Author quicker way to crop out empty area?

After a small rotation (e.g. 1 degree) and/or lens distortion correction,
one usually wants to crop to exclude the empty/transparent area, so that the
photo is rectangular again.

To do this, I manually position a crop region just large enough that none of
the empty area is included. Usually, I first make a cropping rectangle
roughly the right size, then zoom in to fine adjust the edges. This is
pretty boring and tedious. Is there a more automatic way?

Hi peter,

Control click that layer.

Good luck,

Ron -
That doesn't seem to address the OP's problem. Could you elucidate?

Ctrl-click the layer in the palette to make a election, then Image>Crop.

Ctrl-click seems to be a short cut for loading the layer mask, i.e. select
everything non-transparent.

What I want is to select the largest fixed ratio (e.g. 4:3) rectangular
region that fits in the non-transparent area. I imagine if this feature
exits, it would be somewhat interactive so the user can specify the aspect
ratio, and be allow to move the region around.

set the crop tool to the specific proportion you need?
then only use the corners to resize it

Not totally, because it is assumed that such a crop would be subjective
in its selection. But here is the best way I have found:

Select the whole image with the crop tool by starting from outside the
bounds of the document and ending outside the bounds (with no special
keys held down). You can be as sloppy as you want, of course, because it
will basically select the whole image when you do this.

Then, from one of the corners, hold down the command-option (or
control-alt, if your are on Windows) keys while resizing the crop box.
This will resize all four corners at once, keeping the center point
constant. Just resize until you have no transparent areas within the
crop, hit enter, and you'll be done!

Go to the Adobe Exchange and search for a script named autocropv2.jsx.
This script was made to do exactly what you need. It works on CS and
CS2, not sure about other versions.

Bye for now.
