Color helper library for converting between RGB, CMYK, HSV, HST and HEX and create interpolation.
color conversions and transitions (e.g. interpolation).
Developed by ARTACK WebLab GmbH in Zurich, Switzerland.
- Provides class representation for RGB, CMYK, HSV, HSL and HEX.
- Provides conversion between all class representation
- Provides transitions between colors (e.g. interpolation)
- Provides clear exceptions to be able to handle library exceptions
- Compatible with PHP >= 7.
You can install ARTACK's color library through Composer:
$ composer require artack/color
Creating a RGB class representation:
$RGB = new RGB(0, 255, 0); echo $RGB->getGreen(); // 255
Translate RGR class representation to HSV:
$converter = Factory::createConverter(); $RGB = new RGB(0, 255, 0); $HSV = $converter->convert($RGB, HSV::class);
Get an interpolation color between two colors with the value (and max) given:
$transition = Factory::createTransition(); $RGBRed = new RGB(255, 0, 0); // red $RGBGreen = new RGB(0, 255, 0); // green $RGBInterpolated = $transition->interpolate(RGB::class, $RGBRed, $RGBGreen, 100, 200); // should be ~yellow // Interpolation will give better results when using HSV Transition. Colors get converted automaticly if needed. $HSVInterpolated = $transition->interpolate(HSV::class, $RGBRed, $RGBGreen, 100, 200); // should be ~yellow
