I am working on an application to scale an image, but the bottom part of the image contains a special pattern that must be copied over and repeated since it is distorted during scaling. I have the following section of code:

I'm running GIMP 2.10.38, but I've also downloaded 3.04 as an appimage and had the same issue with it. I'm on the latest update of MX Linux.

A few months ago, whenever I try and use the clone tool, the tool size seemingly randomly changes size and orientation when I move the cursor or tool. I've tried disabling dynamics options, but this had no effect. In the paint dynamics editor, the opacity, size, and angle have an x in the random column, which I cannot change. While I don't know if that is related, it may be relevant.

I've uninstalled and reinstalled gimp to no avail. As I've said, I downloaded 3.04 as an appimage with the same results. 

Running this for graphics:

I have windows 11. I open Gimp 3.04 and try to open an image then gimp closes, I have uninstalled and removed everything and reinstalled but the same thing happens time and time again

I am currently preparing a new site, in which I intend to show how I created some of my images.
Let me give you an example (published in January on https://mjbarmish.fr). This image's primary quality is its delicacy and refined character.
However, it requires the use of at least 4 Gimp filters, not including sharpness, exposure, contrast, etc.

   

1. At the beginning there is a backlit photo of the church of a small village. It is of no interest.
   

2. I started by giving it some color with Normal map at a fairly high level 201.
   

3. Then to force the tones a little, I merged the original photo in subtraction mode.
   

4. Then I added some sharpening, before submitting the result to the recursive despeckle with extreme settings 30 -1 256.
   

5. At this point the picture becomes interesting; but it clearly lacks a finishing touch.
I then had the idea of sticking it on itself, but turning it over,
   

6. and merged in HSV saturation mode. As I expected, an aesthetically pleasing addition occurred. After, of course, exposure, sharpness, contrast...
   

Which just goes to show that you should never throw away a bad photo.

See you soon

In Gimp 2.x i was able to copy and paste sections of a pdf (imported as an image if that makes any difference) whereas in 3.x i cannot.

I have uninstalled and reinstalled both versions a number of times, finally reinstalling 2.8

Due to my inexperience i suspect "user error" rather than a bug.

Would anyone be so kind as to advise?

Thank you!

I have installed Gimp 3.04. When I try to save a file, Gimp closes automatically. I have uninstalled and deleted all files related to Gimp and reinstalled Gimp, but the same problem persists, windows 11

I am trying to get this image to centre on a custom sized piece of paper 210mm x 99mm (its for sublimation onto a coffee mug) 

I have an Epson printer and have changed all the settings to what I believe are the correct ones, - user defined paper size, fit to page, centre etc.

Currently I print the images on A4 sized paper and cut them down, this is wasteful and expensive !

The paper supplier says its not possible to print this using GIMP due to centering and scaling bugs, and has suggested I change photo manipulation software which I don't want to do as its taken me a year to fumble my way around Gimp ! 

Plus the fact it would cost me £67 for the new software just to do one job   

Thanks in advance from the UK

New user to Gimp.  So if there is something more I need to provide, let me know.

Gimp Version:  3.0.4
OS:  Windows 10
Attempting to use the Color/Hue Saturation feature to isolate one color in the picture but the colors are not translating correctly.

Original file was in RAW format
Was converted using RAW Therapee 5.11
Not sure if I selected the correct options, but the yellow changes to black when using the color/hue saturation option

See attached screenshot file

Thank you,

Margaret

For gimp 2.10, is my understanding correct?

Given a region's bytes from a layer ‘l’:

    r = l.get_pixel_rgn(0, 0, w, h)
    rb = r[:, :]

I think rb will hold the bytes of the channel's values in the machine's native endianess because:

- a region maps onto tiles,
- getting the tile's pixels uses a simple memcpy(), and
- a tile's pixels are in the native endianess.

I'm aware tile data in an XCF file is big-endian from
https://testing.developer.gimp.org/core/...ganization
But I'm interested in what's in memory and guaranteed to be seen through slicing a Python region into a string of bytes.

Hello! First time posting. Just started using GIMP again and downloaded the latest version, 3.0.4. It keeps crashing on me? All i'm doing is paning, zooming, and erasing, pretty simple stuff. This is the error I get, I have no idea how to interpret this:
