如何在 .NET 中以 90、180 或 270 度旋转图像

using Aspose.Imaging;
using Aspose.Imaging.ImageOptions;

string inputPath = "./input/photo.jpg";
string output90 = "./output/photo_rotated_90.jpg";
string output180 = "./output/photo_rotated_180.jpg";
string output270 = "./output/photo_rotated_270.jpg";

using (var image = Image.Load(inputPath))
{
    image.RotateFlip(RotateFlipType.Rotate90FlipNone);
    image.Save(output90, new JpegOptions { Quality = 90 });
}
using (var image = Image.Load(inputPath))
{
    image.RotateFlip(RotateFlipType.Rotate180FlipNone);
    image.Save(output180, new JpegOptions { Quality = 90 });
}
using (var image = Image.Load(inputPath))
{
    image.RotateFlip(RotateFlipType.Rotate270FlipNone);
    image.Save(output270, new JpegOptions { Quality = 90 });
}
