Convert HEX or RGB values into decimal rgb color values, compatible with Corona and Defold format

Lua Color Converter

Convert HEX or RGB values into decimal rgb color values, compatible with Corona and Defold format, (numbers from 0 to 1).

How To Install:

1. Put lua-color-converter.lua into your project directory

2. Load it in your scripts when neccesary:

local color = require("lua-color-converter")

3. Use it to convert from hex:

color.hex("ff00ff") -- 0.5, 0, 0.5

-- You can include "#" in your string if needed

color.hex("#ff00ff") -- 0.5, 0, 0.5

.. and to convert from regular byte rgb:

-- r,g,b
color.rgb(255, 0, 255) -- 0.5, 0, 0.5

You can use one more argument to set alpha channel:

color.hex("ff00ff", 0.5) --alpha set to 50%
color.rgb(255, 0, 255, 75) --alpha set to 75%

Examples:

local myText = display.newText( "example from Corona Docs", 0, 0, native.systemFontBold, 12 )
myText:setFillColor( color.hex("#ff10ae") )

go.set("#label", "color", vmath.vector4(color.rgb(255, 16, 174, 1))
