A color model convert an image sample value to a color.
All images do not store necesarly rgb values, there can be a indexed color palette
or any other kind of computation to obtain a color.
The color model takes care to convert sample to color and color to sample.

Variables : -
Functions : getColorSpace, toColor, toColorARGB, toSample, toSample, asTupleBuffer


Colorspace provided by the tuple buffer method.
return  ColorSpace, never null.
ColorSpace getColorSpace ()


Convert given sample in a color.
param  sample
return  ColorRGBA
Color toColor (Object sample)


Convert given sample in a ARGB integer color.
8bits per color components : A R G B
param  sample
return  ARGB color as integer
int toColorARGB (Object sample)


Convert given color in a sample value.
Caution 1 : there might exist multiple sample values for a color
There is no guarantee on which sample value will be choosen
Caution 2 : given color might not have an exact match in this color model
The color model will choose arbitrarly a close value.
param  color
return  Object most appropriate sample structure
Object toSample (Color color)


Convert given color in a sample value.
Caution 1 : there might exist multiple sample values for a color
There is no guarantee on which sample value will be choosen
Caution 2 : given color might not have an exact match in this color model
The color model will choose arbitrarly a close value.
param  color
return  Object most appropriate sample structure
Object toSample (int color)


Provide a tuple buffer view as a one sample int tuple.
The PixelBuffer provide additional accessors for color types.
param  image
return  PixelBuffer
PixelBuffer asTupleBuffer (Image image)
