我创建一个图像对象，我才得以放大。 但图像只能在考虑到图像的中心。 所以我怎么可以放大手势??

  picture.addEventListener（TransformGestureEvent.GESTURE_ZOOM，onZoom）;

功能onZoom（E：的TransformGestureEvent）{
    picture.scaleX * =（e.scaleX + e.scaleY）/ 2;
    picture.scaleY * =（e.scaleX + e.scaleY）/ 2;
}
 

解决方案

试试这个...

 进口flash.events.TransformGestureEvent;
进口flash.ui.Multitouch;
进口flash.ui.MultitouchInputMode;
进口fl.motion.MatrixTransformer;

Multitouch.inputMode = MultitouchInputMode.GESTURE;
stage.addEventListener（TransformGestureEvent.GESTURE_ZOOM，onZoom）;
功能onZoom（事件：的TransformGestureEvent）：无效
{
    //trace(e.localX）;
    VAR locX：数= event.localX;
    VAR locY：数= event.localY;
    VAR STX：数= event.stageX;
    VAR麦粒肿：数= event.stageY;
    VAR prevScaleX：数= gambar.scaleX;
    VAR prevScaleY：数= gambar.scaleY;
    VAR垫：矩阵;
    VAR externalPoint =新的点（STX，STY）;
    VAR internalPoint =新的点（locX，locY）;

    gambar.scaleX * = event.scaleX;
    gambar.scaleY * = event.scaleY;

    如果（event.scaleX→1＆安培;＆安培; gambar.scaleX→6）{
    gambar.scaleX = prevScaleX;
    gambar.scaleY = prevScaleY;
    }

    如果（event.scaleY→1＆安培;＆安培; gambar.scaleY→6）{
    gambar.scaleX = prevScaleX;
    gambar.scaleY = prevScaleY;
    }

    如果（event.scaleX＆LT; 1.1＆安培;＆安培; gambar.scaleX＆LT; 1）{
    gambar.scaleX = prevScaleX;
    gambar.scaleY = prevScaleY;
    }

    如果（event.scaleY＆LT; 1.1＆安培;＆安培; gambar.scaleY＆LT; 1）{
    gambar.scaleX = prevScaleX;
    gambar.scaleY = prevScaleY;

    }
    垫= gambar.transform.matrix.clone（）;
    MatrixTransformer.matchInternalPointWithExternal（垫，internalPoint，externalPoint）;
    gambar.transform.matrix =垫;
}

gambar.addEventListener（的MouseEvent.MOUSE_DOWN，f_begin）;
gambar.addEventListener（侦听MouseEvent.MOUSE_UP，f_end）;
功能f_begin（E：MouseEvent）方法：无效
{
    gambar.startDrag（）;
}
功能f_end（E：MouseEvent）方法：无效
{
    gambar.stopDrag（）;
}
 

顺便说一句你的PIC是太可爱了..：D

I create an image object and I was able to enlarge . but images can only be in view of the center of the image . so how I can enlarge the image of the point of the gesture ??

picture.addEventListener(TransformGestureEvent.GESTURE_ZOOM, onZoom);

function onZoom(e:TransformGestureEvent){
    picture.scaleX *= (e.scaleX+e.scaleY)/2;
    picture.scaleY *= (e.scaleX+e.scaleY)/2;
}

Try this...

import flash.events.TransformGestureEvent;
import flash.ui.Multitouch;
import flash.ui.MultitouchInputMode;
import fl.motion.MatrixTransformer;

Multitouch.inputMode = MultitouchInputMode.GESTURE;
stage.addEventListener(TransformGestureEvent.GESTURE_ZOOM , onZoom);
function onZoom(event:TransformGestureEvent):void
{
    //trace(e.localX);
    var locX:Number=event.localX;
    var locY:Number=event.localY;
    var stX:Number=event.stageX;
    var stY:Number=event.stageY;
    var prevScaleX:Number=gambar.scaleX;
    var prevScaleY:Number=gambar.scaleY;
    var mat:Matrix;
    var externalPoint=new Point(stX,stY);
    var internalPoint=new Point(locX,locY);

    gambar.scaleX *= event.scaleX;
    gambar.scaleY *= event.scaleY;

    if(event.scaleX > 1 && gambar.scaleX > 6){
    gambar.scaleX=prevScaleX;
    gambar.scaleY=prevScaleY;
    }

    if(event.scaleY > 1 && gambar.scaleY > 6){
    gambar.scaleX=prevScaleX;
    gambar.scaleY=prevScaleY;
    }

    if(event.scaleX < 1.1 && gambar.scaleX < 1){
    gambar.scaleX=prevScaleX;
    gambar.scaleY=prevScaleY;
    }

    if(event.scaleY < 1.1 && gambar.scaleY < 1){
    gambar.scaleX=prevScaleX;
    gambar.scaleY=prevScaleY;

    }
    mat=gambar.transform.matrix.clone();
    MatrixTransformer.matchInternalPointWithExternal(mat,internalPoint,externalPoint);
    gambar.transform.matrix=mat;
}

gambar.addEventListener(MouseEvent.MOUSE_DOWN, f_begin);
gambar.addEventListener(MouseEvent.MOUSE_UP, f_end);
function f_begin(e:MouseEvent):void
{
    gambar.startDrag(); 
}
function f_end(e:MouseEvent):void
{
    gambar.stopDrag();
}

btw your pic is so cute.. :D
