generate_optimized_palette(3)   Allegro manual   generate_optimized_palette(3)



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
       values 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.
