LAnnRuler::GetGaugeLength

Summary

Gets the length of the gauge (the perpendicular lines at the ends of the Ruler object).

Syntax

#include "ltwrappr.h"

virtual L_DOUBLE LAnnRuler::GetGaugeLength()

Returns

The object's gauge length.

Comments

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

Length 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.

Required DLLs and Libraries

Platforms

Win32, x64.

   /* if gauge length setting for the Automation object  
   is larger than 5 pixels, then make it 5 pixels. */ 
   dLength = pAnnObject->GetGaugeLength();

	{ 
      nRet = pAnnObject->SetGaugeLength( 5.0f, 0);  
		if(nRet != SUCCESS) 
			return nRet;
