NAME
       directfb-csource - C code generation utility for DirectFB surfaces

SYNOPSIS
       directfb-csource [options] <imagefiles>

DESCRIPTION
       directfb-csource  is  a  small utility that reads PNG (Portable Network
       Graphics) image files and generates C code that can be used to  compile
       an  image  into  a  DirectFB application.  Below is a simple example to
       illustrate this.

       If multiple PNG image files are passed to  directfb-csource,  they  are
       combined  into a single surface. The different images can then be blit-
       ted from this surface using  the  array  of  rectangles  that  is  also
       dumped. This can be useful for example for icons or sprites.

OPTIONS
       --name=identifier
              Specifies  the  identifier name (prefix) for the generated vari-
              ables.  If this option is not used, the identifier is  generated
              from  the  filename.  You have to specify an identifer name when
              processing multiple images.

       --format=pixelformat
              Specifies the pixel-format of the generated inline surface. Pos-
              sible  values  are  ARGB, RGB32, RGB24, RGB16, RGB15, RGB332, A8
              and LUT8.  By default the format is ARGB if the PNG image has an
              alpha channel or RGB32 otherwise.

       --version
              Output version information.

       --help Print brief help and exit.

EXAMPLE
       Generate a header file from a PNG image file:

            directfb-csource --name=foo foo.png > foo.h

       Include  the  generated header in your application and create a surface
       using the surface description from the header file:

         #include <directfb.h>
         #include "foo.h"

         IDirectFB        *dfb;
         IDirectFBSurface *surface;

         ...

         dfb->CreateSurface( dfb, &foo_desc, &surface );

OTHER INFO
       directfb-csource was inspired by and uses code from gdk-pixbuf-csource,
       a similar program written by Tim Janik.
