Resize canvas around arbitrary anchor?

Hi,

When resizing a canvas, you can choose an anchor in the center, or any of the four sides or corners. But is there a way to specify an arbitrary location as the anchor? For example, I'd like to click on a point in an image and have the canvas resized so it's 800 pixels above that point, 200 pixels below, and 400 on the left and right.

(The reason is that I have a bunch of poorly scanned pages of a book. I need to deskew them, clean them up, and then crop them. The page number is in the same location on every page - center bottom - so I want to base the crop off the location of the page number.)

Thank you,

Bob

Well apparently there's no built-in solution. So I wrote a script. I open the image of the page, manually put a selection box around the page number, then run the script. The script gets the coordinates of the selection and resizes the canvas so there's an 8.5x11 page with the page number positioned 3/4" from the bottom and in the horizontal center.

You are looking for automation, right? Automation is probably doable if the number is consistent and always at the same relative position. That can be starting point to record action which will create vector rectangle/square path at some certain position then resize it using some specific anchor point, perhaps it will need to change path multiple times and lastly to convert path to selection followed by Image > Crop or to use the Crop tool. One more time: this is doable only if pages and numbers shares exact same dimensions and position.
