#include "ltwrappr.h"

virtual L_INT LVectorBase::DeleteObject(dwFlags=0)

L_UINT32 dwFlags;

flag that indicates which objects to delete

Deletes objects from a vector image.

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

Parameter Description
dwFlags Flag that indicates which objects to delete. Possible values are:
  Value Meaning
  0 Delete all objects.
  VECTOR_FLAGS_SELECTED_ONLY Delete only the currently selected objects within the vector handle.

Returns

SUCCESS

Comments7

Deletes all or part of the vector image.

Note: When you delete a certain object, it may or may not effect other unselected objects sharing vertices with the selected object. This depends on the current bind vertices mode set by LVectorBase::SetBindVerticesMode.

Note: In DirectX, you cannot delete objects, therefore this function does nothing.

L_INT LVectorBase__DeleteObjectExample(HWND hWnd, LVectorBase *pVector) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
   UNREFERENCED_PARAMETER(pVector); 
   L_INT       nRet; 
   LVectorBase Vector; 
   nRet = Vector.Load(MAKE_IMAGE_PATH(TEXT("random.dxf"))); 
   if(nRet != SUCCESS) 
      return nRet; 
   nRet = Vector.DeleteObject(); 
   if(nRet != SUCCESS) 
      return nRet;
