[Valid for](../../../../Shared/FeatureAvailability.md): CANoe DE • CANoe4SW DE

## Function Syntax

```plaintext theme={null}
long Iso11783IL_OPChangePolygonPoint( dword polygonID, dword index, dword x, dword y ); // form 1
long Iso11783IL_OPChangePolygonPoint( dbNode implement, dword polygonID, dword index, dword x, dword y ); // form 2
```
