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.
