}这个例子创造了一个新的图像,并在图像表面上使用图像和图形Path引导各种形状。
//Creates an instance of BmpOptions and set its various properties
Aspose.Imaging.ImageOptions.BmpOptions bmpOptions = new Aspose.Imaging.ImageOptions.BmpOptions();
bmpOptions.BitsPerPixel = 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.Source = new Aspose.Imaging.Sources.FileCreateSource(@"c:\temp\output.bmp", false);
//Create an instance of Image
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(bmpOptions, 500, 500))
{
//Create and initialize an instance of Graphics class

//Clear Graphics surface

//Add Shape to Figure object
figure1.AddShape(new Aspose.Imaging.Shapes.EllipseShape(new RectangleF(50, 50, 300, 300)));
figure1.AddShape(new Aspose.Imaging.Shapes.PieShape(new Rectangle(new Point(110, 110), new Size(200, 200)), 0, 90));
