---|---|---|
figure | Figure | 要添加的图。 |
例子
此示例使用 GraphicsPath 和 Graphics 类在图像表面上创建和操作图形。示例在 GraphicsPath 类的帮助下创建一个新图像(Tiff 类型),清除表面并绘制路径。最后调用 Graphics 类公开的 DrawPath 方法来渲染表面上的路径。
[C#]
//创建一个FileStream实例
using (System.IO.FileStream stream = new System.IO.FileStream(@"C:\temp\output.tiff", System.IO.FileMode.Create))
{
//创建一个TiffOptions实例并设置它的各种属性
Aspose.Imaging.ImageOptions.TiffOptions tiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
//设置ImageOptions实例的来源
tiffOptions.Source = new Aspose.Imaging.Sources.StreamSource(stream);
//创建一个Image实例
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(tiffOptions, 500, 500))
{
//创建并初始化一个Graphics类的实例
Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(image);
//清除图形表面
graphics.Clear(Color.Wheat);
//创建GraphicsPath类的实例
Aspose.Imaging.GraphicsPath graphicspath = new Aspose.Imaging.GraphicsPath();
//创建一个Figure类的实例
Aspose.Imaging.Figure figure = new Aspose.Imaging.Figure();
//将形状添加到图形对象
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));
//将Figure对象添加到GraphicsPath
graphicspath.AddFigure(figure);
//使用颜色为黑色的 Pen 对象绘制路径
graphics.DrawPath(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Black, 2), graphicspath);
// 保存所有更改。
image.Save();
}
}
