imaqLineGaugeTool2

Usage

int imaqLineGaugeTool2(const Image* image, Point start, Point end, LineGaugeMethod method, const EdgeOptions* edgeOptions, const CoordinateTransform2* transform, float* distance);

Measures the distance between selected edges of a line with high-precision subpixel accuracy.

IMAQ_IMAGE_U8, IMAQ_IMAGE_I16, IMAQ_IMAGE_SGL

Name	Type	Description
image	const Image*	The image in which the function measures the distance between edges.
start	Point	The starting point of the line.
end	Point	The ending point of the line.
method	LineGaugeMethod	The measurement method.
edgeOptions	const EdgeOptions*	Describes how you want the function to find edges. If you set method to IMAQ_POINT_TO_POINT, the function ignores edgeOptions. If you set method to anything other than IMAQ_POINT_TO_POINT, this parameter is required and cannot be NULL.
transform	const CoordinateTransform2*	An optional specification of the coordinate transform for the line. This parameter specifies how to transform the location of the edge detection based on the difference between the reference coordinate system and the measurement coordinate system. Set this parameter to NULL if you do not need to transform the line.
distance	float*	On return, the distance between edges and/or points. This parameter is required and cannot be NULL.

Type	Description
int	On success, this function returns a non-zero value. On failure, this function returns 0. To get extended error information, call imaqGetLastError().
