| Transform an image into different aspect ratios |

Hello,
I just started today with this quest:
1.) Read the filename and save it.
2.) Resize the image to a specific aspect ratio.
3.) Add a prefix to the filename and save it as an jpeg in a specific folder.
4.) Undo all steps and repeat steps 2. und 3. different values.
I came this far:
Code:
from gimpfu import *
# The real code.
def setAspectRatios():
# create the object of the image
image=gimp.image_list()[0]
# resizes the file to AR 2-3
pdb.gimp_image_resize(image, 5333, 8000, -345, 0)
# create the new name AR 2-3
img_name_ar_2_3 = "AR_2-3_" + image.name
# define drawable
drw = image.layers[0]
# save the image as jpeg
pdb.file_jpeg_save(image, drw, img_name_ar_2_3, img_name_ar_2_3, 0.90, 0, 1, 1, "Aspect Ratio 2-3", 3, 1, 0, 2)
register(
'set-aspect-ratios', # Unique ID,
'create different aspect ratios', # Description/title
'Add a white layer', # Help
"Author", # KJ
"Author", # Copyright KJ
"2024", # Copyright 2024
'Set Aspect Ratios', # The menu label
"RGB*", # The type of images it can work on. Use "*" for all types
# [ # List of input parameters
# (PF_IMAGE, "image", "Input image", None)
#
#],
[], # List of output parameters
setAspectRatios, # The Python code that implementsthe plugin
menu="<Image>/Layer", # Where the menu label above appears
)
main()
But I have some questions to fill the blanks:
Q1: I know now that image.name does not work properly. Is there another way besides using pdb.gimp_image_get_filename(image) and trim the complete path down to the filename to just get the name of the file I imported?
Q2: What type is "drawable" - I could not find a good explanation. Do I use this correctly?
Q3: Undo is still a miracle for me. I saw that you can create groups and that you can enable, freeze, and disable it but I dont know how to trigger a simple undo to reverse steps 2. and 3. to the back to the original image.
Thanks in advance!

I lost the tool detail box. For instance, the Dodge/burn tool is active but I cannot see the size, opacity and so on sliders. How do I get it back?

Hello,
I have a strange question that I hope I can explain well. I have created 60 frames of a line image that shrinks from right to left. Here is a representation to try and show what I am doing
----->
--->
->
I did this by creating each image 7 pixels shorter and then displaying image 60 to 1 in a countdown
What I want to do now is reverse the animation like this
<------
<---
<-
The problem is that I am trying to do this in a program that is used to create graphics for PC Sensor Panels (Aida64)
Apparently it displays images left justified so the only way I can think to do this is to push the frames from right to left like this
<-----
..<---
....<-
and make the ... transparent
Is there an easier way?
Thanks

something strange. l am using linux lite 6. i was looking on the internet for something similar to the old windows paint program and i came across, you guessed it, gimp. so being a little smart, i looked in my menu under graphics and all accessories. no gimp. next smart thing. i typed gimp in terminal. gimp 2.10 loaded up on my screen, i did my old paint things successfully, with no error messages, and closed gimp. i incorrectly assumed i had installed gimp on my computer by type gimp in terminal. alas no gimp in my menu. so what the heck was that? and i can do it again.

Hi All,
I currently have version 3.2.6 installed in Gimp 2.10.36 in windows 11...
Do I install version 333 directly on top of the old version or does it need to be uninstalled?
How do I uninstall it?
Thanks,
FlutteringBy

| Trouble with a plugin |

Good evening,
I am using GIMP 2.10.18 on a MX Linux distro. I can't use nor see this plugin, despite being included into the /home/username/.config/GIMP/2.10/plug-ins/ folder:
https://www.gimpscripts.net/2020/12/cale...64bit.html
I know that it is a plugin which is apparently designed for the Windows version of GIMP. But, can I use it somehow on Linux? Can I convert to a format that Linux understands it?
I tried to launch GIMP for Windows via Wine and put that plugin in the corresponding plug-ins folder, but when I launch that plugin, GIMP hangs up.
Thanks in advance!

Hello,
I have a problem with script in Python-FU. I want to run the script by drag-and-drop two files on .bat file.
Script is working fine when I run it from GIMP menu, but from .bat i receive error:
Code:
Error: Invalid number of arguments for python-fu-file-import-as-layer (expected 5 but received 2)
.bat file:
Code:
@echo off
setlocal enabledelayedexpansion
if "%~2"=="" (
echo Please provide two file paths.
pause
exit /b
)
set "file1=%~1"
set "file2=%~2"
start "" "C:\Program Files\GIMP 2\bin\gimp-2.10.exe" -b "(python-fu-file-import-as-layer \"%file1%\" \"%file2%\")"
exit /b
file-import-as-layer.py
Code:
#!/usr/bin/env python2
from gimpfu import *
def file_import_as_layer(fname_one, fname_two, image, layer):
try:
# Load the main image
image = pdb.gimp_file_load(fname_one, fname_one)
# Check if the image loaded successfully
if not image:
raise Exception("Failed to load the main image.")
# Load the second image as a layer
drawable2 = pdb.gimp_file_load_layer(image, fname_two)
# Check if the layer loaded successfully
if not drawable2:
raise Exception("Failed to load the second image as a layer.")
# Make sure the second layer is visible
pdb.gimp_item_set_visible(drawable2, True)
# Get the layer position in the layer stack
position = len(image.layers)
# Create a new image for both layers
new_image = pdb.gimp_image_new(image.width, image.height, image.base_type)
# Duplicate the main layer
new_layer_main = pdb.gimp_layer_new_from_drawable(image.layers[0], new_image)
# Duplicate the second layer
new_layer_inserted = pdb.gimp_layer_new_from_drawable(drawable2, new_image)
# Insert the main layer into the new image
pdb.gimp_image_insert_layer(new_image, new_layer_main, None, 0)
# Insert the second layer into the new image
pdb.gimp_image_insert_layer(new_image, new_layer_inserted, None, 1)
# Show the new image with both layers
gimp.Display(new_image)
except Exception as e:
pdb.gimp_message("Error: {}".format(str(e)))
# Register the Python-fu script
register(
"python_fu_file_import_as_layer",
"Import a file as a layer",
"Import a file as a layer into the current image",
"Author",
"Author",
"2024",

"*",
[
(PF_STRING, "fname_one", "Main Image", ""),
(PF_STRING, "fname_two", "Image to import as layer", "")
],
[],

)
main()
What arguments I need to specify?
