Sets the length of the gauge (the perpendicular lines at the ends of the Ruler object).
virtual L_INT LAnnRuler::SetGaugeLength(dLength, uFlags=0)
The new length of the ruler object's gauge.
Flags that determine the object to process. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:
|0||Process only the specified object.|
|ANNFLAG_SELECTED||[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions.|
|ANNFLAG_NOINVALIDATE||[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
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.
For an example, refer to LAnnRuler::GetGaugeLength.
