Adds a new vector object to the class object's layer. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
pVectorObject	Pointer to an LVectorObject object that references the vector object to add.

Returns

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

Example

This example will add a new red line to the Active Layer LVectorBase object.

L_INT LVectorLayer__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 active layer 
   LVectorLayer VectorLayer; 
   nRet = pVector->GetActiveLayer(&VectorLayer); 
   if(nRet != SUCCESS) 
      return nRet; 
   nRet = VectorLayer.AddObject(&VectorLine ); 
   if(nRet != SUCCESS) 
      return nRet; 
   //LVectorLine destructor called when VectorLine goes out of scope 
   return SUCCESS;
