java.lang.Object
squidpony.squidgrid.gui.gdx.FloatFilter
squidpony.squidgrid.gui.gdx.FloatFilters.PaletteFilter
Enclosing class:
FloatFilters
public static class FloatFilters.PaletteFilter
extends FloatFilter
A FloatFilter that limits the colors it can return to a fixed palette, and won't return any colors that are missing from that palette (although it can always return fully-transparent). FloatFilters.PaletteReducerFilter is also an option; it uses more memory but is faster to look up colors in larger palettes (it has a maximum size of 256 colors, though, which this class doesn't).
