Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipImage

ITcVnImage*

Source image

aMaxValue

TcVnVector4_LREAL&

Returns the maximum pixel value

aPosition

TcVnPoint2_DINT&

Returns the first found position of aMaxValue (not supported for multi-channel images with ELEMENTWISE)

ipMask

ITcVnImage*

nullptr

Optional mask to specify which pixel positions are considered (USINT, set parameter to 0 if not required)

eVectorCompareMethod

ETcVnVectorCompareMethod

VCM_EUCLIDEAN

Select a vector compare method for multi-channel images
