When using the Text-IO library, you can configure the text terminals via properties files. Colors can be specified using standard HTML names (e.g. orange, chocolate, crimson), hex strings (e.g. #ee5533, #e53, 0xEE5533), rgb format strings (e.g. rgb(217,33,119), rgba(112,25%,50%,0.9)), or hsl format strings (e.g. hsl(240,90%,70%), hsla(270,0%,100%,0.7)).

How does Text-IO create colors from these string representations? Until recently, the implementation used the static method web(String colorString) provided by javafx.scene.Color. This method supports all the above mentioned formats and returns a javafx.scene.Color instance. Text-IO needs a java.awt.Color, but creating one from the returned javafx.scene.Color is straightforward.

However, I was not happy with this solution. It made my code depend on JavaFX, although Text-IO doesn’t actually use JavaFX. And, starting with JDK 11, JavaFX is no longer part of the JDK.

So, I decided to write a little library named AWT Color Factory for creating java.awt.Color  objects from string representations. The simplest way to do this is to copy the code of the javafx.scene.Color.web(String colorString) method and adapt it to create  java.awt.Colorinstances.

But, what about licensing? JavaFX is released under the GPL, so my library must use the same license. Text-IO is, instead, released under the Apache-2.0 license. Is it then allowed to use my library? Yes, it is. The license under which JavaFX iwas released is actually not GPL but the GPL 2 with Classpath exception. The same applies to my library. This is very important, because the Classpath exception clause gives you permission to include the AWT Color Factory library in your executable code, regardless of the license under which your software is distributed.

Example Usage

Color c1 = ColorFactory.valueOf("firebrick");
Color c2 = ColorFactory.valueOf("#aa38e0");
Color c3 = ColorFactory.valueOf("0x40A8CC");
Color c4 = ColorFactory.valueOf("rgba(112,36,228,0.9)");
Color c5 = ColorFactory.web("forestgreen", 0.7);
Color c6 = ColorFactory.web("hsl(270,90%,70%)", 0.8);


AWT Color Factory is available in JCenter and Maven Central.

Maven

<dependency>
    <groupId>org.beryx</groupId>
    <artifactId>awt-color-factory</artifactId>
    <version>1.0.0</version>
</dependency>


Gradle

compile 'org.beryx:awt-color-factory:1.0.0'


The library requires Java 7 or newer. The jar artifact is modularized under the name org.beryx.awt.color.

Starting with version 3.2.0, Text-IO uses the AWT Color Factory library and no longer depends on JavaFX.
