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
   blitted 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
          variables.  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.
          Possible 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.
