Loop through the pixels of an image and get/change the pixel colour in JavaScript
<p>Is is possible to get and set each pixel colour on a image? </p>

<p>I have an image that is made up of areas with solid colours and depending on what colour the user passes in, I want to update the colours.</p>

<p>I know you can do this with canvas but the app needs to be compatible with ie7 and 8. excanvas does not support the canvas function to get the image data so I am really stuck.</p>

<p>Is it possible to do this solely with JavaScript?</p>
