Today I once again found myself needing to stitch screenshots together. It has been a while since I last had to do this (back then, I used some random app). Because I started using GIMP for more and more tasks, I wanted to do this in GIMP as well now.
Luckily, I found this Reddit post. I will repeat the steps here, both as a mental aid and in case that the original posts disappears. Also, I have slightly adjusted the steps.
- Open GIMP
File > Openthe top most screenshot
File > Open as Layers...all other screenshots
- ∀ layers: set opacity to ~50%. (Select layer in the layer list on the left, then click opacity bar above.)
Image > Canvas Size...: liberally increase the canvas height
Mto select the Move tool
- ∀ layers: select the layer and use the arrow keys to move them up/down. Use Shift+⇅ for rough moving. Zoom in on the canvas to get the alignment pixel-perfect. Increase the canvas height again if necessary.
- ∀ layers: set the opacity back to 100%
Image > Fit Canvas to Layers
File > Export As...
