Resize and Match DPI

Resize-match-dpi is a GIMP Script-Fu script to resize or scale an image along with scaling the DPI. If we scan a 4.75″ x 4.70″ image at 300 DPI with a pixel resolution of 1425 x 1409 and we want to scale it down to 1280×1266, most programs will rescale the image but not touch the DPI. This means when the image is viewed or printed it will appear too small (4.27″ x 4.22″). This script scales the DPI to match the new pixel resolution so it will still appear as 4.75″ x 4.70″. Comments are greatly appreciated.
