Ejemplos

El siguiente ejemplo aplica varios tipos de filtros a una imagen ráster.

[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;

    // Aplicar un filtro mediano con un tamaño de rectángulo de 5 a toda la imagen.
    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;

    // Aplicar un filtro de suavizado bilateral con un tamaño de kernel de 5 a toda la imagen.
    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;

    // Aplicar un filtro de desenfoque gaussiano con un radio de 5 y un valor sigma de 4,0 a toda la imagen.
    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;

    // Aplicar un filtro de Gauss-Wiener con un radio de 5 y un valor suave de 4,0 a toda la imagen.
    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;

    // Aplicar un filtro Wiener de movimiento con una longitud de 5, un valor suave de 4,0 y un ángulo de 90,0 grados a toda la imagen.
    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;

    // Aplicar un filtro de nitidez con un tamaño de núcleo de 5 y un valor sigma de 4,0 a toda la imagen.
    rasterImage.Filter(rasterImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.SharpenFilterOptions(5, 4.0));
    rasterImage.Save(dir + "sample.SharpenFilter.png");
}
