[C#]	public void affineTransform(double a, double b, double c, double d, double e, double f [, int bgColor [, int filter [, double blur ]]]);

Perform affine transformation on the drawing surface.

An affine transformation is an operation where every pixel is copied to another pixel according to the formula.


where (xSrc, ySrc) is a source pixel, and (xDest, yDest) is where it should go to.

Many graphics operation, such as translation, rotation, and resizing, can be considered as a special case of affine transformation.

Argument	Default	Description
a	(Mandatory)	The parameter 'a' in the coordinate transformation formula "xDest = a * xSrc + b * ySrc + c".
b	(Mandatory)	The parameter 'b' in the coordinate transformation formula "xDest = a * xSrc + b * ySrc + c".
c	(Mandatory)	The parameter 'c' in the coordinate transformation formula "xDest = a * xSrc + b * ySrc + c".
d	(Mandatory)	The parameter 'd' in the coordinate transformation formula "yDest = d * xSrc + e * ySrc + f".
e	(Mandatory)	The parameter 'e' in the coordinate transformation formula "yDest = d * xSrc + e * ySrc + f".
f	(Mandatory)	The parameter 'f' in the coordinate transformation formula "yDest = d * xSrc + e * ySrc + f".
bgColor	FFFFFF	The background color used to fill destination pixels that are not mapped to any source pixels.
filter	LinearFilter	The filter to use for re-sampling.
blur	1	The blur factor to use for re-sampling.
