Export iOS App Icons and Images from an Image

This Script-Fu script automatically generates all the required and recommend app icons with the proper names and resolutions for the various iOS devices from a single source image.

For each app icon: the source image* is duplicated, then the duplicated image is scaled, then the scaled duplicate image is exported to a .png file, and finally the scaled duplicate image is deleted. The resulting .png files have the proper names and resolutions for iOS app icons for iPad and iPhone/iPod touch for both normal and retina displays.

*The recommended resolution of the source image is 1024 x 1024
