Color4
######
.. code-block::
#include <Imath/ImathColor.h>
The ``Color4`` class template represents a 4-component color (red,
green, blue, and alpha), with pre-defined typedefs of ``unsigned
char``, ``half``, and ``float``.
The ``Color4`` class is *not* derived from ``Vec4``. Its fields are
named ``r``, ``g``, ``b``, and ``a``. The class itself implies no
specific interpretation of the values.
There are also various utility functions that operate on colors
defined in ``ImathColorAlgo.h`` and described in :ref:`Color Functions
<color-functions>`.
Example:
.. literalinclude:: ../examples/Color4.cpp
:language: c++
.. doxygentypedef:: Color4c
.. doxygentypedef:: Color4h
.. doxygentypedef:: Color4f
.. doxygentypedef:: C4c
.. doxygentypedef:: C4h
.. doxygentypedef:: C4f
.. doxygenclass:: Imath::Color4
:undoc-members:
:members:
.. doxygenfunction:: operator<<(std::ostream& s, const Color4<T>& v)
