Automated GIMP Processing of Web Site Images

Take advantage of The GIMP to perform mundane but needed image processing for Web sites.

Not only are the width and height available, but the position in the original xcf file is stored as well. This makes it easy to build pixel offset-based Web sites using The GIMP to position various graphical elements and have the Web site offsets updated automatically. A Web site can be designed at 1600x1200 and saved in xcf files. The scaling script can then be used to generate an 800x600 version of the Web site automatically, together with the corresponding image offset and size metadata.


As I have little interactive skill with The GIMP, the cake multilayer images in Figures 1 and 2 were kindly created for the article by Dennis Braun (
