Benchmark: HTMLImageElement vs HTMLCanvasElement vs ImageBitmap Forked

Script Preparation code:

var
natrualWidth = 0,
naturalHeight = 0,

eleImg = document.createElement("img"),
cvsImg = document.createElement("canvas"),
bmpImg = null,

canvasEleImg = document.createElement("canvas"),
canvasCvsImg = document.createElement("canvas"),
canvasBmpImg = document.createElement("canvas"),

ctxEleImg = canvasEleImg.getContext("2d"),
ctxCvsImg = canvasCvsImg.getContext("2d"),
ctxBmpImg = canvasBmpImg.getContext("2d"),

doneLoading = false;

canvasEleImg.width = canvasBmpImg.width = canvasCvsImg.width = 640;
canvasEleImg.height = canvasBmpImg.height = canvasCvsImg.height = 480;

eleImg.addEventListener("load", function()
{
	cvsImg.width = naturalWidth = eleImg.naturalWidth;
	cvsImg.height = naturalHeight = eleImg.naturalHeight;
	cvsImg.getContext("2d").drawImage(eleImg, 0, 0, natrualWidth, naturalHeight, 0, 0, natrualWidth, naturalHeight);

	Promise.all([
		createImageBitmap(img)
	]).then(function(images)
	{
		imageBitmap = images[0];

		doneLoading = true;
	}, false);
});
eleImg.src = "https://new.imagehostx.com/upload/2025/02/22/e5306382-3a31-4214-bbcf-b1661db689cb_1740191464.jpg";

Tests:

HTMLImageElement
if (doneLoading) ctxEleImg.drawImage(eleImg, 0, 0, natrualWidth, naturalHeight, 0, 0, natrualWidth, naturalHeight);
HTMLCanvasElement
if (doneLoading) ctxCvsImg.drawImage(cvsImg, 0, 0, natrualWidth, naturalHeight, 0, 0, natrualWidth, naturalHeight);
ImageBitmap
if (doneLoading) ctxBmpImg.drawImage(bmpImg, 0, 0, natrualWidth, naturalHeight, 0, 0, natrualWidth, naturalHeight);
