Examples

The following example applies various types of filters to a WEBP image.

[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.webp"))
{
    Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;

    // Apply a median filter with a rectangle size of 5 to the entire image.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MedianFilterOptions(5));
    webpImage.Save(dir + "sample.MedianFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.webp"))
{
    Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;

    // Apply a bilateral smoothing filter with a kernel size of 5 to the entire image.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.BilateralSmoothingFilterOptions(5));
    webpImage.Save(dir + "sample.BilateralSmoothingFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.webp"))
{
    Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;

    // Apply a Gaussian blur filter with a radius of 5 and a sigma value of 4.0 to the entire image.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.GaussianBlurFilterOptions(5, 4.0));
    webpImage.Save(dir + "sample.GaussianBlurFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.webp"))
{
    Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;

    // Apply a Gauss-Wiener filter with a radius of 5 and a smooth value of 4.0 to the entire image.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.GaussWienerFilterOptions(5, 4.0));
    webpImage.Save(dir + "sample.GaussWienerFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.webp"))
{
    Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;

    // Apply a motion wiener filter with a length of 5, a smooth value of 4.0 and an angle of 90.0 degrees to the entire image.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MotionWienerFilterOptions(10, 1.0, 90.0));
    webpImage.Save(dir + "sample.MotionWienerFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.webp"))
{
    Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;

    // Apply a sharpen filter with a kernel size of 5 and a sigma value of 4.0 to the entire image.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.SharpenFilterOptions(5, 4.0));
    webpImage.Save(dir + "sample.SharpenFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
