LAnnotation::SetRect

#include "ltwrappr.h"

virtual L_INT LAnnotation::SetRect(pRect)

/* pointer to a LEADTOOLS ANNRECT structure */

Sets the defining rectangle of the annotation object. This function is available in the Document/Medical Toolkits.

Parameter	Description
pRect	Pointer to the LEADTOOLS ANNRECT structure that specifies the container. The ANNRECT structure is like a Windows RECT structure, except that it uses double-precision floating point values.
	Coordinates of an object's rectangle 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.

Returns

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

Comments

You can use this function to set the dimensions of an annotation object, such as a rectangle or ellipse, that is defined by a rectangle. For polygonal objects, you can use the LAnnPolygon::SetPoints or LAnnPolygon::Define function.

The coordinates of the rectangle are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.

Example

L_VOID TestAnnRect(LAnnotation& LeadAnn)
{
   ANNRECT  AnnRect ;
   LeadAnn.BringToFront();
   LeadAnn.GetRect(&AnnRect) ;

   LeadAnn.Move((AnnRect.right - AnnRect.left) / 20,
      (AnnRect.bottom - AnnRect.top) / 20, 0);

   //...
   //...

   AnnRect.left += 20 ;
   AnnRect.top += 20 ;
   AnnRect.right += 20 ;
   AnnRect.bottom += 20 ;

   LeadAnn.SetRect(&AnnRect) ;
   LeadAnn.SendToBack() ;
