#include "ltwrappr.h"

virtual L_INT LVectorBase::EnumVerticesCallBack(pVector, pVertex)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
pVECTORPOINT pVertex;	/* pointer to a vector vertex */

Processes each vertex enumerated by the LVectorBase::EnumVertices function.

Parameter	Description
pVector	Pointer to the vector image containing the objects to enumerate.
pVertex	Pointer to the vector vertex being processed.

Returns

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

Comments

The LVectorBase::EnumVertices function calls your callback function as it gets the handle of each vector vertex.

To use this function, you must do the following:

1. Derive a class from LVectorBase.

2. Override the L_INT LVectorBase::EnumVerticesCallBack. Function in your class.

3. Before calling LVectorBase::EnumVertices, you must call the member function LBase::EnableCallBack(TRUE).
