hudora / hubarcode Goto Github PK

My code as follows:

def create_qr_code_pic(data):
code_str = "!|"
code_str += data+"|"
code_str += "@"

(dir,file_name) = get_unique_file_name2(file_pre="qr")
code_image_path = os.path.join(settings.MEDIA_ROOT,'uploads',dir)
if not os.path.exists(code_image_path):
    os.mkdir(code_image_path)
code_image_file_name = '%s/%s.png' % (code_image_path, file_name)

ENCODER = QRCodeEncoder(code_str.encode('gbk'))
ENCODER.save(code_image_file_name)

return '%s/%s.png' % (dir, file_name)

and the error message:

Hi,

I can get the data matrix images in a 80x80 pixel format but i'm not able to change the size of this image either increase or decrease the image by , lets say 50%(40x40 pixel) or 150%(120x120 pixel).

i have tried altering the .height and .width parameter but i think they are for bar codes and not for data matrix.

is there a solution for this?

Sir,
First of all I would really like to thank you for making such a nice and good script for developing 2D barcodes and keeping it in open license formats.
Actually I am trying to build a simple application for myself, and for a kind of secrecy, I want the answers (output) to be printed and circulated using the datamatrix encodings. As the datamatrix encoding procedure is defined by ISO and is not freely available, I looked upon your code for help.
I have seen the examples and it was really easy to understand how to implement your script. But the problem is I have dealt with python in only its 3.x version and I do not know much about 2.x It would be really helpful if you could tell, till when would you release the script in 3.x or help in converting the present script (only the datamatrix part) in 3.x
Thank you very much for reading my mail,

This code produces the same bardcodes (the readable text changes, but the barcodes are the same). The first is missing the 9.

from hubarcode.code128 import Code128Encoder

encoder = Code128Encoder('123456789')
encoder.save('test1.png')

encoder = Code128Encoder('12345678')
encoder.save('test2.png')

hi,

please throws exception instead of sys.exit, when data is too big.

may stop a running web service... :)

The title shall say it all.

Some documentation apart from the samples would be nice

this took me a while to figure out:

the qrcode implementation won't work if installed via the current trunk , because the qrcode_data directory isn't installed along with it.

the qrcode_generate_Data.py script doesn't seem to work either, because it doesn't like the way stuff is laid out

my inelegant fix was to migrate the qrcode_data that was in trunk into the python egg.

could you fix these? thank you!

Any chance we can get a new release cut and uploaded to PyPI? It's been two years since the last one, and certain changes (#16 in particular) would be nice to have. Thanks!

Please add licensing information to the library. Preferably an open source license. :-)

It would be nice if there was some usage documentation for this library! Specifically options and import steps would be appreciated.

When using pip install huBarcode, sub-packages are installed in root lib dir.

Example:
/usr/local/lib/python2.6/dis-packages/code128

Should be
/usr/local/lib/python2.6/dis-packages/hubarcode/code128

Also, 'fonts' directory is not installed.

I'm having trouble render an image of QR code (works for DataMatrix).

from hubarcode.qrcode import QRCodeEncoder

qr = QRCodeEncoder("m103")
qr_raw_ascii = qr.get_ascii()
print(qr_raw_ascii) # works
qr_raw_img = qr.get_imagedata()
print(qr_raw_img) # prints error listed below

Traceback (most recent call last):
  File "D:/py_workspace/otf_barcode/source/test", line 6, in <module>
    qr_raw_img = qr.get_imagedata()
  File "C:\Python27\lib\site-packages\hubarcode\qrcode\__init__.py", line 44, in get_imagedata
    imagedata = qrc.get_imagedata(cellsize)

Am I doing something wrong?

Too bad huBarcode doesn't work with Python3.

I'd submit a patch, but I'm pretty new to libraries and git too so... here is what I did to make huBarcode work for python3 (or... at least the parts I need to generate a datamatrix):

• Example from "hubarcode/datamatrix/init.py":
  from textencoder import TextEncoder
  Must be replaced by this:
  from .textencoder import TextEncoder
  This is only an example. Almost every .py-File needs to be update
• Example from "hubarcode/datamatrix/placement.py", line 105:
  def place_standard_shape(self, (posx, posy), codeword):
  Must be replaced with:
  def place_standard_shape(self, posx_posy, codeword):
  posx, posy = posx_posy
• "hubarcode/datamatrix/renderer.py", the StringIO has been restructured. To Import it in a Python2 and Python3 compatible way use:

try:
from StringIO import StringIO
except ImportError:
from io import StringIO

• Last but not least, remember to install Pillow instead of PIL as PIL isn't Python3 compatible either.

It appears that the install problem not copy hubarcode/qrcode/qrcode_data dir to '/usr/lib/python2.5/site-packages/huBarcode-0.61_r0-py2.5.egg/hubarcode/qrcode/qrcode_data/'.

I've downloaded the latest version of huBarcode from the cheeseshop, and when I attempt to follow the datamatrix sample in the python interpreter, I get an import error.

>>> from hubarcode.datamatrix import DataMatrixEncoder
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\python27\lib\site-packages\hubarcode-0.63-py2.7.egg\hubarcode\datamatrix\__init__.py
", line 39, in <module>
    from renderer import DataMatrixRenderer
  File "c:\python27\lib\site-packages\hubarcode-0.63-py2.7.egg\hubarcode\datamatrix\renderer.py
", line 6, in <module>
    import Image
ImportError: No module named Image

Is there a dependency I'm not aware of?

I use this software and our legal page attributes the correct license. I'm writing a dynamic way of getting the licenses for current versions of the packages we use. One of the strategies is pulling the LICENSE file for a given version from release branches on github or whatever hosting provider the project in question is using.

Currently, the latest (and only) release branch tagged on this project is 0.6.2, even though the PyPI package and commit comments indicate that 0.63 is the latest version. A simple version bump tag would be in order.

Also, the versioning convention should be reviewed and sync'd between github and PyPI. I imagine the "current" version is supposed to be 0.6.3 rather than 0.63.

This package has conflicting license information.

On one hand, the README file states the following:

The code is available under the Apache License, Version 2.0.

On the other, the setup.py file contains the following:

'License :: OSI Approved :: BSD License',

And the README also contains this:

If you worry about copyright you might consider this Software BSD-Licensed.
If you are still worried, you might consider it GPL1/2/3 compatible.

If this package is Apache 2.0 licensed, this is incorrect; the Apache 2.0 license is not compatible with versions of the GPL before v3.

I'd recommend picking a single license, placing the license text in a LICENSE file, and changing all references in the README, setup.py, and elsewhere to match.

Would it be possible to add the possible list of export format? I'm particularly interested to know if it could export as EPS format or SVG format. Thanks!
