\class QColormap
\ingroup painting
\inmodule QtWidgets
\brief The QColormap class maps device independent QColors to device
dependent pixel values.
*/
/*! \enum QColormap::Mode
This enum describes how QColormap maps device independent RGB
values to device dependent pixel values.
\value Direct Pixel values are derived directly from the RGB
values, also known as "True Color."
\value Indexed Pixel values represent indexes into a list of
available colors, i.e. QColormap uses the index of the color that
most closely matches an RGB value.
\value Gray Similar to \c Indexed, pixel values represent a list
of available gray tones. QColormap uses the index of the gray
tone that most closely matches the computed gray tone of an RGB
value.
*/
/*!
\fn QColormap QColormap::instance(int screen)
Returns the colormap for the specified \a screen. If \a screen is
-1, this function returns the colormap for the default screen.
*/
/*!
\fn QColormap::QColormap(const QColormap &colormap)
Constructs a copy of another \a colormap.
*/
/*!
\fn QColormap::~QColormap()
Destroys the colormap.
*/
/*!
\fn int QColormap::size() const
Returns the size of the colormap for \c Indexed and \c Gray modes;
Returns -1 for \c Direct mode.
\sa colormap()
*/
/*!
\fn uint QColormap::pixel(const QColor &color) const
Returns a device dependent pixel value for the \a color.
\sa colorAt()
*/
/*!
\fn int QColormap::depth() const
Returns the depth of the device.
\sa size()
*/
/*!
\fn QColormap::Mode QColormap::mode() const
Returns the mode of this colormap.

*/
/*!
\fn const QColor QColormap::colorAt(uint pixel) const
Returns a QColor for the \a pixel.

\fn const QList<QColor> QColormap::colormap() const
Returns a list of colors which represents the devices colormap
for \c Indexed and \c Gray modes. This function returns an empty
list for \c Direct mode.

\fn QColormap &QColormap::operator=(const QColormap &colormap)
Assigns the given \a colormap to \e this color map and returns
