ImageScript

zero-dependency JavaScript image manipulation

ImageScript is a zero-dependency alternative to common JavaScript bitmap image manipulation tools. It can achieve much more performant results by utilizing lower-level memory access, less memory copying and WebAssembly / native binaries for decoding and encoding.

Features

• Decoding images
  • PNGs (grayscale, RGB, indexed colors) with and without alpha channels
  • JPEGs (grayscale, RGB, CMYK)
  • TIFFs
• Decoding GIFs
• Rendering SVGs
• Rendering vector fonts
• Image manipulation functions (crop , rotate , composite, …)
• Color manipulation functions (invert , hueShift, …)
• Color information functions (averageColor , dominantColor, …)
• Encoding images as PNGs , JPEGs and GIFs

Example

import {Image} from "jsr:@matmen/imagescript";

const input = await Deno.readFile('./image.png');
const image = await Image.decode(input);
image.rotate(180);

const output = await image.encode();
await Deno.writeFile('./output.png', output);
