content aware fill, but that does not take into account the information from the interior of the text. How can I reconstruct the background? Can the gradient map information be used to have something like an inverse gradient map?
My idea is to map the colors back to their original luminosity value, and do a content aware fill with a color blending mode, but I don't know how that can be done.
