Code example:

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
com.aspose.imaging.imageoptions.BmpOptions bmpOptions = new com.aspose.imaging.imageoptions.BmpOptions();
bmpOptions.setBitsPerPixel(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.setSource(new com.aspose.imaging.sources.FileCreateSource("c:\\temp\\output.bmp", false));

//Create an instance of Image
com.aspose.imaging.Image image = com.aspose.imaging.Image.create(bmpOptions, 500, 500);
try {
    //Create and initialize an instance of Graphics class
    com.aspose.imaging.Graphics graphics = new com.aspose.imaging.Graphics(image);

    //Clear Graphics surface

    figure2.addShape(new com.aspose.imaging.shapes.RectangleShape(
            new com.aspose.imaging.RectangleF(
                    new com.aspose.imaging.PointF(250, 250),
                    new com.aspose.imaging.SizeF(200, 200))));

    //Add Figure object to GraphicsPath
    graphicspath.addFigures(new com.aspose.imaging.Figure[]{figure1, figure2});

    //Draw path with Pen object of color Black
    graphics.drawPath(new com.aspose.imaging.Pen(com.aspose.imaging.Color.getBlack(), 2), graphicspath);

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

Constructor Detail

PieShape

public PieShape()

Initializes a new instance of the PieShape class.

PieShape

public PieShape(RectangleF rectangle,
                float startAngle,
                float sweepAngle)

Initializes a new instance of the PieShape class.

Parameters:

rectangle - The rectangle.

startAngle - The start angle.

sweepAngle - The sweep angle.

Code example:

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) and draw 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
com.aspose.imaging.system.io.FileStream stream = new com.aspose.imaging.system.io.FileStream("C:\\temp\\output.tif", com.aspose.imaging.system.io.FileMode.Create);
try {
    // Create an instance of TiffOptions and set its various properties
    com.aspose.imaging.imageoptions.TiffOptions tiffOptions = new com.aspose.imaging.imageoptions.TiffOptions(com.aspose.imaging.fileformats.tiff.enums.TiffExpectedFormat.Default);

    // Set the source for the instance of ImageOptions
    tiffOptions.setSource(new com.aspose.imaging.sources.StreamSource(stream));

    // Create an instance of Image
    com.aspose.imaging.Image image = com.aspose.imaging.Image.create(tiffOptions, 500, 500);
    try {
        // Create and initialize an instance of Graphics class
        com.aspose.imaging.Graphics graphics = new com.aspose.imaging.Graphics(image);

        // Clear Graphics surface
        graphics.clear(com.aspose.imaging.Color.getWheat());

        // Create an instance of GraphicsPath class
        com.aspose.imaging.GraphicsPath graphicspath = new com.aspose.imaging.GraphicsPath();

        // Create an instance of Figure class
        com.aspose.imaging.Figure figure = new com.aspose.imaging.Figure();

        // Add Shapes to Figure object
        figure.addShape(new com.aspose.imaging.shapes.RectangleShape(new com.aspose.imaging.RectangleF(10, 10, 300, 300)));
        figure.addShape(new com.aspose.imaging.shapes.EllipseShape(new com.aspose.imaging.RectangleF(50, 50, 300, 300)));
        figure.addShape(
                new com.aspose.imaging.shapes.PieShape(new com.aspose.imaging.RectangleF(
                        new com.aspose.imaging.PointF(250, 250),
                        new com.aspose.imaging.SizeF(200, 200)),
                        0, 45));

        // Add Figure object to GraphicsPath
        graphicspath.addFigure(figure);

        // Draw path with Pen object of color Black
        graphics.drawPath(new com.aspose.imaging.Pen(com.aspose.imaging.Color.getBlack(), 2), graphicspath);

        // Save all changes.
        image.save();
    } finally {
        image.dispose();
    }
} finally {
    stream.dispose();
}
