I am trying to develop my first python script and i am stumbling into some questions,
i am quite stuck ....
and i am wondering whether i am searching for something which is not possible:


a) As a starting point i was trying to recreate the  Brightness-Contrast menu using the: pdb.gimp_drawable_brightness_contrast() function.

I managed to setup the UI for brightness and contrast, but:
I would like to be able to recreate the functionality of the original menu,
especially including the realtime update in my image,
which the original gimp menu is capable off, but how? is it even possible?

b) I would like to be able to create several python scripts which are able to call each other,
but i could not find a error-free way to call another python script.
For example: the first file  "contrast_filter.py" which calls after execution the second file   "levels_filter.py"


Any suggestions would be very appreciated - Thanks

I'm using a Mac (OSX Big Sur) and when using either McGimp or Gimp, my cursor is nearly always misaligned with what actually happens on screen - I have to aim the cursor above wherever I'd like to do something. I'm using the Mac's trackpad.

There's also a lag when doing certain things, such as cutting an area after selecting it. I have to save and reopen the file to see the area cut out.

Any ideas? Is it down to it being Big Sur?

How do you make shiny, metallic text like in the image below?

Can we make something like this in GIMP ? I am not sure I am skilled enough to portray the reflections and other effects on the glass

   

Good Day

I need help with the following I want to learn how to take the middel part out of this screen, and save it on it own
The gold part.

Can any one tell me if the 2.10.22 version of Gimp supports any HDR editing or bracketing? I dont want to pay for something like Aurora HDR if there is a free way to do this? I am wanting to work on 360 photos to use them in virtual tours so a stitching option would also be very useful.

Hello,

Thanks in advance for your wise help!

- Example : I have opened an image of 1000 x 500
- With the selection tool, I select a part of that image. For example, I select 200 x 300 of that image
- I want this selection of 200 x 300 to be a new jpeg file
- So I create a new image BUT THE SIZE OF MY SELECTION (200 x 300) IS NOT KEPT IN MEMORY!
That new image has automatically the size of the main image : 1000 x 500
BUT I WANT A NEW IMAGE WHICH WOULD AUTOMATICALLY BE 200 x 300, the size of my selection.

So instead, I have to memorize myself the size of my selection in my little head.
When I open a new image, I have to type in myself the size 200 x 300 which I have memorized.
It's okay when it's 200 x 300, but it's kind of challenging when it's 1426 x 1428, a good memory training!

I remember that in Photoshop, it did that : it memorized the size of my selection in a new image.

How can I do that with Gimp?
Or maybe is there another way around that issue ?

Thanks for your help

Hi.

I'm on Gimp 2.10.22 on MacOS Big Sur (latest). No matter what I try, "Alpha to selection" does not work.
I'm doing the following:
1. create new workspace with white bg
2. I use a text tool to add a text to canvas: "TEST"
3. I right click on a later and select "Alpha to Selection"
I expect for actual text letters to be selected, but that does not happen, in fact nothing happens.
I tried reinstalling from zero, does not help.

Am I doing something wrong, or is this a bug on Mac OS?

Help please.

After reading many posts that suggest that it's not possible (or even desirable) to browse and open images by thumbnail from within GIMP, I put together this method which allows me to work in the same way that I did in PaintShop Pro (before it became to slow and messy to use).

The way I like to work is that from within PaintShop, I type <Ctrl-B> to bring up a thumbnail browser, browse to a folder, then double-click on a thumbnail to edit that image.  I also like the browser to remember the same folder next time I type <Ctrl-B>.

What I've done to achieve this is:

1. Install an external app that allows thumbnail browsing.  I've found that "Unifie" does exactly what I need as it is focused more on the thumbnail browsing rather than actual editing.
2. In Unifie, open the Tools>>Options dialog and add GIMP as an external program.  In my case "C:\Program Files\GIMP 2\bin\gimp-2.10.exe".
3. In the Unifie Tools>>Mouse/Keyboard dialog, change the "Popup Window" - "Click" entry to GIMP (External Tool N).
4. Now, download and install "AutoHotKey". This is an app for creating keyboard shortcuts.
5. Create a file called something like "AutoHotKeys.ahk".  I keep mine in "My Documents". Put the following text in it:

    #IfWinActive ahk_exe gimp-2.10.exe
    ^b::
    Run, "c:\Program Files\Unifie\unifie.exe"
    return

6. Type Win+R and enter "shelltartup".
7. In the folder: "C:\Users\XXXXXX\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup", create a shortcut to your AutoHotKeys.ahk file.
8. Log out and back in.

The AutoHotKeys script should now run when you login.  The script tells windows to run Unifie when you type <Ctrl-B> from within GIMP.

I hope others find this a useful addition to what I'm finding to be a very useful free program.

At least in my Xubuntu 18.04 installation, it's not there anymore (2.10.22 on Win 10 looks normal). I upgraded from 2.10.14 to 2.1.22 yesterday via PPA http://ppa.launchpad.net/ubuntuhandbook1/gimp/ubuntu and it doesn't appear to have any support for Python plugins. The entire Python-Fu entry is missing from the Filters menu and other python actions are gone (e.g., Filters | Web | Slice). I had installed Resynthesizer and the scripts are still there in my profile directory but they're not visible in Gimp either.

I found more than a few similar occurrences online (not limited to 2.10.22) and some referenced installing gimp-python but apt says it doesn't exist. No solution yet - Any idea what's missing?

Thanks!
