Detailed Description

get a pyramid image.

A image pyramid is a image in multiple resolutions. Usually it is used to accelerate image processing, by using lower resolutions first. they are properly low pass filtered, so no undersampling occurs (it would if one just takes every 2^level pixel instead).

Parameters

filename	of source image
level	of pyramid. height and width are calculated as follows: height/(level^2), width/(level^1)
