IMAQ Get Contour Info VI

Contour Image is a reference to the image containing a contour.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Has Fitted Equation specifies whether the contour has a fitted equation. If TRUE, the contour has a fitted equation. If FALSE, the contour does not have a fitted equation.

Contour Image Out (dup) is a reference to the image containing a contour.

Points (pixel) specifies the location of every point detected on the curve, in pixels.

	X is the x-coodrdinate of the point.
	Y is the y-coodrdinate of the point.

Curvature Profile (pixel) displays the curvature profile for the selected contour, in pixels.

Length (pixel) specifies the length, in pixels, of the curves in the image.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Points (real) specifies the location of every point detected on the curve, in calibrated units.

	X is the x-coodrdinate of the point.
	Y is the y-coodrdinate of the point.

Curvature Profile (real) displays the curvature profile for the selected contour, in calibrated units.

Length (real) specifies the length, in calibrated units, of the curves within the curvature range.
