Color function "equalize" is different to earlier versions - Merlin - 08-05-2025
I have been using the “equalize” function to correct images with poor color matching.
Menu: Colors - Automatic - Equalize
Python: t = layer.equalize(False)
This worked well in Gimp version 2.10.38. In Gimp version 3.0.4, the result is different. Based on the histograms, I suspect that this is due to the processing of the images in the linear color space. Unfortunately, the results of version 3.0.4 are significantly worse (too bright), regardless of the format of the source images (integer, float, linear, non-linear).
How can I get the results of the earlier versions back in version 3.0.4?

I wonder if it is a bug ? Probably Ofnuts will know.
Only by trial, looks like the histogram is pushed across to the light side, so maybe this.
(1) Apply Auto -> Equalise
(2) Apply Auto -> Stretch Contrast - with settings as shown.
