示例
此示例使用 Graphics 类在图像表面创建基本形状。为了演示操作，示例创建一个新的 PNG 格式图像，并使用 Graphics 类提供的 Draw 方法在图像表面绘制基本形状。```csharp [C#]
//创建 FileStream 的实例
using (System.IO.FileStream stream = new System.IO.FileStream(@"C:\temp\output.png", System.IO.FileMode.Create))
{
//创建 PngOptions 的实例并设置其各种属性
Aspose.Imaging.ImageOptions.PngOptions pngOptions = new Aspose.Imaging.ImageOptions.PngOptions();
//为 PngOptions 设置源
pngOptions.Source = new Aspose.Imaging.Sources.StreamSource(stream);
//创建图像的实例
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(pngOptions, 500, 500))
{
//创建并初始化 Graphics 类的实例
Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(image);
//清除 Graphics 表面
graphics.Clear(Aspose.Imaging.Color.Wheat);
//通过指定具有黑色的 Pen 对象、围绕弧的矩形、起始角度和扫掠角度绘制弧
graphics.DrawArc(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Black, 2), new Aspose.Imaging.Rectangle(200, 200, 100, 200), 0, 300);
//通过指定具有蓝色的 Pen 对象和坐标点绘制贝塞尔曲线
graphics.DrawBezier(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Blue, 2), new Aspose.Imaging.Point(250, 100), new Aspose.Imaging.Point(300, 30), new Aspose.Imaging.Point(450, 100), new Aspose.Imaging.Point(235, 25));
//通过指定具有绿色的 Pen 对象和点数组绘制曲线
graphics.DrawCurve(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Green, 2), new[] { new Aspose.Imaging.Point(100, 200), new Aspose.Imaging.Point(100, 350), new Aspose.Imaging.Point(200, 450) });
//使用 Pen 对象和围绕的矩形绘制椭圆
graphics.DrawEllipse(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Yellow, 2), new Aspose.Imaging.Rectangle(300, 300, 100, 100));
//绘制一条直线
graphics.DrawLine(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Violet, 2), new Aspose.Imaging.Point(100, 100), new Aspose.Imaging.Point(200, 200));
//绘制一个扇形
graphics.DrawPie(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Silver, 2), new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(200, 20), new Aspose.Imaging.Size(200, 200)), 0, 45);
//通过指定具有红色的 Pen 对象和点数组绘制多边形
graphics.DrawPolygon(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Red, 2), new[] { new Aspose.Imaging.Point(20, 100), new Aspose.Imaging.Point(20, 200), new Aspose.Imaging.Point(220, 20) });
//绘制矩形
graphics.DrawRectangle(new Aspose.Imaging.Pen(Aspose.Imaging.Color.Orange, 2), new Aspose.Imaging.Rectangle(new Aspose.Imaging.Point(250, 250), new Aspose.Imaging.Size(100, 100)));
//创建 SolidBrush 对象并设置其各种属性
Aspose.Imaging.Brushes.SolidBrush brush = new Aspose.Imaging.Brushes.SolidBrush();
brush.Color = Color.Purple;
brush.Opacity = 100;
//使用 SolidBrush 对象和字体在特定点绘制字符串
graphics.DrawString("此图像是由 Aspose.Imaging API 创建的", new Aspose.Imaging.Font("Times New Roman", 16), brush, new Aspose.Imaging.PointF(50, 400));
//保存所有更改。
image.Save();
}
}
