Transparent padding to certain size
Hi there,
I'm EXTREMELY new to GIMP, I wanted to know if there's a way to, starting with an image having it padded with transparent color up to a given dimension. Ideally the padding should be all around and not just in one direction (i.e. the original image should be as centered as possible)

Thank you very much!

I'm no expert, but I know you can make the canvas size larger, in Image > Canvas Size.

I'm just discovering this as I'm looking it up now, but I see that in the Canvas Size dialog box, there's a section called Offset, which seems to control the positioning of the existing image relative to the new canvas area. If you increase the width and height of the canvas size and then click "Center" in the Offset section, it appears to do what you want.

If you're having trouble with transparency, go to the Layers window (Windows > Dockable Dialogs > Layers), right-click on the layer, then select "Add Alpha Channel" from the drop-down.
