Duplicate a palette data using imPaletteNew. * \ingroup palette
Searches for the color on the table and returns the color index if successful. * If the tolerance is 0 search for the exact match in the palette else search for the * first color that fits in the tolerance range. * See also \ref colorutl. * * \verbatim im.PaletteFindColor(pal: imPalette, color: lightuserdata, tol: number) -> index: number [in Lua 5] \endverbatim * \ingroup palette
Searches for the nearest color on the table and returns the color index if successful. * It looks in all palette entries and finds the minimum euclidian square distance. * If the color matches the given color it returns immediately. * See also \ref colorutl. * * \verbatim im.PaletteFindNearest(pal: imPalette, color: lightuserdata) -> index: number [in Lua 5] \endverbatim * \ingroup palette
Creates a palette of gray scale values. * The colors are arranged from black to white. * * \verbatim im.PaletteGray() -> pal: imPalette [in Lua 5] \endverbatim * \ingroup palette
