README

Getting started:

ColorJizz-PHP uses the PSR-0 standards for namespaces, so there should be no trouble using with frameworks like Symfony 2.

Autoloading

An autoloader class is provided for when loading ColorJizz yourself.

First, include the autoloader and call the static register() function.

<?php
require_once 'path/to/colorjizz/lib/MischiefCollective/ColorJizz/Autoloader.php';
MischiefCollective\ColorJizz\Autoloader::register();
?>

Now all ColorJizz classes will be automatically loaded in.

Converting between formats

ColorJizz can convert to and from any of the supported color formats:

<?php
use MischiefCollective\ColorJizz\Formats\Hex;

$red_hex = new Hex(0xFF0000);
$red_cmyk = $hex->toCMYK();

echo get_class($red_cmyk); // MischiefCollective\ColorJizz\Formats\CMYK
echo $red_cmyk; // 0,1,1,0
?>

Any color manipulation or conversion will return a new instance of a color class, therefore your original color objects remains intact.

Color manipulation can be chained together:

<?php
use MischiefCollective\ColorJizz\Formats\Hex;

echo Hex::fromString('red')->hue(-20)->greyscale(); // 555555
?>

Any color manipulation will always return the color in the same format unless you're specifically converting the format. For example:

<?php
use MischiefCollective\ColorJizz\Formats\RGB;

$red = new RGB(255, 0, 0);
echo get_class($red->hue(-20)->saturation(2)); // MischiefCollective\ColorJizz\Formats\RGB
?>

Supported formats:

<?php
new RGB(r, g, b);
new CMY(c, m, y);
new CMYK(c, m, y, k);
new Hex(0x000000);
new HSV(h, s, v);
new CIELab(l, a, b);
new CIELCh(l, c, h);
new XYZ(x, y, z);
new Yxy(Y, x, y);

Conversion functions:

<?php
->toRGB();
->toCMY();
->toCMYK();
->toHex();
->toHSV();
->toCIELab();
->toCIELCh();
->toXYZ();
->toYxy();
