Blending pixels from Two Bitmaps

Question

I\'m beating my head against a wall here, and I\'m fairly certain I\'m doing something stupid, so time to make my stupidity public.

I\'m trying to take two images, b

Simple overlay you can do this way (for simplicity it is supposed that bmp1 is equal or bigger than bmp2):

private Bitmap bitmapOverlay(Bitmap bmp1, Bitmap bmp2) 
{ 
    Bitmap bmOverlay = Bitmap.createBitmap(bmp1.getWidth(), bmp1.getHeight(), bmp1.getConfig()); 
    Canvas canvas = new Canvas(bmOverlay); 
    canvas.drawBitmap(bmp1, 0, 0, null);
    canvas.drawBitmap(bmp2, 0, 0, null);
    return bmOverlay; 
} 

For more complex blending algorithms, maybe you can help yourself with some available Bitmap/Canvas functions.
