create_color_table(3)

NAME
create_color_table

SYNOPSIS
#include <allegro.h>

void create_color_table(COLOR_MAP *table, const PALETTE pal, void (*blend)(PALETTE pal, int x, int y, RGB *rgb), void (*callback)(int pos));

DESCRIPTION
Fills the specified color mapping table with lookup data for doing customised effects with the specified palette, calling the blend function to determine the results of each color combination. Your blend routine will be passed a pointer to the palette and the two colors which are to be combined, and should fill in the RGB structure with the desired result in 0-63 format. Allegro will then search the palette for the closest match to the RGB color that you requested, so it doesn't matter if the palette has no exact match for this color. If the callback function is not NULL, it will be called 256 times during the calculation, allowing you to display a progress indicator.
