Can I have multiple Canvases on an HTML 5 Page with an image on each of the Canvas. I basically need to make use of the JS manipulation Plugin on all the images for my app and this plugin requires the image to be on the canvas.
Will having multiple canvas and an image inside them, affect or slow the performance of the page?
Yes you can have multiple canvas-elements. The performance of your page will not suffer from the fact that there are multiple canvases. What will affect your performance is the redrawing of the canvases. As for the images what will determine the performance is how much redrawing that has to be done.
