An image processing library for PHP

Unique Features

These are the features that make Grafika unique from other libs:

Smart Crop - Grafika can guess the crop position based on the image content where the most important regions are preserved.
Animated GIF Support - It can resize animated GIFs on both GD and Imagick. On GD, Grafika uses its own GIF parser to do this.
5 Resize Modes - Resize is a first class citizen in Grafika. Call them directly using resizeFit, resizeFill, resizeExact, resizeExactWidth, and resizeExactHeight or use the generic resize api.
Image Compare - Find how similar two images are using perceptual hashes or check if they are exactly equal.
Advance Filters - Sobel and Floyd-Steinberg Dithering. More will be added in future releases.
Image Blending - Blend 2 images using the following modes: normal, multiply, overlay and screen.
Normalized API - No need to worry about the differences between GD and Imagick API, Grafika normalizes these operations for you.
