Don’t know if I’m doing something wrong here but …Back in old Gimp I’d be able to create a guide and surround an image. I am now unable to create a guide that sticks to the last bottom pixel (500), nor the rightmost pixel (200). As in an 200px by 500px image with a guide at pixel 500.
Also I found a selection box will not snap to guides when expanding it diagonally. Correction: it works and snaps diagonally but not if I have a fixed aspect ratio. With fixed aspect ratio only up/down left/right expansion of the selection box will snap to grid.
Update:
Found a way to have a guide at the bottom or the right hand side of the image: You use the Alignment tool. Does however not work by hand.
You are right about that. I could not make guides at the right and bottom edges; also anywhere outside of the image. The workaround I can think of is expand the canvas in every direction and then shrink it back to size once you are done.
A little off-topic but I am curious: is it possible to make diagonal guide lines?
@afre I am not sure but I do not think diagonal ones are possible, they weren’t in the past. Would be nice if there was a guides form where one could mention where the guide is in terms of some anchor or something
I don’t think anchors outside the image were possible in previous versions either
It is not possible to make Gimp guides other than horizontal / vertical to the canvas. With Gimp 2.10, the canvas can rotate. Unfortunately the guides also rotate. One way to see a horizontal line, is a screen ruler. screenshot: https://i.imgur.com/y6ssM9M.jpg
Placing guides relative to another.
The Measure tool, which shows distance and angle in Gimp 2.10 will add a guide at the end. In linux the keyboard “Window” (meta key??) + ctrl or alt works for me. screenshot: https://i.imgur.com/e1Bc54H.jpg
