with Android

Hi

When we use it with Android, and Magnify the canvas,
it does not work, I could not draw any line on canvas.
but if I go back 100% display , it work.
Do you have any reason ?

instead of this code,

x = event.touches[0].pageX - $canvas.offset().left; + borderLeftWidth;
y = event.touches[0].pageY - $canvas.offset().top; + borderTopWidth;

I wrote this.

var e = event;
var el=e.target, c=el;

var x=e.touches[0].pageX, y=e.touches[0].pageY;
do {
x -= el.offsetLeft;
y -= el.offsetTop;
el = el.offsetParent;
} while (el);

I worked at good when Android browser zooming.
