Hello, everybody knows that gradient map tool works slowly in Krita and that gets in the way of actually using it.
However it seems that the nearest and dither algorithms work really snappy and almost immediately. So what if Krita used the nearest algorithm to make a quick and dirty preview of what it’s going to look like and then updating in the “BLEND” mode to give me the quality result? Picture related, this was generated in real time almost immediatelly.
What I’m suggesting is:
-user tweaks a gradient map for the image
-Krita immediately samples like 10 points from the gradient
-generates a quick preview image with the “nearest algorithm”
-user knows what the image is going to look like and can see what further tweaks are needed
Currently the gradient maps take 10 to 30 seconds to update on a modern overclocked machine and that just breaks the WYSIWYG workflow. Having to spend entire minutes to tweak a single gradient for a part of an image is a real hindrance.
