LVectorBase::AddObject

Summary

Adds a new vector object to the class object's active vector layer.

This function is available in the LEADTOOLS Vector Imaging Toolkit.

Syntax

#include "ltwrappr.h"

virtual L_INT LVectorBase::AddObject(pVectorObject);

Parameters

LVectorObject * pVectorObject

Pointer to an LVectorObject object that references the vector object to add.

Returns

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

Required DLLs and Libraries

Example

This example will add a new green vertex to the Active Layer LVectorBase object.
Once added, the color will be changed to blue.
