Examples
Questo esempio crea una nuova Immagine e attira una varietà di forme utilizzando Figure e GraphicsPath sulla superficie dell’Imagine
//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();

Examples
Questi esempi utilizzano la classe GraphicsPath e la grafica per creare e manipolare le figure su una superficie dell’immagine. Esempio crea una nuova Immagine (di tipo Tiff), pulisce la superficie e traccia i percorsi con l’aiuto della classe Grafica.
//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
Aspose.Imaging.ImageOptions.TiffOptions tiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
//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)));
figure.AddShape(new Aspose.Imaging.Shapes.PieShape(new Aspose.Imaging.RectangleF(new Aspose.Imaging.PointF(250f, 250f), new Aspose.Imaging.SizeF(200f, 200f)), 0f, 45f));
//Add Figure object to GraphicsPath
graphicspath.AddFigure(figure);
//Draw path with Pen object of color Black
graphics.DrawPath(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Black, 2), graphicspath);
// save all changes.
image.Save();
