Jimp

JavaScript Image Manipulation Program

An image processing library for Node written entirely in JavaScript, with zero native dependencies.

Notice of potentially breaking change

As of v0.10.4, core-js is no longer included with jimp or its extensions. If you rely on core-js, install it with either yarn add core-js or npm i core-js

Read before installing

Please be aware that Jimp is built on JavaScript implementations of image formats so in some cases that might allocate a lot of memory before using.

Installation

Installation: npm install --save jimp

API documentation can be found in the main jimp package
