WPF

Hello Every One, I have a Critical Problem in my WPF Ink Canvas. The Problem is , when i draw something on it using mouse move , it draws easily , but when my application run on other system, which have 1280*720 screen Resolution, that time Ink canvas draws shape outside the drawing area and the shape is not visible also.

my development Machine  screen Resolution - 1680*1050 and when i run this application on low level Resolution Machines then Ink canvas drawing area expand and shapes are draw outside the canvas , and they are not visible also. I already tried the viewbox control, but i am not getting which i want. 

Please solve this Problem as soon as possible if anyone have the solution of It.
