generate_optimized_palette(3alleg4)				  Allegro manual			       generate_optimized_palette(3alleg4)

NAME

       generate_optimized_palette - Generates an optimized palette for a bitmap. 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 version 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 bitmap, 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.
