RE: Engraving Lines - an error occurred - Kevin - 12-17-2020
Why are we ignoring the fact that when entered manually in the console plug_in_gauss_rle2 generated an error.
Can you do Filters>>Blur>>Gaussian Blur without error?
Can you do Filters>>Generic>>GEGL Graph and try gaussian-blur?

Kelvin,
Although I never used this option before - GEGL graph, and I was scared by the huge text that was on the screen (see below), which I didn't try to understand for the moment.

And the Gaussian blur in Filters - Blur - Gaussian Blur I use it directly and I never had any problems with it.

Thank you for your help!
RE: Engraving Lines - an error occurred - Ofnuts - 12-17-2020
In the sequence of instruction in post #4, what happens if your replace
Code:
pdb.plug_in_gauss_rle2(image,layer,0.,0.)Code:
pdb.plug_in_gauss_rle2(image,layer,1.,1.)In other words, if you attempt to have some blur? What happens if you add some blur in the OEL dialog, for instance a value of 2.0?
RE: Engraving Lines - an error occurred - Krikor - 12-17-2020
No messages this time. (Is that a good sign?)

Sorry, I don't know what OEL dialog would be.
I tried searching on google but found no answers.
What I did, and I don't know if it makes any sense, was to type the text:
gaussian-blur std-dev-x = 2rel std-dev-y = 2rel inside the GEGL graph window.
This worked, as shown in the image below that shows the preview of the applied command.

With a value of 2, it looked like a 200 blur, so I tried it with .02. Perhaps there is some logic to this.[attachment=5364]

OEL: ofn-engraving-lines .Anyway, given your first try , it seems that the gaussian plug-in no longer likes to be called with a 0 value, so that's just a quick fix. Note that you get better results with a blur anyway, the actual definition of the final image is the distance between two paths.

I thought this was an impossible mission ...
But with the update the plugin is running without errors!
For now only a few tests with the Line Thickness option, still nothing with the Dashes option, but I am confident this time.
Now it's time to play around with the new plugin!

To all who tried to solve this problem, thank you very much for your help!
