Consistent Colors
|

|
|
Since XMPP can be used on multiple platforms at the same time,
|
||
|
|
it might be a good idea to render given Strings like nicknames in the same
|
||
|
|
color on all platforms to provide a consistent user experience.
|
||
|
|
|
||
|
|
The utility class `ConsistentColor` allows the generation of colors to a given
|
||
|
|
string following the specification of [XEP-0392](https://xmpp.org/extensions/xep-0392.html).
|
||
|
|
|
||
|
|
##Usage
|
||
|
|
To generate a consistent color for a given string, call
|
||
|
|
```
|
||
|
|
float[] rgb = ConsistentColor.RGBFrom(input);
|
||
|
|
```
|
||
|
|
The resulting float array contains values for RGB in the range of 0 to 1.
|
||
|
|
|
||
|
|
##Color Deficiency Corrections
|
||
|
|
Some users might suffer from color vision deficiencies. To compensate those deficiencies,
|
||
|
|
the API allows for color correction. The color correction mode is a static value, which can be changed at any time.
|
||
|
|
|
||
|
|
To correct colors for users with red-green color deficiency use the following code:
|
||
|
|
```
|
||
|
|
ConsistentColor.activateRedGreenBlindnessCorrection();
|
||
|
|
```
|
||
|
|
|
||
|
|
For color correction for users with blue-blindness, call
|
||
|
|
```
|
||
|
|
ConsistentColor.activateBlueBlindnessCorrection();
|
||
|
|
```
|
||
|
|
|
||
|
|
To deactivate color vision deficiency correction, call
|
||
|
|
```
|
||
|
|
ConsistenColor.deactivateDeficiencyCorrection();
|
||
|
|
```
