+A palette is a table that maps pixel values to RGB colours. It allows the
+colours of a low-depth bitmap, for example, to be mapped to the available
+colours in a display. The notion of palettes is becoming more and more
+obsolete nowadays and only the MSW port is still using a native palette.
+All other ports use generic code which is basically just an array of
+colours.
+
+It is likely that in the future the only use for palettes within wxWidgets
+will be for representing colour indeces from images (such as GIF or PNG).
+The image handlers for these formats have been modified to create a palette
+if there is such information in the original image file (usually 256 or less
+colour images). See \helpref{wxImage}{wximage} for more information.

\func{}{wxPalette}{\param{const wxPalette\&}{ palette}}
-Copy constructor. This uses reference counting so is a cheap operation.
+Copy constructor, uses \helpref{reference counting}{trefcount}.

Returns a pixel value (index into the palette) for the given RGB values.
\wxheading{Return value}
-The nearest palette index.
+The nearest palette index or {\tt wxNOT\_FOUND} for unexpected errors.

\perlnote{In wxPerl this method takes only the {\tt pixel} parameter and
returns a 3-element list ( or the empty list upon failure ).}
-\membersection{wxPalette::Ok}\label{wxpaletteok}
+\membersection{wxPalette::IsOk}\label{wxpaletteisok}
-\constfunc{bool}{Ok}{\void}
+\constfunc{bool}{IsOk}{\void}
Returns true if palette data is present.
\func{wxPalette\&}{operator $=$}{\param{const wxPalette\& }{palette}}
-Assignment operator, using reference counting. Returns a reference
-to `this'.
-
-\membersection{wxPalette::operator $==$}\label{wxpaletteequals}
-
-\func{bool}{operator $==$}{\param{const wxPalette\& }{palette}}
-
-Equality operator. Two palettes are equal if they contain pointers
-to the same underlying palette data. It does not compare each attribute,
-so two independently-created palettes using the same parameters will
-fail the test.
-
-\membersection{wxPalette::operator $!=$}\label{wxpalettenotequals}
-
-\func{bool}{operator $!=$}{\param{const wxPalette\& }{palette}}
-
-Inequality operator. Two palettes are not equal if they contain pointers
-to different underlying palette data. It does not compare each attribute.
-
+Assignment operator, using \helpref{reference counting}{trefcount}.
