Simple Image Editor (SImEdi) creates and edits images with PHP using several plugins. The main class can load and save images in the GIF, PNG, or JPEG formats. It can also load plugin classes which provide additional image manipulation functionality. The plugin classes can perform image operations like flipping, resizing, adding text, and applying filters like sharpen, emboss, negate, gray_scale, brightness, contrast, colorize, edge detection, sketch, and sepia.
