To install libdmtx first of all we have to configured the machine compatible to libdmtx library:
for that you have to install some python packages.
The required packages are :
(1) python-dev
This will include the all header file of the c which is requierd for libdmtx library e.g python.h
sudo apt-get install python-dev
(2) git
This will install the git which is repository
sudo apt-get install git
(3) libdmtx-utils
libdmtx-utils is required for the libdmtx library which includes c file and all header file
sudo apt-get install libdmtx-utils
(4) libdmtx-dev
libdmtx-dev is required for the libdmtx python wrapper.
sudo apt-get install libdmtx-dev
Now we have to setup the libdmtx library,
(1) first change the directory to
cd /usr/share/doc/libdmtx-dev/examples/python
(2)unzip pydmtx.py.gz
sudo gunzip pydmtx.py.gz
(3)unzip pydmtxmodule.c.gz
sudo gunzip pydmtxmodule.c.gz
(4) installing the setup of libdmtx
sudo python setup.py install
(5) Thats it!!
now test if the installation
run this python code in your python interpreter:
from pydmtx import DataMatrix
from PIL import Image
# Write a Data Matrix barcode
dm_write = DataMatrix()
dm_write.encode("Hello, world!")
dm_write.save("/home/hello.png", "png")
# Read a Data Matrix barcode
dm_read = DataMatrix()
img = Image.open("/home/hello.png")
print dm_read.decode(img.size[0], img.size[1], buffer(img.tostring()))
print dm_read.count()
print dm_read.message(1)
print dm_read.stats(1)
