如何使用 Aspose.Imaging 为 .NET 创建艺术和风格效应

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

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

using (Image image = Image.Load(inputPath))
{
    var rect = new Aspose.Imaging.Rectangle(0, 0, image.Width, image.Height);
    image.Filter(rect, new GrayscaleFilterOptions()); // Step 1: Grayscale
    // Apply sepia tone by adjusting color channels
    using (RasterImage raster = image as RasterImage)
    {
        for (int y = 0; y < raster.Height; y++)
        {
            for (int x = 0; x < raster.Width; x++)
            {
                var color = raster.GetPixel(x, y);
                int tr = (int)(color.R * 0.393 + color.G * 0.769 + color.B * 0.189);
                int tg = (int)(color.R * 0.349 + color.G * 0.686 + color.B * 0.168);
                int tb = (int)(color.R * 0.272 + color.G * 0.534 + color.B * 0.131);
                raster.SetPixel(x, y, Color.FromArgb(
                    Math.Min(tr, 255),
                    Math.Min(tg, 255),
                    Math.Min(tb, 255)));
            }
        }
    }
    image.Save(outputPath, new PngOptions());
}

image.Filter(rect, new EmbossFilterOptions());
image.Filter(rect, new GaussWienerFilterOptions(4, 4));
