Zebra_Image, a lightweight image manipulation library written in PHP.

This is a compact (one-file only), lightweight, object-oriented image manipulation library written in and for PHP, that provides methods for performing several types of image manipulation operations. It doesn’t require any external libraries other than the GD2 extension (with which PHP usually comes pre-compiled with).

With this library you can resize, flip, rotate , crop and sharpen images. All sort of filters can also be applied to images: negate, grayscale, brightness, contrast, colorize, edgedetect, emboss, gaussian blur, selective blur, mean removal, smooth and pixelate; multiple filters can be applied at once for creating custom filters; It supports loading and saving images in the GIF, JPEG and PNG formats and preserves transparency of GIF, PNG8 and PNG24 images.
