Slice images with a Matrix

For my current project I needed something to slice an image easily, first I tried to slice the image with a mask, but I soon found out that this much heavier than my current solution.
Below is the end result I needed to have (the triangle is a big mask).
// image = a MovieClip with an image // upper part var upperBitmapData:BitmapData = new BitmapData(image.width,image.height / 2); upperBitmapData.draw(image); mUpperBitmap = new Bitmap(upperBitmapData); addChild(mUpperBitmap); //lowerpart var lowerMatrix:Matrix = new Matrix(); lowerMatrix.ty = -(image.height / 2); var lowerBitmapData:BitmapData = new BitmapData(image.width,image.height / 2); lowerBitmapData.draw(image,lowerMatrix); mLowerBitmap = new Bitmap(lowerBitmapData); mLowerBitmap.y = ContentClip.MASK_HEIGHT / 2; addChild(mLowerBitmap); image = null;
