On my website I apply SVG filters to black and white images.
The effect is a multitone effect achieved by gradient mapping the black and white image with feColorMatrix.
Normally I use black and white pictures with a high contrast for a better multitone effect, but sometimes still doesn't look good enough, so I might need to adjust other parameters then contrast.
What I want is to open a black and white image in Gimp, import my multitone svg filter and apply it to the image as a layer or otherwise so I can see the effect (I don't know if this is possible), and while the effect is on, change the contrast and other parameters of the black and white image to see the output with the filter on...
Any recommendations how to achieve this in Gimp (or in other software)?
I am not sure that Gimp can load an .svg file as a layer, and render the filter on the image just like browsers do.
