convert binary data into java or c++ sourcecode for easy integration in your project, with the free sfk bin-to-src command for Windows, Mac OS X, Linux and Raspberry Pi.

• Download the free Swiss File Knife Base from Sourceforge.
• Open the Windows CMD command line, Mac OS X Terminal or Linux shell.
• OS X : type mv sfk-mac-64.exe sfk and chmod +x sfk then ./sfk
• Linux: type mv sfk-linux-64.exe sfk and chmod +x sfk then ./sfk. OS X and Linux syntax may differ, check the help within the tool.

sfk bin-to-src [...] infile outfile namePrefix

create sourcefile containing a binary data block. the outfile
will contain variable definitions beginning with namePrefix.

options
   -java       create java source code output, default is C.
   -class      java: create a fully compilable class with a short
               demo source code how to write the data to a file.
   -pack       C source: compress data with a simple RLE scheme.
   -hex        C source: produce hex numbers instead of decimal.
   -append     do not overwrite output, but append to it.
   -recsize=n  java: define number of bytes per record used
               within the raw data. default is 500. higher values
               produce less records, which may help if you get
               a "code too large" error during java compile.

further commands
   sfk clipsrc   convert clipboard text to C    style source code
   sfk clipphp   convert clipboard text to PHP  style source code
   sfk clipjava  convert clipboard text to Java style source code
   ... add +toclip to copy converted result back to clipboard.

examples
   sfk bin-to-src myimg.dat imgsrc.cpp img01
      create C source code containing content from myimg.dat.

   sfk bin-to-src -java -class myimg.dat imgdata.java imgdata
      create a Java class "imgdata" with myimg.dat content.
