/**
Purpose: ease using and converting HTML and SVG color names taking advantage of the
public class W3C_Colors class methods
Generated by: parse_and_create_w3c_colors.rex
Usage 1: require 'w3c_colors.cls' and use its public class .W3C_Colors with the following class methods
.W3C_Colors~getColorNameFromHex(someHexValue) ... returns mixed case name or .nil, if hex unknown
someHexValue either "#rrggbb" or "#rgb"
.W3C_Colors~getColorNameFromRGB(someRgbValue) ... returns mixed case name or .nil, if rgb unknown
someRgbValue either "rgb(r,g,b)"
.W3C_Colors~getColorNameFromRGB(r, g, b) ... returns mixed case name or .nil, if rgb unknown
r, g, b ... decimal value between 0 and 255 for red, green blue
.W3C_Colors~getMixedCaseName(someColorName) ... returns mixed case name or .nil, if name unknown
.W3C_Colors~getHexValue(someColorName) ... returns "#rrggbb" or .nil, if name unknown
.W3C_Colors~getRgbValue(someColorName) ... returns "rgb(r,g,b)" or .nil, if name unknown
.W3C_Colors~isSvgColorName(someColorName) ... returns .true if name is a SVG name,
.false if name is not a SVG name ("RebeccaPurple")
or .nil, if name unknown
Usage 2: invoke as a command supplying no, one or two arguments
@param colorname one of the W3C defined color names
@param distance optional from colorName, distance a real number between 0 and 1, or a %

/** Defines the usage information for this Rexx pacakge. */
::resource usage
w3c_colors.cls ... utility for dealing with W3C colors
usage 1 (requires directive in a program):
::requires "w3c_colors.cls"
... requires "sRGB.cls" and as a result makes the public class W3C_Colors with its class
methods available, as well as the DeltaEOK method of the sRGB class and other conversion
methods, for example sRGB to linear RGB, XYZ and OKLab.
usage 2: rexx w3c_colors.cls [color percent]
... with no argument the .W3C_Colors' class methods get demonstrated
... with exactly two arguments, 'color percentOrDistance' the method DeltaEOK() of the sRGB class
gets demonstrated, where color could be a w3c color name, hex, or rgb, e.g.
rexx w3c_colors.cls thistle 16
