LAnnProtractor::SetPoints

#include "ltwrappr.h"

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

pANNPOINT pPoints;	/* pointer to an array */
L_UINT uCount;	/* number of points in the array */

Defines the vertices of the protractor object.

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

Returns

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:
