MedianCutQuantizer (PlantUML 1.2023.0 API)

java.lang.Object
- net.sourceforge.plantuml.quantization.MedianCutQuantizer

All Implemented Interfaces:

ColorQuantizer
```
public final class MedianCutQuantizer
extends Object
implements ColorQuantizer
```
Implements median cut quantization.
The algorithm works as follows:
- Begin with one cluster containing all the original colors.
- Find the cluster containing the greatest spread along a single color component (red, green or blue).
- Find the median of that color component among colors in the cluster.
- Split the cluster into two halves, using that median as a threshold.
- Repeat this process until the desired number of clusters is reached.

    Description copied from interface: ColorQuantizer
    
    Quantize the given set of colors, returning a set no larger than maxColors.
    The intent is to pick a set of colors which are representative of the original color set, but no specific guarantees are made.

    originalColors - the colors in the original image
    
    maxColorCount - the maximum number of colors to allow
    
    Returns:
    
    a quantized collection of colors no larger than maxColors
