Examples

This example creates a new Image and draws a variety of shapes using Figures and GraphicsPath on the Image surface

[C#]

//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.PolygonShape(new[] { new Aspose.Imaging.PointF(150, 10), new Aspose.Imaging.PointF(150, 200), new Aspose.Imaging.PointF(250, 300), new Aspose.Imaging.PointF(350, 400) }, true));
    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);

    // save all changes.
    image.Save();
}
