PSScaling Struct Reference
[Channel Ports Suite Callbacks (DEPRECATED Standard Suite)]

#include <PIGeneral.h>

Detailed Description

Provide a scaling through a rectangle in source space and a corresponding rectangle in destination space.

Equal rectangles result in a direct, unscaled, mapping. Unequal rectangles can be used to up- or down-sample.

For example, if sourceRect is a 100-pixel square in source space: 

sourceRect.top = 0;  sourceRect.left = 0;
sourceRect.bottom = 100;  sourceRect.right = 100;
and destinationRect is a 50-pixel square in destination space: 
destinationRect.top = 0;  destinationRect.left = 0;
destinationRect.bottom = 50;  destinationRect.right = 50;
the scaling indicates to down-sample the image by half.
