LVectorLayer::AddObject

#include "ltwrappr.h"

virtual L_INT LVectorBase::AddObject(pVectorObject);

Adds a new vector object to the class object's layer. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

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.

Example

This example will add a new red line to the Active Layer LVectorBase object.
