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

Aspose.Imaging.ImageResizeSettings resizeSettings = new Aspose.Imaging.ImageResizeSettings();

// The adaptive algorithm based on weighted and blended rational function and lanczos3 interpolation.
resizeSettings.Mode = Aspose.Imaging.ResizeType.AdaptiveResample;

// The small rectangular filter
resizeSettings.FilterType = Aspose.Imaging.ImageFilterType.SmallRectangular;

// The number of colors in the palette.
resizeSettings.EntriesCount = 256;

// The color quantization is not used
resizeSettings.ColorQuantizationMethod = ColorQuantizationMethod.None;

// The euclidian method
resizeSettings.ColorCompareMethod = ColorCompareMethod.Euclidian;

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.gif"))
{
    // Scale down by 2 times using adaptive resampling.
    image.Resize(image.Width / 2, image.Height / 2, resizeSettings);
    image.Save(dir + "downsample.adaptive.gif");
