使用python创建标准条码。不需要外部模块（包括可选的PIL支持）。
tiqetsbarcode的Python项目详细描述
维瓦库迪 是pyBarcode的叉 项目。
这个库提供了一种简单的方法，只使用 python标准库。创建为SVG对象的条形码。
在https://github.com/kxepal/viivakoodi/issues/报告错误
要求
- Setuptools/distribute for installation (new in version 0.7beta4)
- Python 2.6 or above (including Python 3.x)
- On Python 2.6, 3.0, 3.1: argparse (for the commandline script)
- Program to open SVG objects (your browser should do it)
- Optional: PIL to render barcodes as images (PNG, JPG, …)
安装
确保安装了setuptools/distribute。
将下载的文件cd解压到viivakoodi目录并运行 python setup.py安装。或者复制条形码目录 你的Python。
最好的方法是使用pip:pip install viivakoodi。
提供的条形码
EAN-8、EAN-13、UPC-A、JAN、ISBN-10、ISBN-13、ISSN、代码39、代码128、PZN
待办事项
- Add documentation
- Add more codes
- Improve Python 3 support
- Add simple GUI
用法
交互式：
>>> import barcode
>>> barcode.PROVIDED_BARCODES
[u'code39', u'code128', u'ean', u'ean13', u'ean8', u'gs1', u'gtin',
u'isbn', u'isbn10', u'isbn13', u'issn', u'jan', u'pzn', u'upc', u'upca']
>>> EAN = barcode.get_barcode_class('ean13')
>>> EAN
<class 'barcode.ean.EuropeanArticleNumber13'>
>>> ean = EAN(u'5901234123457')
>>> ean
<barcode.ean.EuropeanArticleNumber13 object at 0x00BE98F0>
>>> fullname = ean.save('ean13_barcode')
>>> fullname
u'ean13_barcode.svg'
# Example with PNG
>>> from barcode.writer import ImageWriter
>>> ean = EAN(u'5901234123457', writer=ImageWriter())
>>> fullname = ean.save('ean13_barcode')
u'ean13_barcode.png'
# New in v0.4.2
>>> from StringIO import StringIO
>>> fp = StringIO()
>>> ean.write(fp)
# or
>>> f = open('/my/new/file', 'wb')
>>> ean.write(f) # PIL (ImageWriter) produces RAW format here
# New in v0.5.0
>>> from barcode import generate
>>> name = generate('EAN13', u'5901234123457', output='barcode_svg')
>>> name
u'barcode_svg.svg'
# with file like object
>>> fp = StringIO()
>>> generate('EAN13', u'5901234123457', writer=ImageWriter(), output=fp)
>>>
现在在图形应用程序中或在浏览器中打开EAN13_u条码。[SVG PNG] 并查看创建的条形码。就这样。
命令行：
$ pybarcode{2,3} create "My Text" outfile
New barcode saved as outfile.svg.
$ pybarcode{2,3} create -t png "My Text" outfile
New barcode saved as outfile.png.
Try `pybarcode -h` for help.
更改日志
| v0.8: | Code 128 added. Data for charsets and bars moved to subpackage barcode.charsets. |
|---|---|
| v0.7: | Fixed some issues with fontsize and fontalignment. Added Python 3 support. It’s not well tested yet, but the tests run without errors with Python 3.3. Commandline script added. |
| v0.6: | Changed save and write methods to take the options as a dict not as keyword arguments (fix this in your code). Added option to left align the text under the barcode. Fixed bug with EAN13 generation. |
| v0.5.0: | Added new generate function to do all generation in one step. Moved writer from a subpackage to a module (this breaks some existing code). UPC is now rendered as real UPC, not as EAN13 with the leading “0”. |
| v0.4.3: | Fixed bug in new write method (related to PIL) and updated docs. |
| v0.4.2: | Added write method to support file like objects as target. |
| v0.4.1: | Bugfix release. Removed redundancy in input validation. EAN8 was broken. It now works as expected. |
| v0.4: | Removed **options from writers __init__ method. These options never had effect. They were always overwritten by default_options. New config option available: text_distance (the distance between barcode and text). |
| v0.4b2: | Basic documentation included. The barcode object now has a new attribute called raw to have the rendered output without saving to disk. |
| v0.4b1: | Support for rendering barcodes as images is implemented. PIL is required to use it. |
| v0.3: | Compression for SVG output now works. |
| v0.3b1: | Writer API has changed for simple adding new (own) writers. SVG output is now generated with xml.dom module instead of stringformatting (makes it more robust). |
| v0.2.1: | API of render changed. Now render takes keyword arguments instead of a dict. |
| v0.2: | More tests added. |
| v0.1: | First release. |
