Examples
Questi esempi utilizzano la classe GraphicsPath e la grafica per creare e manipolare le figure su una superficie dell’immagine. Esempio crea una nuova Immagine (di tipo Tiff), pulisce la superficie e traccia i percorsi con l’aiuto della classe Grafica.

}Constructors
Figure()
Inizia una nuova instanza Aspose.Imaging.Figura.Un costruttore richiesto per una deserializzazione JSON.
public Figure()Properties
Bounds
Riceve o mette i confini dell’oggetto.
public override RectangleF Bounds { get; }Valore di proprietà
IsClosed
Riceve o impone un valore che indica se questa cifra è chiusa. Una cifra chiusa farà una differenza solo sele forme della prima e dell’ultima figura sono forme continuo; in questo caso il primo punto della prima forma saràcollegato da una linea retta dall’ultimo punto dell’ultima forma.
public bool IsClosed { get; set; }Valore di proprietà
Segments
Riceve l’intero segmento della figura.
public ShapeSegment[] Segments { get; }Valore di proprietà
ShapeSegment [ ]
Shapes
Riceve le forme.
[JsonProperty]
public Shape[] Shapes { get; }Valore di proprietà
Shape [ ]
Methods
