How Do I Edit a PDF in GIMP?

Since PDFs are image files, you can open and edit them in image-editing software such as GIMP. The type of editing you can do in GIMP is limited to using the GIMP tools you would use for any image, such as painting the background, adding text, cropping, erasing or blurring edges. You cannot access the text that is already in the PDF directly and change such things as font face or color.
