generate_optimized_palette(3)	Allegro	manual	 generate_optimized_palette(3)

NAME
       generate_optimized_palette  - Generates an optimized palette for	a bit-
       map. Allegro game programming library.

SYNOPSIS
       #include	<allegro.h>

       int generate_optimized_palette(BITMAP *bmp,  PALETTE  pal,  const  char
       rsvd[PAL_SIZE]);

DESCRIPTION
       Generates  a 256-color palette suitable for making a reduced color ver-
       sion of the specified truecolor image. The rsvd parameter points	 to  a
       table  indicating  which	 colors	it is allowed to modify: zero for free
       colors which may	be set to whatever the optimiser likes,	negative  val-
       ues  for	 reserved colors which cannot be used, and positive values for
       fixed palette entries that must not be changed, but can be used in  the
       optimisation.

RETURN VALUE
       Returns	the number of different	colors recognised in the provided bit-
       map, zero if the	bitmap is not a	truecolor image	or there wasn't	enough
       memory to perform the operation,	and negative if	there was any internal
       error in	the color reduction code.
