Hi Simon,
I was wondering if you could point me in the right direction to solve the coordinate problems if I place this in a smaller div with scrollbars. It works if you are scrolled to the top left but any scrolling seems to affect the mouse coordinates.
`
!DOCTYPE html>
html>
head>
style>
#container{
width: 300px;
height: 300px;
overflow-y: scroll;
}
/style>
/head>
body>
div id="container">canvas id="canvas1" style="border: 1px solid black;" width="600" height="1200">br />
This text is displayed if your browser does not support HTML5 Canvas.br />
/canvas>/div>
script src="https://simonsarris.com/project/canvasdemo/shapes.js"></script>
script>
init();
/script>
/body>
/html>
`
Thanks in advance.

In your code i see this code bellow to clear canvas
this.ctx.clearRect(0, 0, this.width, this.height);
How i can use background image instead using white background?
