image processing library for PHP

• requires no installation, no other libraries, no ImageMagick, just PHP GD
• reads and writes TGA, BMP, PNM, PPM, PGM, PBM and all formats supported by PHP GD (jpg, gif, png...)
• lots of filters/effects: sepia, vibrance, contrast, posterize, emboss, sharpen, blur...
• can convert to grayscale and black&white using various dithering methods (Stucki, Sierra, Burkes, Floyd Steinberg...)
