I need to enlarge the area of an image using one of the available GIMP’s procedures. So, instead of using the

The function that should be called is this one, right?

But it works when I need to shrink the canvas: on a 640x480 image, if I input smaller values the canvas is 
actually cut. Instead, if I want to add a 20px transparent border along the area (so I type 680 and 520 px, 
also with consistent offset values), the function just returns the original image.

How does it work? Thanks

Don't know about C, but that function works as advertised in a Python script, with a smaller or larger canvas.
