Problem panning on iPad 4 about gestouch

Well it sounds like it's related to retina. What's the size of your view and what's the size of the stage? Maybe view is scaled twice in terms of width and height? If so you need to transform offsets (using view.globalToLocal).

Thanks a lot for your response and help. Unfortunately, I am not that good with matrix operations or positioning in general when it comes to different devices and DPIs. I tried changing the code by adding

var globalPoint:Point =   globalToLocal(new Point(gesture.offsetX, gesture.offsetY));
matrix.translate(globalPoint.x, globalPoint.y);

but I am still not getting the correct results. I did however notice when I change the application DPI from 160 to 240 everything works as expected on the retna display.

Here is the info I am getting for the stage and view dimensions:
Stage: 1536 x 2008
View: 1024 x 1293.66

Thanks again, sorry if this post does not belong here because I think it is an issue on my end and not with your code.

Well it's a common task, and I should actually add it to examples project.
Haven't tested, but I think it should work:

public static const ZERO_POINT:Point = new Point();// define somewhere

private var globalOffset:Point = new Point();//reuse same instance for better performance
globalOffset.x = gesture.offsetX;
globalOffset.y = gesture.offsetY;
var offsetInThis:Point = this.globalToLocal(globalOffset).subtract(this.globalToLocal(ZERO_POINT));

upd: I would include this functionality in gestures of course, BUT since architecture is not only about flash.display::DisplatObject anymore... This is not that hard to transform stuff after all.

It is working like a charm! Thanks a ton, both for your help with my problem and for your great work on this library and providing them to us for use!
