You need to go to a site like www.vworker.com so that you could hire a programmer to do this work for you.

Pardon me for my laziness..I worked on my requirements and met them finally...
For keeping the origin static to 0,0 i removed the translate before drawing the image however the position of my drawing(pencil tool) is not maintained after zooming the canvas.If i put translate method image is not drawn from 0,0 and if its removed the drawings position is not maintained...crap
Please check my updated code at http://turbofeedback.com/account/demo.htm
