The pure PHP graphics library

gfx-php - The pure PHP graphics library

, _(*1)

This library implements input, output and processing of raster images in pure PHP, so that image processing extensions (Gd, Imagick) are not required., _(*2)

This allows developers to eliminate some portability issues from their applications., _(*3)

Features

• Format support includes PNG, GIF, BMP and the Netpbm formats (See docs: File formats).
• Support for scaling, cropping, format conversion and colorspace transformations (See docs: Image operations).
• Pure PHP: This library does not require Gd, ImageMagick or GraphicsMagick extensions.

Quick start

Requirements

• PHP 7.0 or newer.
• zlib extension, for reading PNG files.

Installation

composer install mike42/gfx-php

Basic usage

<?php

• See the examples/ sub-folder for snippets.

Contributing

This project is open to all kinds of contributions, including suggestions, documentation fixes, examples, formats and image processing algorithms., _(*6)

Some ideas for improvement listed in the issue tracker. Code contributions must be releasable under the LGPLv3 or later., _(*7)

Scope

As a small project, we can't do everything. In particular, gfx-php is not likely to ever perform non-raster operations:, _(*8)

• vector image formats (PDF, SVG, EPS, etc).
• anything involving vector fonts
