例子

以下示例将各种类型的过滤器应用于光栅图像。

[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 对整个图像应用一个矩形大小为 5 的中值滤波器。
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MedianFilterOptions(5));
    rasterImage.Save(dir + "sample.MedianFilter.png");
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 对整个图像应用内核大小为 5 的双边平滑滤波器。
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.BilateralSmoothingFilterOptions(5));
    rasterImage.Save(dir + "sample.BilateralSmoothingFilter.png");
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 对整个图像应用半径为 5、sigma 值为 4.0 的高斯模糊滤镜。
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.GaussianBlurFilterOptions(5, 4.0));
    rasterImage.Save(dir + "sample.GaussianBlurFilter.png");
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 对整个图像应用半径为 5、平滑值为 4.0 的 Gauss-Wiener 滤波器。
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.GaussWienerFilterOptions(5, 4.0));
    rasterImage.Save(dir + "sample.GaussWienerFilter.png");
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 对整个图像应用长度为 5、平滑值为 4.0、角度为 90.0 度的运动维纳滤波器。
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MotionWienerFilterOptions(10, 1.0, 90.0));
    rasterImage.Save(dir + "sample.MotionWienerFilter.png");
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 对整个图像应用内核大小为 5、sigma 值为 4.0 的锐化过滤器。
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.SharpenFilterOptions(5, 4.0));
    rasterImage.Save(dir + "sample.SharpenFilter.png");
}
