Adds a new vector object to the class object's active vector layer.
This function is available in the LEADTOOLS Vector Imaging Toolkit.
#include "ltwrappr.h"
virtual L_INT LVectorBase::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. |
This example will add a new green vertex to the Active Layer LVectorBase object.
Once added, the color will be changed to blue.
