How to beginBitmapFill without repeats?(AS3) - actionscript-3

Question

my code:
myCircle = new Shape();
function doStuffWithBitmapData(bmd:BitmapData):void
{
myCircle = new Shape();
var matrix:Matrix = new Matrix();
matrix.translate(0, 0);
myCircle.graphics.beginBitmapFill(bmd, matrix, false);
myCircle.graphics.drawCircle(0, 0, 17);
myCircle.graphics.endFill();
myCircle.x = 40;
myCircle.y = 63;
addChild(myCircle);
// your code
addEventListener(Event.ENTER_FRAME, onEnterFrame);
}
private function onEnterFrame(e:Event)
{
myCircle.rotation += 3;
}
I need to fill the circle with image , but the image is repeating many times, but if I set the repeat to false, the picture will be bigger, can I make no repeat and at the same time don't change the sizes of the filled image?

Answer 1

i'm not too sure of the the bitmapfill method, but creating your own bitmap and bitmapData, and then using your image's bitmapdata, you can manipulate the image pixel/data anyway you like.
-Using the setPixel/setPixel32 method of the bitmapData class will be helpful in your task (google is your friend)

Please look closely at the draw() method of BitmapData Class Documents. It is very important.
and refer a following code.
import flash.display.BitmapData;
import flash.display.Shape;
import flash.display.Bitmap;
var myCircle:Shape;
var bmd:BitmapData = new BitmapData(600,400,false,0xffffff);
var bmp:Bitmap = new Bitmap(bmd);
this.addChild(bmp);
var circleBitmapData:BitmapData = new BitmapData(20,20,false,0xffffff * Math.random());
myCircle = new Shape();
var matrix:Matrix = new Matrix();
myCircle.graphics.beginBitmapFill(circleBitmapData);
myCircle.graphics.drawCircle(0, 0, 20);
myCircle.graphics.endFill();
myCircle.x = 40;
myCircle.y = 63;
addEventListener(Event.ENTER_FRAME, onEnterFrame);
function onEnterFrame(e:Event)
{
bmd.draw(myCircle, myCircle.transform.matrix, myCircle.transform.colorTransform);
myCircle.x = Math.random() * stage.width;
myCircle.y = Math.random() * stage.height;
}
