Name

       bin2c — embed data files into C as variables

Syntax

       bin2c  [-C  program-file]  [-D  dir_prefix] [-H header-file] [-G guard-name] [-p num] [-v]
       [--ultra] [--wxbitmap] file...

Description

       bin2c converts files to C variables. It does so by  reading  the  contents  of  each  file
       supplied  on  the argument line and writes out C program code that defines a variable with
       the file's contents.

       hxtools's bin2c implementation supports:

       •   space-efficient encoding of the arbitrary data

       •   multiple input files

       •   creation of either a standalone .h file, or a .c/.h file pair. (See examples below.)

Options

       -C file
              If specified, causes the variable definition to be emitted to the given filename.

       -D dir_prefix
              All filenames on the command line will be prefixed with the given directory.   This
              has  the  implication that files will be searched relative to dir_prefix, while the
              variable name ending up in the C source for an image will remain non-prefixed.

       -G name
              Request that an include guard by the identifier  guard-name  is  emitted  into  the
              header file. If -C was specified and a .c/.h pair is generated, an include guard is
              always emitted, and the -G option can be used to set that name.

       -H file
              The file where the variable  declarations  will  be  emitted  to.  If  -C  was  not
              specified, h-file will not contain any header guard by default, and it will contain
              the variable definition, the latter of which will be marked as static (file scope).

       -p num Strip num leading path components when transforming input paths to variable  names.
              If  num  is negative, that many trailing path components are retained. If -p is not
              specified, the default is -1.

       -v     Be verbose. Show all the names and filenames that bin2c will write.

       --ultra
              Writeout the raw data as a string literal. As the literal contains a  trailing  NUL
              byte,  the size of the array is necessarily also one byte longer than the raw data,
              which you need to account for. (In C, it would be possible to  write  char  x[3]  =
              "ABC", but this leads to an error in C++ where x[4] is required.)

       --wxbitmap
              Generate  C++  code  that  generates wxBitmap objects. (Implies Ultra encoding, and
              deals with it appropriately, too.)

Examples

       To generate a single C header file that behaves like XPM files and which is  suitable  for
       inclusion into a C program file of your own:

       bin2c -H images.h foo.png bar.png

       To generate a .c/.h pair instead, the invocation is:

       bin2c -C images.c foo.png bar.png

       This  will  create  a  C  program  file  "images.c"  containing  all the definitions and a
       "images.h" that your code can use to get ahold of the declarations.

History

       hxtools's bin2c developed from the earlier png2wx.pl utility.
