Hello,

I have a tool similar to paint where users can draw different shapes on canvas.The canvas is placed inside a div which has background image.The canvas is positioned in such a way that it gives user feel of marking on the image itself.
Now i have to add zooming functionality to my tool where the user can zoom in the picture and do the markings.Can anyone point me to right link to achieve this
