    IColorPalette customPalette)

ditheringMethod	DitheringMethod	The dithering method.
bitsCount	Int32	The final bits count for dithering.
customPalette	IColorPalette	The custom palette for dithering.

Examples

The following example loads a DJVU image and performs threshold and floyd dithering using different palette depth.

[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.djvu"))
{
    Aspose.Imaging.FileFormats.Djvu.DjvuImage dicomImage = (Aspose.Imaging.FileFormats.Djvu.DjvuImage)image;

    // Perform threshold dithering using 4-bit color palette which contains 16 colors.
    // The more bits specified the higher quality and the bigger size of the output image.
    // Note that only 1-bit, 4-bit and 8-bit palettes are supported at the moment.
    dicomImage.Dither(Aspose.Imaging.DitheringMethod.ThresholdDithering, 4, null);

    dicomImage.Save(dir + "sample.ThresholdDithering4.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.djvu"))
{
    Aspose.Imaging.FileFormats.Djvu.DjvuImage dicomImage = (Aspose.Imaging.FileFormats.Djvu.DjvuImage)image;

    // Perform floyd dithering using 1-bit color palette which contains only 2 colors - black and white.
    // The more bits specified the higher quality and the bigger size of the output image.
    // Note that only 1-bit, 4-bit and 8-bit palettes are supported at the moment.
    dicomImage.Dither(Aspose.Imaging.DitheringMethod.FloydSteinbergDithering, 1, null);

    dicomImage.Save(dir + "sample.FloydSteinbergDithering1.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
