Interface HCLColorFactory

An HCL (CIELCH) color factory object, which may also be used with instanceof to test if an object is an HCL color instance.

interface HCLColorFactory {
    [metadata]: DecoratorMetadataObject;
    arguments: any;
    caller: Function;
    length: number;
    name: string;
    prototype: HCLColor;
    [hasInstance](value): boolean;
    apply(this, thisArg, argArray?): any;
    bind(this, thisArg, ...argArray): any;
    call(this, thisArg, ...argArray): any;
    toString(): string;
    (h, c, l, opacity?): HCLColor;
    (cssColorSpecifier): HCLColor;
    (color): HCLColor;
}

Hierarchy

  • HCLColorFactory(h, c, l, opacity?): HCLColor

  • Constructs a new HCL color based on the specified channel values and opacity.

    Parameters

    • h: number

      Hue channel value typically in [0, 360).

    • c: number

      Chroma channel value typically in [0, 230].

    • l: number

      Luminance channel value typically in the range [0, 100].

    • Optional opacity: number

      Optional opacity value, defaults to 1.

    Returns HCLColor

  • HCLColorFactory(cssColorSpecifier): HCLColor

  • Parses the specified CSS Color Module Level 3 specifier string, returning an HCL color. If the specifier was not valid, null is returned.

    Parameters

    • cssColorSpecifier: string

      A CSS Color Module Level 3 specifier string.

    Returns HCLColor

  • HCLColorFactory(color): HCLColor

  • Converts the provided color instance and returns an HCL color. The color instance is converted to the RGB color space using color.rgb and then converted to HCL. (Colors already in the HCL color space skip the conversion to RGB, and colors in the Lab color space are converted directly to HCL.)

    Parameters

    Returns HCLColor

Methods

[hasInstance]

  • [hasInstance](value): boolean

  • Determines whether the given value inherits from this function if this function was used as a constructor function.

    A constructor function can control which objects are recognized as its instances by 'instanceof' by overriding this method.

    Parameters

    • value: any

    Returns boolean

apply

  • apply(this, thisArg, argArray?): any

  • Calls the function, substituting the specified object for the this value of the function, and the specified array for the arguments of the function.

    Parameters

    • this: Function
    • thisArg: any

      The object to be used as the this object.

    • Optional argArray: any

      A set of arguments to be passed to the function.

    Returns any

bind

  • bind(this, thisArg, ...argArray): any

  • For a given function, creates a bound function that has the same body as the original function. The this object of the bound function is associated with the specified object, and has the specified initial parameters.

    Parameters

    • this: Function
    • thisArg: any

      An object to which the this keyword can refer inside the new function.

    • Rest ...argArray: any[]

      A list of arguments to be passed to the new function.

    Returns any

call

  • call(this, thisArg, ...argArray): any

  • Calls a method of an object, substituting another object for the current object.

    Parameters

    • this: Function
    • thisArg: any

      The object to be used as the current object.

    • Rest ...argArray: any[]

      A list of arguments to be passed to the method.

    Returns any

toString

  • toString(): string

  • Returns a string representation of a function.

    Returns string

Properties

caller: Function

Readonly length

length: number

Readonly name

name: string

Returns the name of the function. Function names are read-only and can not be changed.

Readonly prototype

prototype: HCLColor

Prototype of the factory, which can be used for instanceof testing
