Hidden Art of Unclamping jxlart Artworks
Background Story
On my post about JPEG XL color analysis I mentioned that JXL stores lossy XYB in absolute, float values that can be requested during decoding process by calling pixel format data_type as JXL_TYPE_FLOAT, where out-of-gamut colors are represented with negative values.
I was recently encouraged by Amyspark from Krita to write my python Color Gamut Plotter to something native, like Qt or web-based. As I also doing hacks and sometimes contributing to Krita as well, I took the Qt path as a base. Furthermore, I'm still more comfortable coding with C/C++ rather than JS, might as well training more with Qt~ :3
