feather selection doesn't work at edges of images
GIMP version:
git master as of June 2019; git 2.10.10
Operating System: Linux (I've also seen it reported on Windows)
Description of the bug
Feathering the selection doesn't have an effect at the edges of the canvas (or payer probably; i didn't test that).
I'm not sure it's a bug, but if not, Feather Selection should have a checkbox to match Shrink Selection, to control the behaviour.
Reproduction
Is the bug reproducible? [Always / Randomly / Happened only once ] yes
Reproduction steps:
- make an image e.g. 200x200px
- select all
- select->feather e.g. by 40 pixels
- fill with black, and note that the black goes all the way to the edges.
Now,
- select all
- shrink selection by 1px (make sure "Selected areas continue outside the image" is unchecked or it silently refuse to do anything)
- select->feather again by 40px
- fill with black, and note the black now fades to grey at the edges of the image.
Often this is eactly what you want, but sometimes it isn't, in which case you have to grow the image (or layer) by 1px and then shrink it afterwards.
I'm not actually sure which behaviour was intended - maybe this is a feature request.
