So you've just rotated your image and now have four nice transparent triangles in the corners. So what do you do? Here's a way of handling it:

  • Select/Alpha Range/Select Fully Transparent
  • Select/Grow/Shrink... (Radius 1px)
  • Edit/Inpaint

This should select the corners and give AP the opportunity to apply its Inpainting algorithm. At best it's a perfect fix. At worst, it's a start and you can clone bits that are not inpainted so well.

 

You do need to do the Grow, by the way, as without it you can get missed pixels and an inpaint that is not fully opaque (I think these are bugs and have reported them - until the fix, you need the Grow).

Dave, good tip, thanks! That is a common issue.

I've just found that you have to rasterise before inpainting into transparent corners (and after canvas stretch).

Process:

  • Layer/Rasterise…

  • Select/Alpha Range/Select Opaque

  • Select/Invert Pixel Selection

  • Edit/Inpaint

  • Select/Deselect

Macro to do this in one click attached.

Having ' straightened '  and cropped a photo , I cannot get the ' shrink/grow ' facility to work ! 

I've followed the instructions both on the ' Straightening ' video tutorial and 'dmstrakers ' method.

The option to shrink / grow remains greyed out !

Here is how I learned to do this.  Made a very amateurish "How to," for myself.  Hope it will help.

Thanks jmwellborn , think I've sorted it. 

Straightened a photo and cropped it BUT seem to have left a little of the photo framing border on ! 

I could only select ' alpha range - opaque '  !! 

Removed the offending border edges and all sides fine ( for now ! )
