bestfit_color(3alleg4)						  Allegro manual					    bestfit_color(3alleg4)

NAME

       bestfit_color - Finds a palette color fitting the requested RGB values. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int bestfit_color(const PALETTE pal, int r, int g, int b);

DESCRIPTION

       Searches  the specified palette for the closest match to the requested color, which are specified in the VGA hardware 0-63 format. Normally
       you should call makecol8() instead, but this lower level function may be useful if you need to use  a  palette  other  than  the  currently
       selected one, or specifically don't want to use the rgb_map lookup table.

RETURN VALUE

       Returns the index of the palette for the closest match to the requested color.

NAME

       makecol8,  makecol15,  makecol16, makecol24, makecol32 - Converts an RGB value into a display dependent pixel format. Allegro game program-
       ming library.

SYNOPSIS

       #include <allegro.h>

       int makecol8(int r, int g, int b);

       int makecol15(int r, int g, int b);

       int makecol16(int r, int g, int b);

       int makecol24(int r, int g, int b);

       int makecol32(int r, int g, int b);

DESCRIPTION

       These functions convert colors from a hardware independent form (red, green, and blue values ranging 0-255) into various display  dependent
       pixel formats. Converting to 15, 16, 24, or 32-bit formats only takes a few shifts, so it is fairly efficient. Converting to an 8-bit color
       involves searching the palette to find the closest match, which is quite slow unless you have set up an	RGB  mapping  table  (see  below).
       Example:

	  /* 16 bit color version of green. */
	  int green_color = makecol16(0, 255, 0);

RETURN VALUE

       Returns the requested RGB triplet in the specified color depth.
