RemapImageToLogPolarSpace

Remap an image to log-polar space.
Can use available TwinCAT Job Tasks for executing parallel code regions.

Syntax

Definition:

HRESULT RemapImageToLogPolarSpace(
    HRESULT                hrPrev,
    ITcVnImage*            ipSrcImage,
    ITcVnImage*&           ipDestImage,
    TcVnPoint2_REAL&       aCenter,
    double                 fScale = 0,
    ETcVnInterpolationType eInterpolationType = IT_BILINEAR,
    LONG                   nDestWidth = -1,
    LONG                   nDestHeight = -1
)

Parameters

Name	Type	Default	Description
hrPrev	HRESULT		HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
ipSrcImage	ITcVnImage*		Source image
ipDestImage	ITcVnImage*&		Destination image (Must not be the same as ipSrcImage! An appropriate destination image will be created if required.)
aCenter	TcVnPoint2_REAL&		Center point for the transformation
fScale	double	0	Magnitude scale parameter, i.e. image width / ln(radius) (set to 0 for auto select)
eInterpolationType	ETcVnInterpolationType	IT_BILINEAR	Interpolation type
nDestWidth	LONG	-1	Destination image width (set to -1 for source image width, 0 to auto scale to transformed radius, > 0 for a user defined width)
nDestHeight	LONG	-1	destination image height (set to -1 for source image height, 0 to auto scale to transformed radius * PI, > 0 for a user defined height)
