Adds a new vector object to a class object's group.
This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
#include "ltwrappr.h"
virtual L_INT LVectorGroup::AddObject(pVectorObject)
Pointer to an LVectorObject object that references the vector object to add.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
To use this function, declare an object from one of the classes derived from LVectorObject and pass the address of this object as the first parameter. The classes derived from LVectorObject are:
This example will add a new red line to the first Group in an LVectorBase object.
