LAnnCurve::SetPoints
#include "ltwrappr.h"
virtual L_INT LAnnCurve::SetPoints(pPoints, uCount)
pANNPOINT pPoints; |
/* pointer to the array of LEADTOOLS ANNPOINT structures*/ |
L_UINT uCount; |
/* number of points in the array */ |
Defines the shape of the annotation object. This function is available in the Document/Medical Toolkits.
Parameter |
Description |
pPoints |
Pointer to the array of LEADTOOLS ANNPOINT structures that specifies the shape 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, which must be in the order in which the vertices are connected. To define the line that closes a polygon, the last point in the array is connected to the first point of the array.
Alternatively, you can use the LAnnotation::Define function to specify the array of points interactively.
