Summary

Deletes objects from a vector image.

This function is available in the LEADTOOLS Vector Imaging Toolkit.

Syntax

virtual L_INT LVectorBase::DeleteObject(dwFlags=0)

Parameters

L_UINT32 dwFlags

Flag that indicates which objects to delete. Possible values are:

Returns

Comments

Deletes all or part of the vector image.

Notes:

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

Required DLLs and Libraries

• LTVKRN
• For a listing of the exact DLLs and Libraries needed, based on the toolkit version, refer to Files To Be Included With Your Application.

   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)
