What's this? a finished project from Mikee? Surely not.

 

I made a little library for messing with colors.

 

http://code.google.com/p/colorjizz/

 

(Badly) ported to 4 languages at the moment.

 

Struggling with my unit tests though. There will always be slight conversion differences, so I'm not sure if I should leave my unit tests to fail or specific a range of error to let them pass. But who decides the range of error? :/

 

For example, if I convert to one format then back again, it might be 0.0004 out when it converts back. Obviously makes no difference in reality, but hmm.

Upgraded, using PHP namespaces now using PSR-2. Added to Jenkins with unit testing and code coverage, also moved it over to Github and added it to packagist.

What does it do?

It's for playing with colours.

You can convert colours from one format to any of the other formats, for example:

<?php
echo Hex::create(0xCC0000)->toCMYK();
echo Hex::create(0xCC0000)->toCIELab();
echo Hex::create(0xCC0000)->toCIELCh();
echo Hex::create(0xCC0000)->toRGB();
echo Hex::fromString('black')->toHSV();
echo RGB::create(200,100,150)->toHex();
?>

Or find colour harmonies, modify colours or match colours:

<?php
echo Hex::fromString('#cc0000')->greyscale();

echo Hex::fromString('#cc0000')->websafe();

echo Hex::fromString('#cc0000')->match(array(
  new RGB(0,0,0),
  new XYZ(1,1,1),
  new Hex(0x00FF00)
));

echo Hex::create(0xFF0000)->range(Hex::create(0x0000FF), 100);

echo new RGB(100,0,100)->split(2);

echo new RGB(100,0,100)->hue(-2);
?>

I should document it properly at some point with examples.

(no syntax highlighting? :()

Edit: oh, I kinda have a bit. https://github.com/mikeemoo/ColorJizz-PHP/

So did he.

Uhrmm... :/
