How to stretch only the edge of a pic

I'm working on a CD project with several panels. Since this is bulk produced they can't be exact as to where they cut the final panel image. Look at the PNG image I uploaded.

They're a safety area line where anything inside that is for sure going to be printed, then there is a trim line where they try to get as close as they can to when they cut the paper and then there's the bleed line which that area is in use if they miss the trim cut.

If I line my pic up to the edge of the bleed line, it may cut off parts of the pic that I really want. So what I want to do is to stretch only th every edge of my pic so it goes all the way to the bleed line, but I don't want it to distort the rest of the pic only the small border area around the whole pic. Any suggestions.

Still working on that CD?

A few ways for that image, only two edges needed.

Give the image transparency, Layer -> Transparency -> Add alpha channel.

Resize the canvas, quarter inch needed? (I added an 1/8" but should be 1/4") and drag the image to the top - right corner, gives a transparent edge left and bottom.

and a screenshot: https://i.imgur.com/ozKWhDZ.jpg

Then you could get away with just filling the transparency with a dark colour, ie. lock the pixels and then fill.

A better way might be with the resynthesizer + heal transparency plugin. You have that plugin ?

And with the original over the top the new edge looks like this: https://i.imgur.com/Ndlz6eY.jpg
