DrawPath

Graphics.DrawPath method

Draws a GraphicsPath.

public void DrawPath(Pen pen, GraphicsPath path)
Parameter Type Description
pen Pen Pen that determines the color, width, and style of the path.
path GraphicsPath GraphicsPath to draw.

Exceptions

exception condition
ArgumentNullException pen is null. -or- path is null.

Examples

This examples make use of GraphicsPath and Graphics class to create and manipulate Figures on an Image surface. Example creates a new Image (of type Tiff), clears the surface and draws paths with the help of GraphicsPath class. At the end DrawPath method exposed by Graphics class is called to render the paths on surface.

//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))

        //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();
