GifImage.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)

Parameter	Type	Description
rectangle	Rectangle	The rectangle.
options	FilterOptionsBase	The 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());
}

    // 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());

    // 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());
