LAnnProtractor::SetPoints

#include "ltwrappr.h"

virtual L_INT LAnnProtractor::SetPoints(pPoints, uCount=3)

Defines the vertices of the protractor object.

Parameters

pANNPOINT pPoints

Pointer to the array of LEADTOOLS ANNPOINT structures that specifies the vertices of the annotation.

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.

L_UINT uCount

The number of points in the array that you specify in the pPoints parameter.

Returns

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

Comments

You call this function once, passing an array of points.

When setting the points of a protractor in the array, the vertices must be given in a specific order. The order of the vertices in the array is shown below:
