The purpose of this script is to convert animation strips or sheets back into collections of layers. These can be saved as an animated GIF image or used for any other purpose.
This script will create a new filter under Filters -> Animation -> Unstrip. The script will take number of rows and columns in animation sheet. For strip, simply keep number of rows as 1. Upon activation, this script will create a new image with rows * columns layers corresponding to each animation frame. The order of layers is such that when saved as animated GIF it will play left to right, then top to bottom.
