Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	FloatFilters.ChainFilter	A FloatFilter that chains together one or more FloatFilters one after the next, passing the float output of one as input to the next until the chain has all been called.
static class	FloatFilters.ColorizeFilter	Changes all colors this alters to have the same hue as, and a closer saturation to, a target color given in the constructor, as well as optionally multiplying saturation of the result and/or adding lightness/value.
static class	FloatFilters.DistinctRedGreenFilter	A FloatFilter that alters primarily-red and primarily-green colors so they can be more easily be distinguished by people with at least some forms of red-green color-blindness (deuteranopia should be handled well, protanopia very well, and tritanopia may not benefit at all).
static class	FloatFilters.GrayscaleFilter	A FloatFilter that makes all colors given to it grayscale, using only their luma as calculated by SColor.lumaOfFloat(float) as the lightness (it does also preserve alpha transparency).
static class	FloatFilters.HSVFilter	Wraps the functionality of SColor.toEditedFloat(float, float, float, float, float) so it can be called as a FloatFilter, adding values to hue, saturation, and value (clamping saturation and value and wrapping hue).
static class	FloatFilters.IdentityFilter	A FloatFilter that makes no changes to the colors given to it; useful as a default for when no filter is wanted.
static class	FloatFilters.LerpFilter	A FloatFilter that linearly interpolates (lerps) any color it is given toward a specified color by a specified amount.
static class	FloatFilters.MultiLerpFilter	A FloatFilter that linearly interpolates (lerps) any color it is given toward the most-similar of a group of given colors.
static class	FloatFilters.PaletteFilter	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).
static class	FloatFilters.PaletteReducerFilter	A FloatFilter that limits the colors it can return to a fixed palette as determined by a PaletteReducer, and won't return any colors that are missing from that palette (although it can always return fully-transparent).
static class	FloatFilters.YCbCrFilter	Like FloatFilters.HSVFilter, but edits its input colors in YCbCr color space, and multiplies rather than adds.
static class	FloatFilters.YCoCgFilter	Like FloatFilters.YCbCrFilter, but edits its input colors in YCoCg color space, or like FloatFilters.HSVFilter except it doesn't add, it multiplies.
static class	FloatFilters.YCwCmFilter	Like FloatFilters.YCbCrFilter or FloatFilters.YCoCgFilter, but edits its input colors in YCwCm color space, which is very similar to YCoCg but has chroma/chrominance components that are useful aesthetically on their own.

identityFilter

public static final FloatFilters.IdentityFilter identityFilter

A static constant of the one possible IdentityFilter, to avoid needing to make duplicates. IdentityFilter makes no changes to the colors given to it.

grayscaleFilter
