如何将 Blur、Sharpen 和 Grayscale 过滤器应用到图像

using System;
using Aspose.Imaging;
using Aspose.Imaging.FileFormats.Png;
using Aspose.Imaging.ImageOptions;
using Aspose.Imaging.Filters;

string inputPath = @"./photo.jpg";
string outputPath = @"./photo_blur.png";

using (Image image = Image.Load(inputPath))
{
    // Define the region for filtering (entire image)
    var rect = new Aspose.Imaging.Rectangle(0, 0, image.Width, image.Height);
    // Apply a blur filter (GaussWiener)
    image.Filter(rect, new GaussWienerFilterOptions(7, 7));
    // Save the processed image
    image.Save(outputPath, new PngOptions());
}

// Sharpen
image.Filter(rect, new SharpenFilterOptions(5));
// Grayscale
image.Filter(rect, new GrayscaleFilterOptions());

string[] files = Directory.GetFiles("./batch", "*.jpg");
foreach (var file in files)
{
    using (Image img = Image.Load(file))
    {
        img.Filter(new Aspose.Imaging.Rectangle(0, 0, img.Width, img.Height), new GaussWienerFilterOptions(5, 5));
        img.Save(Path.ChangeExtension(file, ".blurred.png"), new PngOptions());
    }
}
