Examples
Ces exemples utilisent la classe GraphicsPath et les graphiques pour créer et manipuler les Figures sur une surface d’image. Exemple crée une nouvelle image (de type Tiff), nettoie la surface et attire les chemins à l’aide de la classes GraphiquePate.
//Create an instance of FileStream
using (System.IO.FileStream stream = new System.IO.FileStream(@"C:\temp\output.tiff", System.IO.FileMode.Create))

//Create an instance of TiffOptions and set its various properties

//Set the source for the instance of ImageOptions
tiffOptions.Source = new Aspose.Imaging.Sources.StreamSource(stream);
//Create an instance of Image
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(tiffOptions, 500, 500))
{
//Create and initialize an instance of Graphics class
Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(image);
//Clear Graphics surface
graphics.Clear(Color.Wheat);
//Create an instance of GraphicsPath class
Aspose.Imaging.GraphicsPath graphicspath = new Aspose.Imaging.GraphicsPath();
//Create an instance of Figure class
Aspose.Imaging.Figure figure = new Aspose.Imaging.Figure();
//Add Shapes to Figure object
figure.AddShape(new Aspose.Imaging.Shapes.RectangleShape(new Aspose.Imaging.RectangleF(10f, 10f, 300f, 300f)));
figure.AddShape(new Aspose.Imaging.Shapes.EllipseShape(new Aspose.Imaging.RectangleF(50f, 50f, 300f, 300f)));
