(1)图片从文件导入

　　BitmapImage image = new BitmapImage();

　　image.BeginInit();

　　image.UriSource = new Uri(filename);

　　image.EndInit();

　　(2)图片从Binary导入

　　//已知Binary binary

　　MemoryStream ms = new MemoryStream(binary.ToArray());

　　BitmapImage image = new BitmapImage();

　　image.BeginInit();

　　image.StreamSource = ms;

　　image.EndInit();

　　(3)保存图片文件

　　//已知BitmapImage image

　　JpegBitmapEncoder encoder = new JpegBitmapEncoder();

　　encoder.Frames.Add(BitmapFrame.Create(image));

　　FileStream fileStream = new FileStream(imageFileName, FileMode.Create, FileAccess.ReadWrite);

　　encoder.Save(fileStream);

　　fileStream.Close();

　　(4)图片应用到材质

　　//已知BitmapImage image

　　ImageBrush imageBrush = new ImageBrush(image);

　　DiffuseMaterial material = new DiffuseMaterial();

　　material.Brush = imageBrush;
