I have images that can be enlarged ... but the image is enlarged from the center of the image, instead of the center of the stage.... how to keep the image can be enlarged from the center stage not from center image ?

}

Answer 1

This is my simple code..

zoomin.addEventListener(MouseEvent.CLICK, f_zoomin);
function f_zoomin(e:MouseEvent)
{
    zoom = 1;
    f_zoom();
}
zoomout.addEventListener(MouseEvent.CLICK, f_zoomout);
function f_zoomout(e:MouseEvent)
{
    zoom = -1;
    f_zoom();
}
function f_zoom()
{
    var coord:Point = map.globalToLocal(new Point(stage.stageWidth/2, stage.stageHeight/2));
    map.scaleX += zoom;
    map.scaleY += zoom;
    map.x = ((2 * stage.stageWidth/2) - (2 * (coord.x * map.scaleX))) / 2;
    map.y = ((2 * stage.stageHeight/2) - (2 * (coord.y * map.scaleY))) / 2;
}

Btw your pic like my girlfriend.. LOL :D
