Image::Filter is a perl module that can apply image filters. This module implements a weighted average greyscale routine. It uses the gd lib from Thomas Boutell.

Image::Filter is based on the concepts tought to me by my math professor J. Van Hee. This module wouldn't be possible without the work of Thomas Boutell on his gd library. Inspiration, but no code, was taken from Lincoln D. Steins GD implementation of that same gd lib.
