Apparently GIMP 3.0.0 had an issue with the initial installation file where the python console was missing and python plugins were affected and not showing in the menus. GIMP 3.0.1 was released and fixed this problem. GIMP 3.02 with additional bug fixes was released and now python plugins no longer are showing in the menu. I reinstalled GIMP 3.0.1 and the plugins are back in the menus.
I'm trying to port a Gimp 2 script to Gimp 3 and got most of it figured out by trying stuff out in the python console.
Code:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import time
from gimpfu import *
def sprites2layers(image, layer, sample, minimal_dimensions):
'''
"Separates objects on one layer to their own layer. Handy for Spritesheets"
Parameters:
image -- The current image.
layer -- The layer of the image that is selected.
sample -- sample every nth pixel of layer tile
minimal_dimensions -- minimal dimension of object to be placed in "objects" layer group
'''

I've hit a snag with lines 65 and 129 with "Tile = layer_offscreen.get_tile(False, tile_row, tile_col)".
in Gimp 3 "drawable.get_tile()" doesn't exist, what is the alternative to this?
Hi guys,
Problem: upright picture (portrait) of a door. Exif in original jpg is right,top.
I send it to gimp. The door now is shown in landscape, the exif now is changed to top,left.
I'm not sure, but maybe once there was a popup how to threat orientation of origin.
But now this popup is gone and I cannot find the option to change this behaviour.
Any help?
I tried on Reddit yesterday but no-one replied, I hope someone can help here.
When I installed Gimp 3.0.1 along side my existing Gimp 2 installation on Windows 10, the Gimp 3 installer picked up all*rc files from my Gimp 2 installation, however when I deleted the menurc file from Gimp 3's path (a.k.a "C:\Users\...\Appdata\Roaming\Gimp\3.0") not only the keyboard shortcuts were not reset, but also the menurc file was not recreated in the above path (as it does in Gimp 2). I even tried copying another menurc file of mine, with different keyboard shortcuts, but Gimp 3 fails to read it.
In short, i'm stuck with the custom keyboard shortcuts I had in Gimp 2, and I cannot reset them in Gimp 3. Also, I'm not able to use any menurc file (I have a couple of them with different sets of custom keyboard shortcuts).
Is there any kind of cache file I need to delete or something? Is there any other path I need to look at, where Gimp 3 picks up the old menurc file from? How come it does not recreate the menurc file when I delete it?
Btw, the controllerrc file works fine (it gets recreated when I delete it, I can copy there other versions of it and Gimp 3 loads it, etc). Is there a bug specifically for the menurc file in Gimp 3?
I download resynthesizer 3.0 and put the script files in the GIMP 3.0 script folder and the exe file in the GIMP plugin folder. I am using GIMP 3.0.0-1 and find Resynthesizer in the menu, so GIMP finds it. When I try to use Resynthesizer, I get the menu, but when I activate the plugin, I get an error, and the plugin stops. Is the plugin ready for GIMP 3.0.0-1?
In GIMP 3.0.0 (Mac OS 13.7.4 Ventura) clicking on a color in the "Change Foreground Color" dialog immediately causes the dialog window to disappear. The color is changed, yes, but it seems you have to do it incrementally, step by step, rather than making all the guesstimate changes and then clicking "Okay" as it was in 2.10. I hope that this is a bug rather than a feature. I hope even more that I've simply overlooked a setting somewhere.
The option to inset symbol or emoji under the Edit menu is gone. It's a relatively minor thing, perhaps, but I wish I still had it. Why take options away with the new version (3.0.0, in my case)?
Hi
I was hoping someone could help me.
I am trying to import a Warhammer 40k kill team data card download as an pdf and simply print it out on size A6 paper.
I would also like to create a template for future data cards.
I have tried simply changing the printer properties in gimp and the printer to match but I keep getting a paper size error (E1) on my HP printer.
I am new to Gimp.
Background: the shellout.py (7 years old script) is an approach for calling NikCollection Filters and using the result in GIMP. It still worked with win10 & win11 until GIMP 3.x.
I’m having trouble converting the Python plug-in script from GIMP 2.x to 3.x.
Thank @Ofnuts for pointing out the helloworld plugin example, that helped me understand the basics a little bit.
I've been fighting this for days now and I need help. What I thinki should be a simple process is absolutely baffeling. I have a number of color .jpeg images and no matter what method I use, fuzzy select (sort of worked but too much edge pixels}, color select, path select, I can't get it to work. Out of desparation I upgraded from ver 2.1 to 3.0 and still no result. I finally resorted to picking a no-brainer eazy peazy image, shades of grey, simple shape and still can't get it to work.
Although it's going to take a lot more time I think I've decided to do the path select method. The problem is that when the path is complete and, following all the directions from tutorials and posted online, I right click and select Select/Selection from paths then delete nothing happens. I've closed the view and started over several times and zilch. I'll attach a copy of the image (mug clip2.jpeg). Somewhere along the way either I'm missing something or maybe there's a glitch in my Gimp. I appreciate any help.
