I'm trying to correct the perspective of a photo in GIMP, but I can't seem to get it to apply to the entire image. The transformation applies to a small area and leaves empty white space around it.
When I select the Perspective tool and click anywhere in the canvas, the grid appears, already scaled to just the subject:
I set up my transformation to line up the product label with the guides:
How can I get GIMP to transform the entire image, and not add that extra white space?
What I've tried so far:
- Extending the grid to cover the entire canvas - this results in stretching the subject
- Changing the Clipping setting - no effect
- Fit Canvas To Layers - no effect
- Removing the guides - no effect
