Commenti

Se necessario, l'utente deve mantenere i punti originali. I punti originali vengono convertiti in punti di controllo bézier cubici internamente, pertanto non esiste alcun meccanismo per restituire i punti originali.

La curva inizia in corrispondenza del punto della matrice specificata da offsete include il numero di punti (segmenti) specificati da numberOfSegments.

Esempio

L'esempio di codice seguente è progettato per l'uso con Windows Forms e richiede PaintEventArgse, un OnPaint oggetto evento. Il codice esegue le azioni seguenti:

• Crea una matrice di quattro punti (che rappresenta una spline cardinale).

• Crea un percorso e usando la matrice di punti, aggiunge la curva al percorso.

• Disegna il percorso dello schermo.

Si noti che mentre la matrice contiene quattro punti, sono presenti solo tre segmenti, ovvero il numero specificato nel terzo argomento della chiamata a AddCurve.

La curva inizia in corrispondenza del punto della matrice specificata dal offset parametro e include il numero di punti (segmenti) specificati da numberOfSegments.
