segno-quark 0.1.0

Convert Segno's (Micro) QR Codes into more advanced SVG documents

Segno Quark: Plugin for creating more advanced SVG documents

This (experimental) Segno plugin changes the default SVG output in different ways (i.e. applying SVG filters).

Tested under PyPy, Python 2.7 and Python 3.4. Unlike Segno itself, this package does not work with Python 2.6.

Installation

Use pip to install this quark from PyPI:

$ pip install segno

Usage

One installed, the quark is automatically detected as Segno plugin and therefore available via qrcode.to_XXX(...).

Available converters

All converters use the same keyword parameters as Segno’s SVG serializer, see segno.QRCode.save() for details.

ETree

Creates a SVG QR Code and returns the SVG document as xml.etree.ElementTree.

Usage: to_etree

This converter provides no additional keyword arguments.

Pacman

Creates a QR Code with a smiley (and optional ghosts).

Usage: to_pacman

Keyword	Description
pacman_color	Color of the smiley, default: #fc0
dot_color	Color of the dots which the smiley should eat, default: #fc0
ghosts	Number of ghosts, default: 5. If set to 0, no ghost appears. Note: Setting this a very high value may cause an infinite loop iff number of ghosts > number of available dark modules. Additionally, the QR Code may not be readable by common QR Code decoders. The positions of the ghosts are choosen at random.
ghost_colors	A tuple of colors which the ghosts may get. Default: ('#ff0c13', '#f2aeaf', '#1bb1e6', '#f97e16') Not all colors may be used, the colors for the ghosts are choosen at random.

Example:

>>> import segno
>>> qr = segno.make_qr('Ob-La-Di, Ob-La-Da')
>>> qr.to_pacman('obladioblada.svg', scale=10, ghosts=7)

Result:

Glow

Creates a QR Code with a “glow” effect.

Usage: to_glow

Keyword	Description
filter_id	Indicates the id of the filter, default: segno-glow
deviation	Indicates the standard deviation for the blur operation, default: .6

Example:

>>> import segno
>>> qr = segno.make_qr('Ob-La-Di, Ob-La-Da')
>>> qr.to_glow('obladioblada.svg', scale=10, color='darkblue')

Result:

Blur

Creates a QR Code with a “blur” effect.

Usage: to_blur

Keyword	Description
filter_id	Indicates the id of the filter, default: segno-blur
deviation	Indicates the standard deviation for the blur operation, default: .3

Example:

>>> import segno
>>> qr = segno.make_qr('Ob-La-Di, Ob-La-Da')
>>> qr.to_blur('obladioblada.svg', scale=10, color='darkred')
