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.
