+ \class QColormap
+ \ingroup multimedia
+
+ \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 vector 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 vector
+ 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.

+ \fn uint QColormap::pixel(const QColor &color) const
