Benchmark: FIXED! GetImageData with PutImageData vs just DrawImage

HTML Preparation code:

master
<canvas id='master' width='100' height='100'></canvas>
<canvas id='pid' width='100' height='100'></canvas>pid1
<canvas id='di' width='100' height='100'></canvas>di1
<canvas id='pid2' width='100' height='100'></canvas>pid2
<canvas id='di2' width='100' height='100'></canvas>di2

Script Preparation code:

var master = document.getElementById('master');
var masterctx = master.getContext('2d');
var pid = document.getElementById('pid').getContext('2d');
var di = document.getElementById('di').getContext('2d');
var pid2 = document.getElementById('pid2').getContext('2d');
var di2 = document.getElementById('di2').getContext('2d');

masterctx.fillRect(0,0,50,50);
masterctx.fillStyle = "red";
masterctx.fillRect(50,50,100,100);

Tests:

DrawImage whole master into di canvas
di.drawImage(master,0,0);
PutImageData whole master into pid canvas
let imgData = masterctx.getImageData(0,0,100,100); pid.putImageData(imgData,0,0);
DrawImage half master into di2 canvas
di2.drawImage(master,25,0,50,100,25,0,50,100);
PutImageData half master into pid2 canvas
let imgDatas = masterctx.getImageData(25,0,50,100); pid2.putImageData(imgDatas,25,0);
