create_blender_table(3)         Allegro manual         create_blender_table(3)

NAME
       create_blender_table - Emulates truecolor blender effects in paletted
       modes. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void create_blender_table(COLOR_MAP *table, const PALETTE pal, void
       (*callback)(int pos));

DESCRIPTION
       Fills the specified color mapping table with lookup data for doing a
       paletted equivalent of whatever truecolor blender mode is currently
       selected. After calling set_trans_blender(), set_blender_mode(), or any
       of the other truecolor blender mode routines, you can use this function
       to create an 8-bit mapping table that will have the same results as
       whatever 24-bit blending mode you have enabled.
