Properties

Optional blackWhiteClamp

blackWhiteClamp?: {
    channel: Ref;
    max: number;
    min: number;
}

Used to configure SDR black and clamping. channel indicates the space.channel to use for determining when to clamp. min indicates the lower limit for black clamping and max indicates the upper limit for white clamping

Type declaration

  • channel: Ref
  • max: number
  • min: number

Optional deltaEMethod

deltaEMethod?: "" | "76" | "Jz" | "HCT" | "CMC" | "2000" | "ITP" | "OK" | "OK2"

Optional jnd

jnd?: number

The "just noticeable difference" to target

Optional method

method?: "css" | "clip" | string & {}

How to force into gamut.

If "clip", coordinates are just clipped to their reference range.
If "css", coordinates are reduced according to the CSS 4 Gamut Mapping Algorithm.
If in the form [colorSpaceId].[coordName], that coordinate is reduced until the color is in gamut. Please note that this may produce nonsensical results for certain coordinates (e.g. hue) or infinite loops if reducing the coordinate never brings the color in gamut

Default

"css"

Optional space

space?: string | Space

The color whose space is being mapped to. Defaults to the current space
