Let's say I have a file that is 4000 x 4000.
I edit and want to keep a master file.

I now want to save a version that is 1000 x 1000 as  a JPG.
Is there a keyboard shortcut to do this?

Do I have to:

- save
- reduce size
- export as JPG
- close file and be careful not to save (which I've done many times in Photoshop).
(or i can undo - but still same problem)

Also... another question...
What automation tools are there... what can I automate? Just looking for a link to read more.

Also... how do I drag the window around. If no tool is selected, I can't drag around - I normally press the space bar and then move the mouse around. I can't find the same tool you have in other graphic editors. 

Thanks.

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.

Great resource for grunging up your artwork !

Either use the texture as a layermask or as a layer with a suitable layermode.

I've clicked around loads and can't see how to do

What am I missing?

Not sure about using pen tool.

I click and make several dots... all OK.

But then... if I want to delete a dot in the middle, how do I do this?

I somehow click away or do something. 
Now when I click, the next dot is not connected.
What am I doing wrong?
How do I connect?

Thanks.

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,

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.

In my experience, ctrl works as intersection, and ctrl+shift works as subtraction.
Is it only me having this feature?
