Method Detail

scale

public BitmapImagePixels scale(BitmapImagePixels original,
                               double scaling)

Scales a bitmap image by copying the nearest neighbor pixel of the original. As a result some pixels just dropped.

Specified by:

scale in interface IScalingAlgorithm

Parameters:

original - is an image to scale presented as BitmapImagePixels

scaling - is a scaling coefficient. Should be in (0, 1] range

Returns:

scaled image
