Constructor Summary

Constructors
Constructor and Description
`RGBA(IFunction red, IFunction green, IFunction blue, IFunction alpha)`
`RGBA(IFunction fn, int channel)` Creates an RGBA with only the given channel filled, from 1 to 4, where RGBA is really ARGB and thus A=4, R=3, G=2, B=1.
`RGBA(Image<? extends RealType<?>> img)` Interpret the @param img as an ARGB image.
`RGBA(Object red)` Accepts only `Image`, `Number`, `IFunction` instances or null as arguments.
`RGBA(Object ob, int channel)` Creates an RGBA with only the given channel filled, from 1 to 4, where RGBA is really ARGB and thus A=4, R=3, G=2, B=1.
`RGBA(Object red, Object green)` Accepts only `Image`, `Number`, `IFunction` instances or null as arguments.
`RGBA(Object red, Object green, Object blue)` Accepts only `Image`, `Number`, `IFunction` instances or null as arguments.
`RGBA(Object red, Object green, Object blue, Object alpha)` Accepts only `Image`, `Number`, `IFunction` instances or null as arguments.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
