Hi everyone,
Having a really weird problem that I would like some input on. I am trying
to draw an image, as well as video, onto canvas. I use the simple code
below:
$(document).ready(function() {
var image = $("#cat").get(0);
var cv = $("#img_container").get(0);
var ctx = cv.getContext('2d');
ctx.drawImage(image, 0, 0);
});
When I load up the HTML page in Chrome absolutely nothing happens and I see
no errors in the JavaScript console. When running it in Firefox 3.6.3 I get
the following error:
uncaught exception: [Exception... "Component returned failure code:
0x80040111 (NS_ERROR_NOT_AVAILABLE)
[nsIDOMCanvasRenderingContext2D.drawImage]" nsresult: "0x80040111
(NS_ERROR_NOT_AVAILABLE)" location: "JS frame ::
file:///C:/thelab/HTML5Canvas/scripts/canvas_img.js
<file:///C:\thelab\HTML5Canvas\scripts\canvas_img.js> :: anonymous :: line
9" data: no]
For The life of me I cannot see what I am doing wrong with the above. I have
done console logs to ensure that the code get's the image as well as the
canvas on the relevant lines and it definitely does. Anything I am
overlooking?
Thank you all in advance,
Schalk
