LVectorBase::DeleteObject

#include "ltwrappr.h"

virtual L_INT LVectorBase::DeleteObject(dwFlags=0)

Deletes objects from a vector image.

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

Parameters

L_UINT32 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

Value Meaning
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.
