Import an image into the flash
convert to movieclip
give identifier as sample

and here is the code

var img:sample = new sample();
addChild(img);

img.x = stage.stageWidth/2;
img.y = stage.stageHeight/2;

img.filters = [new ColorMatrixFilter([-1, 0, 0, 0, 255, 0, -1, 0, 0, 255, 0, 0, -1, 0, 255, 0, 0, 0, 1, 0])];

package druva {

 import flash.display.*;

 public class drawEllipse extends Sprite {

 public function drawEllipse() {
 var canvas:Shape = new Shape(  );
 canvas.graphics.lineStyle(3, 0xFF0000);
 canvas.graphics.drawEllipse(0,0,100,50);
 addChild(canvas);

 }
 }
