Posterization
Posterization
Section titled “Posterization” Category Effects
Is Pair Node: No
Applies a posterization effect to the input background painter, reducing the number of colors in the image.
Posterization Mode
Section titled “Posterization Mode”In RGB mode, the posterization effect is applied to each of the red, green and blue channels separately. The levels input determines how many distinct values each channel can have. For example, if the levels input is set to 4, each channel can only have 4 distinct values (0, 85, 170, 255), resulting in a total of 64 possible colors (4 for red * 4 for green * 4 for blue).
Luminance
Section titled “Luminance”In Luminance mode, the posterization effect is applied to the luminance of the image. The levels input determines how many distinct luminance values the image can have. The colors in the output image are determined by mapping the original colors to the nearest color with the corresponding luminance level.
Color Space Type
Section titled “Color Space Type”Inherit
Section titled “Inherit”The posterization effect will be applied in the same color space as the render context (usually the document’s color space).
The posterization effect will be applied in the sRGB color space, which is a standard color space for images that are displayed on screens.
Linear sRGB
Section titled “Linear sRGB”The posterization effect will be applied in the linear sRGB color space, which is a linearized version of the sRGB color space. This can result in a different visual effect compared to applying the posterization in the standard sRGB color space, especially when working with colors that have a wide range of luminance values.
Inputs
Section titled “Inputs” Background
Section titled “ Background ” Type: Painter
Default: unset
The background painter to which the posterization effect will be applied.
Type: Posterization Mode
Default: Rgb
The mode of posterization to apply.
Levels
Section titled “ Levels ” Type: Integer
Default: 8
The number of color levels to use in the posterization effect. Higher values will result in a less pronounced effect, while lower values will create a more stylized, abstract look.
Color Space
Section titled “ Color Space ” Type: Color Space Type
Default: sRGB
The color space in which the posterization effect will be applied.
Outputs
Section titled “Outputs” Output
Section titled “ Output ” Type: Painter
Default: unset
The resulting painter with the posterization effect applied.
