README for libdmtx-ruby version 0.7.2 - September 4, 2009
-----------------------------------------------------------------
libdmtx-ruby is a Ruby wrapper for libdmtx that was written by
Romain Goyet and is distributed as part of the libdmtx package.
1. libdmtx Installation
-----------------------------------------------------------------
libdmtx must be installed on your system before installing and
running the Ruby wrapper. Refer to the General Instructions for
this.
2. RMagick Installation
-----------------------------------------------------------------
In addition to libdmtx, the libdmtx Ruby wrapper also relies on
RMagick, available at:
http://rmagick.rubyforge.org/
3. libdmtx-ruby Installation
-----------------------------------------------------------------
$ ruby extconf.rb --with-dmtx-dir=/same/path/as/libdmtx
$ make clean
$ make
4. Usage
-----------------------------------------------------------------
Once the plug-in is built, you can toy around with the "test.rb"
sample script. It demonstrates both reading and writing.
Reading:
$ ruby test.rb /path/to/an/image.file
Writing:
$ ruby test.rb
It will write something to "output.png".
