Filter

GifImage.Filter method

Apply a specific filter to the designated area of the image, enhancing its visual quality or altering its appearance as desired. This method selectively processes pixels within the defined rectangle, allowing for targeted adjustments to be made while preserving the integrity of the surrounding image data.

public override void Filter(Rectangle rectangle, FilterOptionsBase options)
ParameterTypeDescription
rectangleRectangleThe rectangle.
optionsFilterOptionsBaseThe options.

Examples

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

[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    Aspose.Imaging.FileFormats.Gif.GifImage gifImage = (Aspose.Imaging.FileFormats.Gif.GifImage)image;

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    Aspose.Imaging.FileFormats.Gif.GifImage gifImage = (Aspose.Imaging.FileFormats.Gif.GifImage)image;

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    Aspose.Imaging.FileFormats.Gif.GifImage gifImage = (Aspose.Imaging.FileFormats.Gif.GifImage)image;

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    Aspose.Imaging.FileFormats.Gif.GifImage gifImage = (Aspose.Imaging.FileFormats.Gif.GifImage)image;

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    Aspose.Imaging.FileFormats.Gif.GifImage gifImage = (Aspose.Imaging.FileFormats.Gif.GifImage)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.
    gifImage.Filter(gifImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MotionWienerFilterOptions(10, 1.0, 90.0));
    gifImage.Save(dir + "sample.MotionWienerFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    Aspose.Imaging.FileFormats.Gif.GifImage gifImage = (Aspose.Imaging.FileFormats.Gif.GifImage)image;

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