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.

       --dither-rgb16
              If  specified,  images rendered to RGB16 surfaces are dithered. This reduces banding caused by the
              limited colorspace. This option has no effect for other pixel-formats than RGB16.

       --transparent=AARRGGBB
              If specified, completely transparent pixels are set to this color value.  This may be  useful  for
              color keying and to work around bugs in graphics driver.

       --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.
