Ok, what’s the name of the function that grows the boundaries?

Are you also growing the layer boundaries? If you grow the canvas, but not the layer boundaries, you won't be able to draw on the new canvas area.

I need to enlarge the area of an image using one of the available GIMP's procedures. So, instead of using the GIMP's graphical interface and this tool http://docs.gimp.org/en/gimp-image-resize.html, I want to be able to have the same effects on a C code.

The function that should be called is this one, right? http://oldhome.schmorp.de/marc/pdb/gimp_image_resize.html

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
