以下示例显示了如何设置 WMF 的背景颜色。实际上它在绘制所有其他对象之前绘制了一个背景颜色的矩形。

[C#]

string dir = "c:\\aspose.imaging\\issues\\net\\3280\\";
string inputFilePath = dir + "image2.wmf";
string outputFilePath = dir + "ChangeBackground_" + "image2.wmf";

using (Aspose.Imaging.FileFormats.Emf.MetaImage image = (Aspose.Imaging.FileFormats.Emf.MetaImage)Aspose.Imaging.Image.Load(inputFilePath))
{
    AddBackgroundRectangleWmf((Aspose.Imaging.FileFormats.Wmf.WmfImage)image, Aspose.Imaging.Color.Blue);
    image.Save(outputFilePath);
}

/// <summary>
/// 改变 WMF 背景的辅助方法。 
/// </summary>
public static void AddBackgroundRectangleWmf(Aspose.Imaging.FileFormats.Wmf.WmfImage image, Aspose.Imaging.Color color)
{
    image.CacheData();
    if (image.Records.Count < 1)
    {
        return;
    }

    //设置矩形
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfRectangle rectangle = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfRectangle();
    rectangle.Rectangle = image.FrameBounds;

    //设置画笔
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfCreateBrushInDirect brush = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfCreateBrushInDirect();
    brush.LogBrush = new Aspose.Imaging.FileFormats.Emf.Emf.Objects.EmfLogBrushEx();
    brush.LogBrush.Argb32ColorRef = color.ToArgb();

    //选择画笔
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfSelectObject selectObject = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfSelectObject(brush);

    //删除画笔
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfDeleteObject deleteObject = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfDeleteObject(brush);

    //添加记录
    image.Records.Insert(0, brush);
    image.Records.Insert(1, selectObject);
    image.Records.Insert(2, rectangle);
    image.Records.Insert(3, deleteObject);
}
