/**
|
|
* CSS color parser compliant with CSS Color 4 Specification.
|
|
* Supports: named colors, `transparent` keyword, all rgb hex notations,
|
|
* rgb(), rgba(), hsl() and hsla() functions.
|
|
* Does not round the parsed values to integers from the range 0..255.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* <alpha-value> = <number> | <percentage>
|
|
* <hue> = <number> | <angle>
|
|
*
|
|
* rgb() = rgb( <percentage>{3} [ / <alpha-value> ]? ) | rgb( <number>{3} [ / <alpha-value> ]? )
|
|
* rgb() = rgb( <percentage>#{3} , <alpha-value>? ) | rgb( <number>#{3} , <alpha-value>? )
|
|
*
|
|
* hsl() = hsl( <hue> <percentage> <percentage> [ / <alpha-value> ]? )
|
|
* hsl() = hsl( <hue>, <percentage>, <percentage>, <alpha-value>? )
|
|
*
|
|
* Caveats:
|
|
* - <angle> - <number> with optional `deg` suffix; `grad`, `rad`, `turn` are not supported
|
|
* - `none` keyword is not supported
|
|
* - comments inside rgb()/hsl() are not supported
|
|
* - legacy color syntax rgba() is supported with an identical grammar and behavior to rgb()
|
|
* - legacy color syntax hsla() is supported with an identical grammar and behavior to hsl()
|
|
*
|
|
* @param input CSS color string to parse.
|
|
* @returns Color in sRGB color space, with `red`, `green`, `blue`
|
|
* and `alpha` channels normalized to the range 0..1,
|
|
* or `undefined` if the input is not a valid color string.

/**
|
|
* Returns a ratio that can be used to interpolate between exponential function
|
|
* stops.
|
|
* How it works: Two consecutive stop values define a (scaled and shifted) exponential function `f(x) = a * base^x + b`, where `base` is the user-specified base,
|
|
* and `a` and `b` are constants affording sufficient degrees of freedom to fit
|
|
* the function to the given stops.
|
|
*
|
|
* Here's a bit of algebra that lets us compute `f(x)` directly from the stop
|
|
* values without explicitly solving for `a` and `b`:
|
|
*
|
|
* First stop value: `f(x0) = y0 = a * base^x0 + b`
|
|
* Second stop value: `f(x1) = y1 = a * base^x1 + b`
|
|
* => `y1 - y0 = a(base^x1 - base^x0)`
|
|
* => `a = (y1 - y0)/(base^x1 - base^x0)`
|
|
*
|
|
* Desired value: `f(x) = y = a * base^x + b`
|
|
* => `f(x) = y0 + a * (base^x - base^x0)`
|
|
*
|
|
* From the above, we can replace the `a` in `a * (base^x - base^x0)` and do a
|
|
* little algebra:
|
|
* ```
|
|
* a * (base^x - base^x0) = (y1 - y0)/(base^x1 - base^x0) * (base^x - base^x0)
|
|
* = (y1 - y0) * (base^x - base^x0) / (base^x1 - base^x0)
|
|
* ```
|
|
*
|
|
* If we let `(base^x - base^x0) / (base^x1 base^x0)`, then we have
|
|
* `f(x) = y0 + (y1 - y0) * ratio`. In other words, `ratio` may be treated as
|
|
* an interpolation factor between the two stops' output values.
|
|
*
|
|
* (Note: a slightly different form for `ratio`,
|
|
* `(base^(x-x0) - 1) / (base^(x1-x0) - 1) `, is equivalent, but requires fewer
|
|
* expensive `Math.pow()` operations.)
