resize canvas to selection

[_Mark_J_Peterson_]

Hi folks,
is there a way to resize the canvas to the current selection (similar to image>>crop which crops the image to the selection) ?
thanks!

good, than we are on the same page :)

>However, to be clear, I still stand by my comment that "canvas resize" from the image... canvas size menu does nothing but crop/delete. Please correct me if I'm wrong.

huh? no, AFAIK "image>>canvas size" does not delete any pixels. It is not true that it "does nothing but crop/delete". If you just acknowledged that resizing the canvas does not delete pixels outside the selection, BUT that "image>>canvas size" DOES DELETE, then how else do you change the canvas size?? I don't know any other method.

yes, see post #6

I stand corrected. Still doing tests on a background layer only. You are correct, Mark, that Image... canvas size (if applied to a layered doc) does allow to "reveal all" back the pixels you "cropped".

OK, J Maloney. If you can, I would be thankful if you could still reply to my other question: which OTHER method of canvas resizing did you use than "image>>canvas size" ?? (or did you mean the hide-crop method?)

As the thread evolved mainly around other issues, what's the bottom line for my original question now?

b Is there a way to: "resize canvas to selection" ?

(other than the workaround with a dummy layer)

1) Crop tool
2) Canvas size dialog
3) Selection, then image... crop

Thanks J.
Okay 1+2 is what I mentioned. And 3) does not resize the canvas, it delete-crops the image.

Turns out it was all down to terminological inexactitude.

The dummy-layer workaround does not work if any 1 of the 4 canvas borders is outside the current canvas.

What does that mean?

[_boarder_s_paradise_]

OK, admittedly my sentence didn't make any sense. What I wanted to say:

The dummy-layer workaround does not work if any 1 of the 4 borders of the selection (or the dummy-layer for that matter) is outside the current canvas.

It does for me! I made a layer, moved it so that half of the layer was outside the visible canvas area, then used the crop tool. I was able to snap to all the sides of the layer, including the edges that fell outside of the visible range. (it snapped to a point outside in the grey part of the work area.) Executing the crop changed the canvas dimensions to correspond to the edges of the layer.

Strange. I carefully tried it before posting, but it now works for me, too.
Thanks for your tip.

Select the layer then click Image > Trim > Transparent Pixels.
