Hi, Everyone,
This is my first post here, so I hope I'm doing it correctly.
I make drawings of astronomical objects - galaxies,star clusters,planets, etc., through my telescope. After finishing a drawing, I scan it and process it in GIMP. The results are posted online in web sites like CloudyNights.com
There are about 20 steps in the process, so I would like to be able to automate the process. According to the GIMP manual, this can be done in Python.
Here are the steps, after the pencil drawing has been finished:
Scanning:
1. Slide drawing into scanner.
2. Adjust light and shade for grayscale scan.
3. Scan drawing.
4. Remove drawing and repeat above steps for next drawing.
GIMP Processing:
1. Open scanned drawing in GIMP.
2. Invert black and white.
3. Select circle for field of view.
4. Invert circle selection.
5. Use Color Picker tool to determine color of background around selected circle.
6. Use Paint Bucket tool to cover background with selected color.
7. Export modified image and save.
8. Close view.
9. Re-open image and select "New Layer".
10. Select Paintbrush tool (12 - 20px) to place "stars" over the drawn stars on the bottom layer.
11. Return to bottom layer.
12. Use Color Picker tool to select color of field-of-view background.
13. Use Paintbrush tool, at 20px size, to paint over stars on bottom layer.
14. Choice: Return to top layer and use various paintbrush tools to modify or enhance the object (galaxy, star cluster, etc.) OR remain on the bottom layer to use Smudge tol to modify oralter the image.
15. Use Text tool to create title for drawing and descriptive text.
16. Export image, save and close view.
Here is an example of the end result:

I'm a newbie to GIMP scripting, so any recommendations, guidance or assistance will be appreciated!
Thanks,
