Bounds 3 Ways

By Zevan | May 21, 2009

CLICK HERE TO COPY
Actionscript:

// make a complex poly and position it randomly

var poly:Sprite = Sprite(addChild(new Sprite()));

poly.graphics.lineStyle(3, 0xFF0000);

poly.graphics.beginFill(0x00FF00);

for (var i:int = 0; i<10; i++) {

    poly.graphics.lineTo(Math.random()*100 - 50, Math.random()*100 - 50);

}

poly.x=Math.random()*stage.stageWidth;

poly.y=Math.random()*stage.stageHeight;

 

// get bound information:

 

// is in pixels (whole numbers)

trace("pixelBounds: ", poly.transform.pixelBounds);

// doesn't include stroke width

trace("getBounds: ", poly.getBounds(this));

// includes stroke width

trace("getRect: ", poly.getRect(this));

Three different ways to [...]

Actionscript:

var size:Number = 800;

var canvas:BitmapData = new BitmapData(size,size,false, 0x000000);

addChild(new Bitmap(canvas, "auto", true));

 

scaleX = scaleY = .5;

var pix:Number = size * size;

var scale:Number = 1/(size/3);

 

for (var i:Number = 0; i<pix; i++){

       var xp:Number = (i % size);
