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

Modifier and Type	Method and Description
IFunction	duplicate()
double	eval() Returns each ARGB value packed in an int that is casted to double.
void	findCursors(Collection<Cursor<?>> cursors) Put any cursors in use by this function (and any nested functions) in @param cursors.

RGBA

public RGBA(IFunction fn,
            int channel)
     throws IllegalArgumentException

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.

Throws:

Exception - If the channel < 1 or > 4.

IllegalArgumentException
