Open Source PHP API to Manipulate Images

PHP Library that enables Software programmers to resize, sharp, merge, colorize, fill and rotate images.

The Gregwar's Image is an open source object-oriented library that gives software developers the capability to manipulate images inside their own PHP applications. Using the API, you can resize, scale resize, force resize, crop resize, zoom crop, crop and negate images. Furthermore, the API also allows you to set brightness, contrast, convert the image to greyscale, emboss the image, smooth the image, sharpen image, colorize the image, and more.

The API never applies a feature on an opened image. Instead - The API first caches all the images and then applies the features. The API adds the image in the operations array consisting of name, type and you can use the hash to look up for the file in the cache.
