Hello here!
I've been trying to make a Python plugin for Gimp for two days now. For now, my goal is quite simple, I want to be able to create / duplicate layers, etc.
So I made my python file, put it in the right folder, registered it, etc.
Here is the code I got for now:
Code:
#!/usr/bin/env python
from gimpfu import *
def test_function(image, drawable):
pdb.gimp_drawable_set_name(drawable, "My new layer name")
pdb.gimp_message("Test 1")
width = drawable.width
pdb.gimp_message("Test 2")
height = drawable.height
pdb.gimp_message("Test 3")
img = gimp.image(width, height, RGB)
pdb.gimp_message("Test 4")
layer_one = gimp.layer(img, "My layer", width, height, RGB_IMAGE, 100, NORMAL_MODE)
pdb.gimp_message("Test 5")
img.add_layer(layer_one, 0)
pdb.gimp_message("Test 6")
register(
"python-fu-test-function",
"Test script",
"This is a test script",
"Me", "Me", "2022",
"Test",
"",
[
(PF_IMAGE, "image", "takes current image", None),
(PF_DRAWABLE, "drawable", "Input layer", None)
],
[],
test_function, menu="<Image>/File") # second item is menu location
main()
As a result, I got displayed in the warning console:
"Test 1"
"Test 2"
"Test 3"
And that's it. It seems that the line "img = gimp.image(width, height, RGB)" stops the script (without error message), while nothing seems particularly off with it.
Actually, this line of code was copy pasted from this documentation (sample, section 2.1).
As I'm working on this, I have the feeling to be dealing with a development that seems quite random. Not having the possibility to work in a proper development environment is really tiring, each time I'm coming up with something I have to save the python script, go in gimp, launch the script, see if it works, retry...
Do someone have advices on this matter?
Thank you very much.

I am sorry if this is something that I should be able to easily find on the net... but each and every tutorial / help page, gives basically the same answer... but it simply does not work.
How do I bind AND use then activate a keyboard (or mouse wheel) shortcut that allows me to rotate a custom brush so that I do not have to constantly go back and forth with a slider to make micro-adjustments?
Thank you for any assistance.

Hi,
I have a weird behavior on my Linux installation.
I have Gimp 2.10.30 and I'm not able to select a part of my image or to crop it.
Icons are available and I can click on them and set a fixed ratio, but when I try to set the fixed ratio or free ration clicking on the image, nothing happen.
I have the same behavior if I use my graphic tablet.
To be clear: mode is in "replace the current selection" not in "subtract"
What's going on ?
thx

| Remove background without pixelated edges |

Hey all,
I'm trying to cut a single piece out of a full jpg, delete the background, and change the color from black to white. When I select the image and delete everything else the edges come out looking all pixelated. I was using the square select to remove the big chunks, then I was using the magic wand to select the image I want to save and use the invert select option to remove the background.
The magic wand selects by color, but there is a range of grayscale around the boarder when I delete the bulk of the image.
Any help is appreciated.
Greg
