}ArcShape(RectangleF, float, float, bool)
Initialisiert eine neue Instanz der Aspose.Imaging.Shapes.ArcShape Klasse.
public ArcShape(RectangleF rectangle, float startAngle, float sweepAngle, bool isClosed)Parameters
rectangle RectangleF
Die rechte Ecke.
startAngle float
Der Anfangsang.
sweepAngle float
Der schmutzige Winkel.
isClosed bool
Wenn die “Glauben” festgelegt wird, wird der Arc geschlossen. Der geschlossene Arc degeneriert tatsächlich zu einer Ellipse.
Properties
EndPoint
Erreicht das Endformpunkt.
[JsonIgnore]
public PointF EndPoint { get; }Eigentumswert
IsClosed
Er bekommt oder setzt einen Wert, der angibt, ob die bestellte Form geschlossen ist. Bei der Verarbeitung geschlossen die bestellte Form haben die Anfangs- und Endpunkte keinen Sinn.
[JsonProperty]
public bool IsClosed { get; set; }Eigentumswert
Segments
Sie erhalten die Formsegmente.
[JsonIgnore]
public override ShapeSegment[] Segments { get; }Eigentumswert
ShapeSegment [][]
StartPoint
Erhalten Sie den Anfangsformpunkt.
[JsonIgnore]
public PointF StartPoint { get; }Eigentumswert
