createImageBitmap from blob [v.2.0.0-rc10]

[mcioffi]

Version: Deno 2.0.0-rc10

The Web Canvas API in Deno for createImageBitmap supports blobs. Added earlier this year in #21898

Observations

Currently seeing failures against standard jpg/pngs. The same code in a non-Deno environment, e.g. browser, works. Omission of jpg seems intentional from the deno library , but is worth bringing up as its widely supported in web apis

async function loadImage(url) {
  try{
    const response = await fetch(url);
    const blob = await response.blob();
    const imageBitmap = await createImageBitmap(blob);
    return imageBitmap;
  }
  catch (error) {
    console.log(error)
  }
}

const jpg = await loadImage("https://deno.com/images/artwork/deno_city.jpeg")

InvalidStateError: Unsupported type 'image/jpeg'
    at ext:deno_canvas/01_image.js:236:15
    at eventLoopTick (ext:core/01_core.js:175:7)

const png = await loadImage("https://deno.com/images/artwork/deno_news.png")

TypeError: Color type 'Rgb8' not supported
