KGy SOFT Drawing Libraries Help
Gets an OrderedDitherer using a 8x8 matrix of a dotted halftone pattern.
See the Examples section for some examples.

Assembly:  KGySoft.Drawing (in KGySoft.Drawing.dll) Version: 5.2.1

public static OrderedDitherer DottedHalftone { get; }

Property Value

Type: OrderedDitherer

The following example demonstrates how to use the ditherer returned by this property:
public static Bitmap ToDitheredDottedHalftone(Bitmap source, IQuantizer quantizer)
    IDitherer ditherer = OrderedDitherer.DottedHalftone;

    // a.) this solution returns a new bitmap and does not change the original one:
    return source.ConvertPixelFormat(quantizer.PixelFormatHint, quantizer, ditherer);

    // b.) alternatively, you can perform the dithering directly on the source bitmap:
    source.Dither(quantizer, ditherer);
    return source;

The example above may produce the following results:
