---

**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](https://imagescript.matmen.dev/Image.html#.decode)

  - PNGs (grayscale, RGB, indexed colors) with and without alpha channels

  - JPEGs (grayscale, RGB, CMYK)

  - TIFFs

- [Decoding GIFs](https://imagescript.matmen.dev/GIF.html#.decode)

- [Rendering SVGs](https://imagescript.matmen.dev/Image.html#.renderSVG)

- [Rendering vector fonts](https://imagescript.matmen.dev/Image.html#.renderText)

- Image manipulation functions ([crop](https://imagescript.matmen.dev/Image.html#crop)

  , [rotate](https://imagescript.matmen.dev/Image.html#rotate)

  , [composite](https://imagescript.matmen.dev/Image.html#composite), ...)

- Color manipulation functions ([invert](https://imagescript.matmen.dev/Image.html##invert)

  , [hueShift](https://imagescript.matmen.dev/Image.html##hueshift), ...)

- Color information functions ([averageColor](https://imagescript.matmen.dev/Image.html#averageColor)

  , [dominantColor](https://imagescript.matmen.dev/Image.html#dominantColor), ...)

- Encoding images as [PNGs](https://imagescript.matmen.dev/Image.html#encode)

  , [JPEGs](https://imagescript.matmen.dev/Image.html#encodejpeg)

  , [WEBPs](https://imagescript.matmen.dev/Image.html#encodeWEBP)

  and [GIFs](https://imagescript.matmen.dev/GIF.html#encode)
