I like this plug-in, but it is not mine - the credit for it must go to Tim. I have made only small modifications.

@teapot,

Despite spending most of the day on this problem, I have not yet been able to come up with a solution!

Thank you for looking into this. I have just now asked for help here:

Went to Bermuda last year and used G'mic B/W pencil:

OK; got Impressionist plugin to work in GIMP again (have to, from time to time, edit the PSPI.ini file and hope it sticks). Thought I would use my Van Gogh present and then bumped up a notch via G'MIC and a few other things.

@teapot,

Thank you for your efforts in resolving this problem.

This morning I changed to your values - pdb.gimp_drawable_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0.0, 0.0, 0.615, 0.431, 1.0, 1.0]) - the result was almost identical to the 255 based numbers. (Actually with your numbers the colour was slightly more intense. Perhaps from rounding errors in the conversion.)

If we can confirm that the floating-point values work for other people, I will change the plug-in.

@Issabella,
Could you please try the attached version of picture to line art and tell me if it works OK for you.

@teapot,
The attached version uses your values for the histogram, so it should work for you as it does for me.

If this script is OK for the three of us, I will follow it with a cleaned-up and extended version which I am testing today.

Congrats David. I see even better result, I think.
It works great for me. Paper ffff00 as you said.

Dinasset, David and Lyle, Thanks for your outcomes. :clap

David, I have your last version. and the previous one

Issabella,

Many thanks for testing the plug-in.

Now we can have the new version which I have been testing:
1. It now has the option to change the colour of the ink as well as the paper.
2. I have renamed the layers, I hope, to something more meaningful.
3. If there is a selection in the original image, it is removed and saved to a channel.

Here is a silly example from the testing - green ink on blue paper!
