LVectorBase::DeleteObject

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

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.

Example

This example deletes all objects in a vector.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName
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;
   return SUCCESS;
