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:
