例子

这个例子展示了 Pen 对象的创建和使用。该示例创建一个新图像并在图像表面上绘制矩形。

[C#]

//创建一个BmpOptions的实例并设置它的各种属性
Aspose.Imaging.ImageOptions.BmpOptions bmpOptions = new Aspose.Imaging.ImageOptions.BmpOptions();
bmpOptions.BitsPerPixel = 24;

//创建一个 FileCreateSource 的实例并将其分配为 BmpOptions 实例的 Source
//第二个布尔参数确定要创建的文件是否为IsTemporal
bmpOptions.Source = new Aspose.Imaging.Sources.FileCreateSource(@"C:\temp\sample.bmp", false);

//在指定路径创建一个Image实例
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(bmpOptions, 500, 500))
{
    //创建一个Graphics实例并用Image对象初始化
    Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(image);

    //用白色清除图形表面
    graphics.Clear(Aspose.Imaging.Color.White);

    //创建一个Pen实例，颜色为红色，宽度为5
    Aspose.Imaging.Pen pen = new Aspose.Imaging.Pen(Aspose.Imaging.Color.Red, 5f);

    //创建一个HatchBrush实例并设置它的属性
    Aspose.Imaging.Brushes.HatchBrush brush = new Aspose.Imaging.Brushes.HatchBrush();
    brush.BackgroundColor = Aspose.Imaging.Color.Wheat;
    brush.ForegroundColor = Aspose.Imaging.Color.Red;

    //创建一个Pen实例
    //用 HatchBrush 对象和宽度初始化它
    Aspose.Imaging.Pen brusedpen = new Pen(brush, 5);

    //通过指定Pen对象绘制矩形
    graphics.DrawRectangles(pen, new[]
    {
        new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(210, 210), new Aspose.Imaging.Size(100, 100)),
        new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(110, 110), new Aspose.Imaging.Size(100, 100)),
        new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(310, 310), new Aspose.Imaging.Size(100, 100))
    });

    //通过指定Pen对象绘制矩形
    graphics.DrawRectangles(brusedpen, new[]
    {
        new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(310, 110), new Aspose.Imaging.Size(100, 100)),
        new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(110, 310), new Aspose.Imaging.Size(100, 100))
    });

    // 保存所有更改。
    image.Save();
}
