Move Page left/Right based on Gesture Swipe

I am using a MovieClip Component to load a swf file

I need to know how I can move the screen left or right when the user zooms in.

Dgofman: I am not using scroller because when I did usability testing, users did not like the fact that the page was bouncing around...

My code is as follows:

public function onSwipe(event:TransformGestureEvent):void{
				if ( event.offsetY == -1 ) {
					currentPage = pdfContent.currentFrame + 1;
					pdfContent.gotoAndStop(currentPage);
				}
				else if ( event.offsetY == 1 ) 
				{
					currentPage = pdfContent.currentFrame - 1;
					pdfContent.gotoAndStop(currentPage);
				}
				else if ( event.offsetX == -1 ) 
				{
					
			
				}
				else if ( event.offsetX == 1 ) 
				{
					
				}
			}

protected function pdfHolder_gestureZoomHandler(event:TransformGestureEvent):void
			{
				var zoomFactor:Number = .1;
				if(pdfContent.scaleX < 2){
					pdfContent.scaleX += zoomFactor;
					pdfContent.scaleY += zoomFactor;
				}
				
				if (pdfContent.scaleX > 1){
					pdfContent.scaleX -= zoomFactor;
					pdfContent.scaleY -= zoomFactor;
				}
			}

<mx:UIComponent id="pdfHolder" y="0" width="100%" height="100%"
					gestureZoom="pdfHolder_gestureZoomHandler(event)"
					gestureSwipe="onSwipe(event)"/>

did you try move the child of pdfContent

var child:* = pdfContent.getChildAt(0);
child.x = N;
child.y = N;

This is what I currently have.. it moves but veryyyy little..and only in 1 direction

public function onSwipe(event:TransformGestureEvent):void{
				if ( event.offsetY == -1 ) {
					currentPage = pdfContent.currentFrame + 1;
					pdfContent.gotoAndStop(currentPage);
				}
				else if ( event.offsetY == 1 ) 
				{
					currentPage = pdfContent.currentFrame - 1;
					pdfContent.gotoAndStop(currentPage);
				}
				else if ( event.offsetX == -1 ) 
				{
					pdfContent.x += event.offsetX;
			
				}
				else if ( event.offsetX == 1 ) 
				{
					pdfContent.x -= event.offsetX;
				} 
			}

I need a full code to understand your problem defiantly (+= N) is not a good solution

ok its working fine now

here is updated code

public function onSwipe(event:TransformGestureEvent):void{
				if ( event.offsetY == -1 ) {
					currentPage = pdfContent.currentFrame + 1;
					pdfContent.gotoAndStop(currentPage);
				}
				else if ( event.offsetY == 1 ) 
				{
					currentPage = pdfContent.currentFrame - 1;
					pdfContent.gotoAndStop(currentPage);
				}
				else if ( event.offsetX == -1 ) 
				{
					pdfContent.x -= event.offsetX*-10;
			
				}
				else if ( event.offsetX == 1 ) 
				{
					pdfContent.x += event.offsetX*10;
				} 
			}

That exactly what I am working on, but I wrote differently - multiplying base on scale of context size


pdfContent.x -= event.offsetX * (width / pdfContent.width);

so, that give you the same effect for scrolling large and small content documents more smooth effect
