LAnnPolyRuler::SetGaugeLength

#include "ltwrappr.h"

virtual L_INT LAnnPolyRuler::SetGaugeLength(dLength, uFlags)

L_DOUBLE dLength;	/* the new gauge length */
L_UINT uFlags;	/* reserved for future versions */

Sets the length of the gauge (The perpendicular lines at the ends of the Polyruler object).

Parameter	Description
dLength	The new length of the ruler object's gauge.
uFlags	Reserved for future versions, use 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The gauge length property applies only to Automation, PolyRuler, and Ruler objects. Refer to Annotation Automation Object.

dLength is expressed in pixels, not in points. The length is for the whole line, not just from the end point of the ruler to the end point of the gauge - it is from one end of the gauge to the other end of the gauge.
