Benchmark: drawImage() img vs canvas vs bitmap + cropping

Script Preparation code:

var canvas = document.createElement('canvas')
var context = canvas.getContext('2d')
var bitmap
var img = new Image()
img.onload = async () => {
    canvas.width = img.width
    canvas.height = img.height
    context.drawImage(img, 0, 0)
    bitmap = await createImageBitmap(img)
}
img.src = 'https://neurostof.nl/ns/letters.jpg'

var c = document.createElement('canvas').getContext('2d')


// bitmap && c.drawImage(img,    250, 250, 250, 250, 0, 0, 1000, 1000)
// bitmap && c.drawImage(canvas, 250, 250, 250, 250, 0, 0, 1000, 1000)
// bitmap && c.drawImage(bitmap, 250, 250, 250, 250, 0, 0, 1000, 1000)

Tests:

img
bitmap && c.drawImage(img, 250, 250, 250, 250, 0, 0, 1000, 1000)
canvas
bitmap && c.drawImage(canvas, 250, 250, 250, 250, 0, 0, 1000, 1000)
bitmap
bitmap && c.drawImage(bitmap, 250, 250, 250, 250, 0, 0, 1000, 1000)
