Zebra_Image 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). The code is heavily commented and generates no warnings/errors/notices when PHP’s error reporting level is set to E_ALL. It can rescale, flip, rotate, and crop images. It supports loading and saving images in the GIF, JPEG, and PNG formats and preserves transparency for GIF, PNG, and PNG24. It can re-size images to an exact given width and height and still maintain aspect ratio.
