This is a TypeScript implementation of the .qoi image format. The module provides two TransformStream classes to encode and decode ReadableStream<Uint8Array> in the desired format. The raw pixel format pipped into the encoder is expected to be a repeating sequence of [ r, g, b, a ]. This is also the format that is pipped out of the decoder. This implementation is based off the QOI Specification. You can find about more about QOI at their website: https://qoiformat.org/.

Example 1

 
import { QOIEncoderStream } from "@img/qoi";

await ReadableStream
  .from(async function* () {
    for (let r = 0; r < 256; ++r) {
      for (let c = 0; c < 256; ++c) {
        yield Uint8Array.from([255 - r, c, r, 255]);
      }
    }
  }())
  .pipeThrough(
    new QOIEncoderStream({
      width: 256,
      height: 256,
      channels: "rgb",
      colorspace: 0,
    }),
  )
  .pipeTo((await Deno.create("image.qoi")).writable);
