Dithering Filter
Intro
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.
UI
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.
