Inputs

Name	Type	Description
ipSrcImage	ITcVnImage	Source image (USINT, 1 channel)
ipDestImage	Reference To ITcVnImage	Destination image (USINT, 1 channel. x: position, y: intensity, origin: bottom left. An appropriate destination image will be created if required.)
nScaleX	DINT	Scale in x direction (ipDestImage will have a width of nScaleX * (ipSrcImage width - 1) + 1)
nScaleY	DINT	Scale in y direction (ipDestImage will have a height of nScaleY * 255 + 1)
nThickness	DINT	Line thickness
nDestChannels	DINT	ipDestImage channels (1 or 3)
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

In/Outputs

aStartPoint	TcVnPoint2_REAL	Start point of the line segment
aEndPoint	TcVnPoint2_REAL	End point of the line segment
aBackgroundColor	TcVnVector4_LREAL	Background color
aLineColor	TcVnVector4_LREAL	Line color
aGridColor	TcVnVector4_LREAL	Grid color
