Spectrum

A JavaScript library for image manipulation.

Features

• Ability to read .png and .ppm (and similar) files.
• Ability to manipulate images by pixel.
• Asynchronous execution.
• Minimalistic CLI interface language.

Examples

const Image = require("spectrum").Image;
Image.fromFile("cat.png").invert().output("scary-cat.png");

This inverts each RGB value, then writes the result to scary-cat.png.
