What is this?
Jimp is an image processing library written entirely in JavaScript for Node.js, with zero external or native dependencies.
Is it a standalone app or a library I add to my code?
It's a library you install via a package manager and import into your Node.js project; it's modular, with custom plugins and file-type encoders/decoders you can add or remove.
How do I add it to a project?
Install the package and require/import Jimp in your Node.js code, then use its API to load, manipulate and save images.
Do I need native libraries like GraphicsMagick or ImageMagick first?
No, Jimp has zero external or native dependencies since it's written entirely in pure JavaScript.
Does it need a specific Node version?
The project requires Node.js version 18 or newer according to the engines field.
Who would use this?
Node.js developers who need to process or manipulate images (resize, crop, blur, composite, etc.) without installing native image libraries.
Does it work without a server or internet connection?
Since it's a pure JS library with no external services, all processing happens locally in the Node process.

Can I extend Jimp with custom plugins?
Yes, Jimp supports custom plugins and lets you add or remove file-type encoders/decoders and image manipulation methods via @jimp/custom.
