Dithering Filter


Dithering is an image processing operation used to create the illusion of color depth in images with a limited color palette. Colors not available in the palette are approximated by a diffusion of colored pixels from within the available palette.

Mode - Select a dithering mode:

  • Blend - Generate half of the pattern using the color's bit depth.
  • Classic - Uses a dithering algorithm where colors are either 1 or 0.
  • Grayscale - The brightness of the image/Shape is used.

Greyscale Mode - Determine how the image/Shape is sampled. See Common Attributes.

Bit Depth - Determine the resulting bit depth.

Size - The size of the resulting dithered 'pixels'.

Pattern - Set the type of dithering pattern to apply:

  • Bayer - Produces a very distinctive cross-hatch pattern.
  • Bricks - Produces a brick like pattern.
  • Stripes - Produces a striped pattern.
  • Bubbles - Produces a bubble pattern.
  • Virus - Produces an abstract pattern.
  • Blue Noise - Produces a pattern based on blue noise.
  • White Noise - Produces a pattern based on noise.
  • Custom - Use a Shader to create a custom pattern.

Shader - Add/connect a custom Shader.

Contrast - Increase/decrease contrast to affect how gradually the pattern changes.

Bias - Adjust the dithering to affect darker or brighter areas of the Shape.
