Screenshot downsampling: Comparison of some Sample-Algorithms

In this example, let's compare all eight different sample-algorithms when downsampling a screenshot.
In this case: The german google website. You find the Original-Image here.
The screenshots was sampled from 800 x 600 to 500 x 360 pixel.

For some personal notes, scoll down.

Nearest Neighbour

Bilinear

Lanczos

Hermite

Gaussian

Bspline

Bell

Mitchell

Personal notes:

Non of the tested algorithms are good when scaling down the screenshot!
"Nearest Neighbour" is absolutely unusable.

Maybe Lanczos is the only one with a result, most people can live with.
