GaussianFilter

Apply a Gaussian filter to smooth the image.
Can use available TwinCAT Job Tasks for executing parallel code regions.

Syntax

Definition:

HRESULT GaussianFilter(
    HRESULT                        hrPrev,
    ITcVnImage*                    ipSrcImage,
    ITcVnImage*&                   ipDestImage,
    ULONG                          nFilterWidth,
    ULONG                          nFilterHeight,
    double                         fSigmaX = 0,
    double                         fSigmaY = 0,
    ETcVnBorderInterpolationMethod eBorderType = BIM_DEFAULT
)

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 (An appropriate destination image will be created if required.)
nFilterWidth	ULONG		Filter width in pixels (1, 3, 5, 7, ...)
nFilterHeight	ULONG		Filter height in pixels (1, 3, 5, 7, ...)
fSigmaX	double	0	Gaussian kernel standard deviation in X direction (>= 0, automatically chosen if 0)
fSigmaY	double	0	Gaussian kernel standard deviation in Y direction (>= 0, automatically chosen if 0)
eBorderType	ETcVnBorderInterpolationMethod	BIM_DEFAULT	Image border handling
