NAME

       exxfade - Truecolor image loading and fades. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example exxfade

DESCRIPTION

       This  program  demonstrates  how to load and display bitmap files in truecolor video modes, and how to crossfade between them.  You have to
       use this example from the command line to specify as parameters a number of graphic files. Use at least two  files  to  see  the  graphical
       effect. The example will crossfade from one image to another with each key press until you press the ESC key.

NAME

       extrans - Lighting and translucency effects. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example extrans

DESCRIPTION

       This program demonstrates how to use the lighting and translucency functions. The first part of the example will show a dark screen illumi-
       nated by a spotlight you can move with your mouse. After a key press the example shows the full bitmap and the spotlight changes  to  be  a
       reduced version of the background with 50% of translucency.

       The  translucency  effect is easy to do in all color depths.  However, the lighting effect has to be performed in a different way depending
       on whether the screen is in 8bit mode or another color depth. This is because additive drawing mode uses a different set  of  routines  for
       truecolor modes.
