javascript - How to speed up panning and zooming using smoothZoom jquery plugin?

Question

Hello I am currently using the smoothZoom plugin in a project (http://codecanyon.net/item/smooth-zoom-pan-jquery-image-viewer/511142). I have to load in an image of roughly 2500 * 2500 pixels (the client is insistant on this size not being changed otherwise I would just resize the image).

Does anybody know any ways to make the panning and zooming smoother?

At the moment the operation of the smoothZoom is very sluggish.

Answer 1

In my opinion, what causes the operation of the smoothZoom to be sluggish is the client's hardware & browser. Not the plugin itself. 2500x2500 is a very large image, and the rendering of any animation can cause heavy usage of CPU.
