LVectorGroup::AddObject

Summary

Adds a new vector object to a class object's group.

This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Syntax

#include "ltwrappr.h"

virtual L_INT LVectorGroup::AddObject(pVectorObject)

Parameters

LVectorObject * pVectorObject

Pointer to an LVectorObject object that references the vector object to add.

Returns

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

Comments

Example

This example will add a new red line to the first Group in an LVectorBase object.

L_INT LVectorGroup__AddObjectExample(HWND hWnd, LVectorBase *pVector) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
 
   L_INT       nRet; 
   VECTORLINE  Line; 
 
   //Create Line Object    
   Line.Point[ 0 ].x = 50.0; 
   Line.Point[ 0 ].y = 50.0; 
   Line.Point[ 0 ].z =  0.0; 
 
   Line.Point[ 1 ].x =  70.0; 
   Line.Point[ 1 ].y =  50.0; 
   Line.Point[ 1 ].z =   0.0; 
 
   Line.Pen.nSize = sizeof( VECTORPEN ); 
 
   Line.Pen.bExtPen = FALSE; 
   Line.Pen.NewPen.LogPen.lopnStyle = PS_SOLID; 
   Line.Pen.NewPen.LogPen.lopnWidth.x = 10; 
   Line.Pen.NewPen.LogPen.lopnWidth.y = 10; 
   Line.Pen.NewPen.LogPen.lopnColor = RGB(255,0,0); 
 
   LVectorLine VectorLine(&Line); 
 
   // add to current group 
   LVectorGroup VectorGroup; 
 
   nRet = pVector->GetGroupByIndex(0, &VectorGroup); 
   if (nRet == SUCCESS) 
   { 
      VectorGroup.AddObject(&VectorLine ); 
   } 
   else 
      return nRet; 
 
   //LVectorLine destructor called when VectorLine goes out of scope 
 
   return SUCCESS;
