LAnnotation::GetOffsetX

#include "ltwrappr.h"

virtual L_DOUBLE LAnnotation::GetOffsetX()

Gets the X offset of the annotation object.

Returns

The specified object's X offset.

Comments

Typically, this value is used to match the root container's offset to the offset of the associated bitmap's display rectangle.

The offset values are applied after the scalar properties, which are set by the LAnnotation::SetScalarX and LAnnotation::SetScalarY functions. For more information, refer to Low-Level Coordinate System for Annotations.
