    BlendMode and drawing circles.

    flexlearner10001

      Hello,

       

      I have a bitmap image that is a solid color.  Created like this.

       

      var bmd:BitmapData = new BitmapData(500, 500, false, 0x0000FF);

       

      What im trying to do is cut transparent circles into it before I draw it to my UIComponent from an array of Points like.

       

      for (var i:uint; i < circleArray.length; i++) {

          //cut circle width radius of 30 pixels at point circleArray[i].x,circleArray[i].y

      }

       

      then finally draw it to my UIComponent

       

      graphics.beginBitmapFill(bmd, null, false);

      graphics.drawRect(0, 0, bmd.width, bmd.height);

      graphics.endFill();

       

      But I have no clue really how to do this.  I believe I need to use blending, but I only see a rectangle.  What is the best way to do this? Thank you
