Bug
I want to embed cmyk images in pdf using img.dataMode = Image.MODE_MIME. That should take the image and embed it into pdf without any painting or editing. But all cmyk images are black.
JPG

Files img.jpg.zip out.pdf

const canvas = createCanvas(200, 200, "pdf")
const ctx = canvas.getContext("2d")
