LVectorBase::AddObject

#include "ltwrappr.h"

virtual L_INT LVectorBase::AddObject(pVectorObject);

pointer to the vector object to add

Adds a new vector object to the class object's active vector 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 green vertex to the Active Layer LVectorBase object. Once added, the color will be changed to blue.

L_INT LVectorBase__AddObjectExample(HWND hWnd, LVectorBase *pVector) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
   L_INT          nRet; 
   VECTORVERTEX   Vertex; 
   //Create Vertex Object 
   Vertex.Point.x = 50; 
   Vertex.Point.y = 50; 
   Vertex.Point.z = 10; 
   Vertex.Pen.bExtPen = FALSE; 
   Vertex.Pen.nSize = sizeof( VECTORPEN ); 
   Vertex.Pen.NewPen.LogPen.lopnStyle = PS_SOLID; 
   Vertex.Pen.NewPen.LogPen.lopnWidth.x = 10; 
   Vertex.Pen.NewPen.LogPen.lopnWidth.y = 10; 
   Vertex.Pen.NewPen.LogPen.lopnColor = RGB(0,255,0); 
   LVectorVertex VectorVertex(&Vertex); 
   nRet = pVector->AddObject(&VectorVertex); 
   if(nRet != SUCCESS) 
      return nRet; 
   //Now change color to blue 
   MessageBox(NULL, TEXT("Changing color to red"), TEXT(""), MB_OK); 
   VECTORVERTEX VertexTemp; 
   nRet = VectorVertex.LockObject(&VertexTemp); 
   if(nRet != SUCCESS) 
      return nRet; 
   VertexTemp.Pen.bExtPen = FALSE; 
   VertexTemp.Pen.NewPen.LogPen.lopnColor = RGB(255,0,0); 
   nRet = VectorVertex.UnlockObject(&VertexTemp); 
   if(nRet != SUCCESS) 
      return nRet; 
   //LVectorVertex destructor called when VectorVertex goes out of scope 
   return SUCCESS; 
}
