Enhance the current image by applying dithering effects with this straightforward method. Perfect for developers aiming to add texture and depth to images, improving their visual quality and overall appeal.

public override void Dither(DitheringMethod ditheringMethod, int bitsCount, 
    IColorPalette customPalette)
ParameterTypeDescription
ditheringMethodDitheringMethodThe dithering method.
bitsCountInt32The final bits count for dithering.
customPaletteIColorPaletteThe custom palette for dithering.

Examples

The following example loads a DICOM 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.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)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.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)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());
}
