Inputs

Name	Type	Description
ipSrcImage	ITcVnImage	Source image
ipDestImage	Reference To ITcVnImage	Destination image (Must not be the same as ipSrcImage! An appropriate destination image will be created if required.)
fScale	LREAL	Magnitude scale parameter, i.e. image width / ln(radius) (set to 0 for auto select)
eInterpolationType	ETcVnInterpolationType	Interpolation type
nDestWidth	DINT	Destination image width (set to -1 for source image width, 0 to auto scale to transformed radius, > 0 for a user defined width)
nDestHeight	DINT	destination image height (set to -1 for source image height, 0 to auto scale to transformed radius * PI, > 0 for a user defined height)
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

In/Outputs

Name	Type	Description
aCenter	TcVnPoint2_REAL	Center point for the transformation
