如何使用 Aspose.Imaging 为 .NET 重新编辑 Web 和 移动图像

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

string inputPath = @"./photo.jpg";
string outputPath = @"./photo_resized.jpg";

using (Image image = Image.Load(inputPath))
{
    image.Resize(800, 600, ResizeType.LanczosResample); // Resize to 800x600 (for web)
    image.Save(outputPath, new JpegOptions());
}

int targetWidth = 480; // e.g., mobile width
using (Image image = Image.Load(inputPath))
{
    double aspectRatio = (double)image.Height / image.Width;
    int targetHeight = (int)(targetWidth * aspectRatio);
    image.Resize(targetWidth, targetHeight, ResizeType.LanczosResample);
    image.Save("./photo_mobile.jpg", new JpegOptions());
}

string inputDir = @"./input";
string outputDir = @"./output";
Directory.CreateDirectory(outputDir);
string[] files = Directory.GetFiles(inputDir, "*.jpg");
foreach (var file in files)
{
    using (Image img = Image.Load(file))
    {
        img.Resize(1024, 768, ResizeType.LanczosResample);
        string outPath = Path.Combine(outputDir, Path.GetFileName(file));
        img.Save(outPath, new JpegOptions());
    }
}

var options = new JpegOptions { Quality = 85 }; // Tune for web
using (Image image = Image.Load(inputPath))
{
    image.Resize(800, 600, ResizeType.LanczosResample);
    image.Save("./photo_web.jpg", options);
}
