Examples
Dessa exempel använder GraphicsPath och Graphics klass för att skapa och manipulera Figurer på en bild yta. Exempel skapar en ny bild (typ Tiff), rengör ytan och drar vägar med hjälp av GraphicsPath klass.

}Constructors
Figure()
Initialiserar en ny Aspose.Imaging.Figur instans.En konstruktor som krävs för en JSON deserialisering.
public Figure()Properties
Bounds
Får eller sätter objektets gränser.
public override RectangleF Bounds { get; }Fastighetsvärde
IsClosed
får eller ställer in ett värde som anger om denna siffra är stängd.En stängd siffra gör en skillnad endast omformerna i den första och sista figuren är kontinuerliga former. i så fall kommer den första punkten i den första formen att varaansluten av en raka linje från sista punkten i den sista formen.
