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.
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 argument. The classes derived from LVectorObject are:
LVectorHPolyBezier
Required DLLs and Libraries
This example will add a new red line to the Active Layer LVectorBase object.
