Issues with pasting and aligning - accessd - 04-04-2025

Hi all,

I'm having trouble performing some basic tasks in Gimp 3. I'm not sure if they're bugs (in which case I will submit a report), or if the functionality has changed and I'm using it the wrong way. I commonly need to splice  images of two or more people together. The general process is as follows:

  1. use the selection tool to select part of  image A;
  2. click Crop to Selection; 
  3. resize the image to match the width or height of the new image I'm creating; 
  4. use the Crop tool to crop a fixed size;
  5. copy the resulting image and paste it into a new file;
  6. use Align and Distribute tool to move it to one side of the new image;
  7. repeat process with image B.
Since I upgraded to Gimp 3, when I copy the cropped image and paste it into a new file, I get all the information from before I used the Crop tool (Step 4). To get around this, I have to use the Copy Visible command, but shouldn't the Crop tool get rid of the rest of the image like the Crop to Selection command does?

Then, when I try to align the pasted layer in the new image, regardless of whether I try to align the layer vertically or horizontally, the Align and Distribute tool aligns the middle of the layer with the edge of the image, so half the layer is always out of view. Is this a bug or am I missing something?

I'm running Gimp 3.0.2 on Ubuntu 24.10.

Not a bug. Some things have changed with the align tool.

For the crop: In the Crop tool options there is a "Delete cropped pixels" option. Enable that, otherwise the undeleted pixels get carried over with a paste. This is the same as Gimp 2.10. You possibly had it enabled there but not in Gimp 3.0 You can use View -> View All toggle to see what is actually there.

The align tool: In the tool options there is a layout which determines alignment - center / edge... You might have to increase the width of the tool options dock to see it Wink
