Examples
This example creates a new Image and draws a variety of shapes using Figures and GraphicsPath on the Image surface
//Creates an instance of BmpOptions and set its various properties
Aspose.Imaging.ImageOptions.BmpOptions bmpOptions = new Aspose.Imaging.ImageOptions.BmpOptions();
bmpOptions.BitsPerPixel = 24;
//Create an instance of FileCreateSource and assign it as Source for the instance of BmpOptions
//Second Boolean parameter determines if the file to be created IsTemporal or not
bmpOptions.Source = new Aspose.Imaging.Sources.FileCreateSource(@"c:\temp\output.bmp", false);
//Create an instance of Image
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(bmpOptions, 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 figure1 = new Aspose.Imaging.Figure();
//Add Shape to Figure object
figure1.AddShape(new Aspose.Imaging.Shapes.EllipseShape(new RectangleF(50, 50, 300, 300)));
figure1.AddShape(new Aspose.Imaging.Shapes.PieShape(new Rectangle(new Point(110, 110), new Size(200, 200)), 0, 90));
//Create an instance of Figure class
Aspose.Imaging.Figure figure2 = new Aspose.Imaging.Figure();
//Add Shape to Figure object
figure2.AddShape(new Aspose.Imaging.Shapes.ArcShape(new Aspose.Imaging.RectangleF(10, 10, 300, 300), 0, 45));

figure2.AddShape(new Aspose.Imaging.Shapes.RectangleShape(new Aspose.Imaging.RectangleF(new Aspose.Imaging.Point(250, 250), new Aspose.Imaging.Size(200, 200))));
//Add Figure object to GraphicsPath
graphicspath.AddFigures(new[] { figure1, figure2 });
//Draw path with Pen object of color Black
graphics.DrawPath(new Pen(Aspose.Imaging.Color.Black, 2), graphicspath);
