Detailed Description

Perspective transformation coefficients.

Performed calculation is:

X = (C00*X' + C01*Y' + C02) / (C20*X' + C21*Y' + C22)

Y = (C10*X' + C11*Y' + C12) / (C21*X' + C21*Y' + C22)

rightTop	Right top corner's coordiante in the source image.
rightBottom	Right bottom corner's coordinate in the source image.
leftBottom	Left bottom corner's coordinate in the source image.
destRect	Rectangle containing the positions into which the input points are to be converted.

PerspectiveTransformation() [2/2]

PerspectiveTransformation	(	Point2Dd	leftTop,
		Point2Dd	rightTop,
