Place an image element on top of a canvas

Question

I would like to place the picture of the hand on my black canvas next to the face. Is this possible to do? Is there a way to determine the position of the picture?

Here's my code:

 <script type="text/javascript" src="hand.jpg"></script> <img src="hand.jpg" id="y" /> <canvas id="myCanvas" width="1600" height="1200"></canvas> <script> var canvas; var canvasContext; window.onload = function() { canvas = document.getElementById('myCanvas'); canvasContext = canvas.getContext('2d'); canvasContext.fillStyle = 'black'; canvasContext.fillRect(0, 0, canvas.width, canvas.height); //Draws a circle canvasContext.beginPath(); canvasContext.fillStyle = 'yellow'; canvasContext.arc(800, 400, 400, 400, 2 * Math.PI, true); canvasContext.fill(); //draws head canvasContext.beginPath(); canvasContext.fillStyle = 'white'; canvasContext.arc(600, 200, 100, 100, 2 * Math.PI, true); canvasContext.fill(); //draws eye1 canvasContext.beginPath(); canvasContext.fillStyle = 'white'; canvasContext.arc(1000, 200, 100, 100, 2 * Math.PI, true); canvasContext.fill(); //draws eye2 canvasContext.fillStyle = 'black'; canvasContext.fillRect(580, 175, 50, 50); //draws pupil1 canvasContext.fillStyle = 'black'; canvasContext.fillRect(980, 175, 50, 50); //draws pupil2 canvasContext.fillStyle = 'black'; canvasContext.fillRect(650, 550, 300, 6.5); //draws mouth function changingImg() { document.getElementById("y").src = "hand.jpg" } } </script>

Is there anyway to fix this?

Answer 1

I'm assuming <script type="text/javascript" src="hand.jpg"></script> was a small mistake as it should be <script type="text/javascript" src="someFile.js"></script> . But if you were to make a JS file and link to it like that you would probably want to remove the plain <script> tag below.

Moving on, if you wanted to change the size of the image you can simply change the .width and .height property of the element variable.

For example:

var image = document.getElementById('y');

image.width = 1920; // Sets image's width to 1920
image.height = 1080; // Set's image's height to 1080

If you wanted to read the width and height values you can do so like this:

var image = document.getElementById('y');
var imageWidth = image.width; // Image's width
var imageHeight = image.height; // Image's height
