DitheringMode Enumeration

The dithering algorithm for converting to bitonal images

Dithering is the process of converting continuous-tone (grayscale or color) content to black-and-white (bitonal) representation. Different algorithms offer trade-offs between visual quality and compression efficiency.

public enum DitheringMode

Members

Member name	Value	Description
None	0	No dithering Simple thresholding without dithering. Best for clean line art and text-only documents.
Halftone	1	Halftone dithering Ordered halftone dithering using a periodic pattern. Provides a good balance between visual quality and compression.
FloydSteinberg	2	Floyd-Steinberg dithering Error diffusion dithering that distributes quantization errors to neighboring pixels. Produces high-quality results, especially for photographic content.
Atkinson	3	Atkinson dithering A variant of error diffusion dithering that produces results with good compression characteristics.
