Fastest way to draw bitmaps?

[Steph David]

I need to select the fastest way to draw an Image in a graphics.

I have several methods, and I'd like to know if someone made some test to find the best one.

I can use bmp or gif as source image.
I can use Display or Pixel for the PageUnit.
If I use Display, then I need to use DrawImage(Image, X, Y, Width, Height).
If I use Pixel, I can use DrawImageUnscaled(Iamge, X, Y).

I think the best is to use Pixel, with DrawImageUnscaled.

Anyone with metrics aboutt that?
