Image.RotateFlip

Image.RotateFlip method

旋转、翻转或同时旋转和翻转图像。

public abstract void RotateFlip(RotateFlipType rotateFlipType)
参数类型描述
rotateFlipTypeRotateFlipType旋转翻转的类型。

示例

此示例演示在图像上使用 Rotate 操作。示例从某个磁盘位置加载现有图像文件，并根据枚举 Aspose.Imaging.RotateFlipType 的值对图像执行旋转操作。

[C#]

//创建 image 类的实例，并通过文件路径使用现有图像文件进行初始化
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@"C:\temp\sample.bmp"))
{
    //将图像绕 X 轴旋转 180 度
    image.RotateFlip(Aspose.Imaging.RotateFlipType.Rotate180FlipX);

    // 保存所有更改。
    image.Save();
}

此示例加载图像，将其顺时针旋转90度，并可选地水平和（或）垂直翻转图像。

[C#]

string dir = "c:\\temp\\";

Aspose.Imaging.RotateFlipType[] rotateFlipTypes = new Aspose.Imaging.RotateFlipType[]
{
    Aspose.Imaging.RotateFlipType.Rotate90FlipNone,
    Aspose.Imaging.RotateFlipType.Rotate90FlipX,
    Aspose.Imaging.RotateFlipType.Rotate90FlipXY,
    Aspose.Imaging.RotateFlipType.Rotate90FlipY,
};

foreach (Aspose.Imaging.RotateFlipType rotateFlipType in rotateFlipTypes)
{
    // 旋转、翻转并保存到输出文件。
    using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.bmp"))
    {
        image.RotateFlip(rotateFlipType);
        image.Save(dir + "sample." + rotateFlipType + ".bmp");
    }
}

此示例加载 ODG 图像，将其顺时针旋转 90 度，并可选择水平和（或）垂直翻转图像。

[C#]

string dir = "c:\\temp\\";

Aspose.Imaging.RotateFlipType[] rotateFlipTypes = new Aspose.Imaging.RotateFlipType[]
{
    Aspose.Imaging.RotateFlipType.Rotate90FlipNone,
    Aspose.Imaging.RotateFlipType.Rotate90FlipX,
    Aspose.Imaging.RotateFlipType.Rotate90FlipXY,
    Aspose.Imaging.RotateFlipType.Rotate90FlipY,
};

foreach (Aspose.Imaging.Image rotateFlipType in rotateFlipTypes)
{
    // 旋转、翻转并保存到输出文件。
    using (Aspose.Imaging.Image image = (Aspose.Imaging.FileFormats.OpenDocument.OdImage)Aspose.Imaging.Image.Load(dir + "sample.odg"))
    {
        image.RotateFlip(rotateFlipType);
        image.Save(dir + "sample." + rotateFlipType + ".png", new Aspose.Imaging.ImageOptions.PngOptions());
    }
}
