LAnnProtractor::GetPoints

#include "ltwrappr.h"

virtual L_INT LAnnProtractor::GetPoints(pPoints)

Fills the specified array of ANNPOINT structures with the endpoints of the ruler object.

Parameters

pANNPOINT pPoints

Pointer to the array to be filled with the vertices of the protractor object.

Returns

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

Comments

The ANNPOINT structure is like a Windows POINT structure, except that it uses double-precision floating point values.

Coordinates of an object's points are relative to its container object. The coordinates are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.

The order of the vertices in the array is shown below:
