Unless I get help or learn more this is my final filter. There are things I know GEGL can do but I don't know how to make a GUI of it.
I hope everybody enjoyed my filters and I hope other GEGL authors show up and make a difference. There is a high chance that @MareroQ will chime in with a Windows build. So all you need to do is put the dll or .so files in /gegl-0.4/plug-ins

Version for Gimp-2.10.30 Win 64 Bit attached.
Place the file in Gegl plugins in a directory: ... \lib\gegl-0.4\

In menu Tools➤GEGL Operation➤Edge Extraction

I am experimenting with edge sobel and I realize it does a better job. there is a high chance I will swap edge-neon with edge-sobel.


Poor MareroQ will have to recompile for Windows.

Okay the algorithm has been swapped with edge sobel. This made a considerable difference in quality. If I knew more I could include all five edge detection algorithms gimp has.

The filter had an update that changed the algorithm.

Why don't other users who can compile it want to do it?
New version in attachment.

Perhaps because we haven't any idea how to go about compiling it.

Maybe you could write a guide to compiling GEGL plugins, then maybe you'll get some assistance.

Hi Kevin.

The question was for those who can (i know how), but do not want to be active.
I do not want to persuade anyone to publish - I am only interested in the reason for such a decision (I know, but only for myself ).
Sufficient information for compilation is provided in the file source link.

Filter got an update and now has a blur that goes up to 6.5 (originally it stopped at 3) and it can change line colors. This goes good with blend modes like softlight and hslcolor.

Update version for Gimp-2.10.30/32 Win 64 bit in attachment.
