FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package color-compare

ColorCompare

License: MIT Build Status

ColorCompare is a library to convert colors from hex, RGB, HSL, CIE L*a*b* (LAB) and DIN-99 into one another and calculate color distances (human visual difference) using the DIN-99 methedology.

You can get the library from packagist:

How to use

You can get the DIN-99 visual difference (distance) of two colors easily:

You can convert each format into one another:

You can create the color object by Hex, RGB, HSL and LAB:

Visual Color Distance with DIN-99

DIN-99 differences, returned by Color::getDifference(), can better calculate the human visual difference than LAB with delta-E. There are also superior distance calculations like CIE94 or CIEDE2000 but these are complicated and need intensive calculations. With DIN-99 the calculation is done beforehand and needs less ressources. When your color is already converted into DIN-99 you can just calculate the euklidean distance and get the same quality.

This is a huge advantage! If you would like, per example, make a client side filter of colored products (or whatever) you can convert your data into DIN-99 on the server side and only need to do the easier euklidean calculation in your JavaScript.
