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.PointF(250, 250),
                        new com.aspose.imaging.SizeF(200, 200)),
                        0, 45));

        // Add Figure object to GraphicsPath

        // 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();
