Esempi

L’esempio seguente applica vari tipi di filtri a un’immagine WEBP.

[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;

    // Applica un filtro mediano con una dimensione del rettangolo di 5 all'intera immagine.
    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;

    // Applica un filtro levigante bilaterale con una dimensione del kernel di 5 all'intera immagine.
    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;

    // Applica un filtro sfocatura gaussiana con un raggio di 5 e un valore sigma di 4,0 all'intera immagine.
    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;

    // Applica un filtro Gauss-Wiener con un raggio di 5 e un valore uniforme di 4,0 all'intera immagine.
    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;

    // Applica un filtro motion wiener con una lunghezza di 5, un valore uniforme di 4,0 e un angolo di 90,0 gradi all'intera immagine.
    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;

    // Applica un filtro di nitidezza con una dimensione del kernel di 5 e un valore sigma di 4.0 all'intera immagine.
    webpImage.Filter(webpImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.SharpenFilterOptions(5, 4.0));
    webpImage.Save(dir + "sample.SharpenFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
