With my version of GIMP (2.10.2), when I 'export as,' the program will create BMP files with 128 offset-long headers. Is this something new? In the past the headers were only 40 offsets long, filled mostly with 00's.
Reason I ask is that the application I am using (AC3D) wont let me load a texture with a header that long. In the past, the 40 offset-long headers worked like a charm. But all of a sudden my textures won't load. I can even take an older, loadable texture, open it with GIMP and merely save it as a different file name (no other edits), and AC3D will not accept it. But if I merely re-name the file from the file explorer, it works like a charm.
Any help or direction would be deeply appreciated.
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.
My GIMP 2.10 (as well as 2.10.2) on Windows 7 (64bit) does NOT display any histograms on the "Adjust Color Curves". Did I do something wrong? Maybe some obscure setting that I can't find? I think this is important. Hard to imagine it could go unnoticed. What's going on here?
Some tips on setting up Gimp 2.10 on a smaller computer. There are plenty laptops around with 'wxga' 1366x768 px displays.
The demo uses Windows 10, also applicable to Windows 7 and Linux
1. Initial setup of theme and icon theme.
2. Setting up the toolbox icons, hiding icons, moving icons
3. Adjust the Gimp window to fit display.
4. A new default canvas size.
I have been using 2.10 for a week or so, and one thing has started to bother me.
The Transformation tools work very well, don't get me wrong. But for whatever reason, it seems that we have decided to take away the New Window/Dialog Box(which had buttons, sliders, and measuring aspect of the Transformation) and leave ourselves to "guessing" the amount of Transformation a layer takes, compared to previous versions of the software.
For instance, when Rotating a layer, there would be a handy indicator in a new Window telling me how much it has Rotated (by how many degrees). I cannot find this feature in the new version. Example included as an Attachment.
Also, there is no prompt for "OKing" the Transformation anymore. Now, it seems I must select a new Tool after performing the Transformation, and it just happens automatically.
I do not like these changes... is there a way to revert them in this new version, or an option to bring back the Window/Dialog Box?
