PaletteSerialization

java.lang.Object
- net.sourceforge.jiu.color.io.PaletteSerialization

All Implemented Interfaces:

RGBIndex
```
public class PaletteSerialization
extends Object
implements RGBIndex
```
This class loads and saves palettes. Loading is done using the ImageLoader class - an image is loaded which is supposed to have no more than 256 pixels, the palette entries. When saving, the PNMCodec is used to store palettes as .ppm files.

Since:

0.5.0
