I may have missed a step. I can't seem to get this to work. I was really hoping it would since I haven't managed to get it working any other way either.

It's a very old topic and an old plugin.
Thanks to little progress in Python learning, I've simplified the plugin a little by reducing 5 Steps to one.

Poincare disc Ver. 2

Still only for Windows and Gimp 32bit.

Annex contains:
- poincare.exe
- FreeImage.dll
- poincare.py
- mask.txt
- Notepad2.exe
- doc (description parameters.pdf)
- COPYING licenses GPL

In menu Gimp: Filters -> Render -> Poincare disc...

Everything in the Poincare catalog which after unpacking should be placed in the plug-ins catalog.

After launching the plugin, the mask.txt file will open in Notepad2 and here, in addition to the parameters, you must edit (once) lines 7 and 8 by entering the correct path to the Poincare location, e.g .:

Code: Select all

infile = "c:\Users\YOR NAME\AppData\Roaming\GIMP\2.10\plug-ins\Poincare\image_orig.jpg"
outfile = "c:\Users\YOR NAME\AppData\Roaming\GIMP\2.10\plug-ins\Poincare\image_mask.jpg"

or for the portable version:

Code: Select all

infile = "d:\GIMP-2.10.12_Portable-32bit-Win-V2\Preferences\plug-ins\Poincare\image_orig.jpg"
outfile = "d:\GIMP-2.10.12_Portable-32bit-Win-V2\Preferences\plug-ins\Poincare\image_mask.jpg"

(image_orig.jpg and image_mask.jpg will be created from the active layer by the plugin in the Poincare directory.

While the plugin is running, the Poincare window will appear (do not close it) - it will close itself after rendering.

I would like to add two more information:

- after editing mask.txt, save the changes and close the notepad,
- if "Add original image to layer mask" = Yes, the image name will change from Untitled to Image_orig.jpg.

Why?
This is a small convenience if you want to design Poincare from scratch (yes - Lylejk method).

In brief:
- select the black color and remove,
- invert the selection and remove,
- delete the alpha channel,
- paint your own design in the active selection,
- export as image_orig.jpg (and Gimp should find the save directory),
- run the plugin.

Brings back some great memories, MareroQ. Just wish Bill would have posted that update; oh well.
