make
(content, error=None, version=None, mode=None, mask=None, encoding=None, eci=False, micro=None, boost_error=True)¶ Creates a (Micro) QR Code.
This is main entry point to create QR Codes and Micro QR Codes.
Aside from content, all parameters are optional and an optimal (minimal) (Micro) QR Code with a maximal error correction level is generated.
Parameters: - content¶ (str, int, bytes) – The data to encode. Either a Unicode string, an integer or bytes. If bytes are provided, the encoding parameter should be used to specify the used encoding.
- error¶ (str or None) –
Error correction level. If
None
(default), error correction levelL
is used (note: Micro QR Code version M1 does not support any error correction. If an explicit error correction level is used, a M1 QR Code won’t be generated). Valid values:None
(allowing generation of M1 codes or use error correction level “L” or better seeboost_error
), “L”, “M”, “Q”, “H” (error correction level “H” isn’t available for Micro QR Codes).Error correction level Error correction capability L (Segno’s default unless version M1) recovers 7% of data M recovers 15% of data Q recovers 25% of data H (not available for Micro QR Codes) recovers 30% of data Higher error levels may require larger QR Codes (see also
version
parameter).The error parameter is case insensitive.
See also the
boost_error
parameter. - version¶ (int, str or None) – QR Code version. If the value is
None
(default), the minimal version which fits for the input data will be used. Valid values: “M1”, “M2”, “M3”, “M4” (for Micro QR Codes) or an integer between 1 and 40 (for QR Codes). The version parameter is case insensitive. - mode¶ (str or None) –
“numeric”, “alphanumeric”, “byte”, or “kanji”. If the value is
None
(default) the appropriate mode will automatically be determined. If version refers a to Micro QR Code, this function may raise aValueError
if the provided mode is not supported.Mode (Micro) QR Code Version numeric 1 - 40, M1, M2, M3, M4 alphanumeric 1 - 40, M2, M3, M4 byte 1 - 40, M3, M4 kanji 1 - 40, M3, M4 The mode parameter is case insensitive.
- mask¶ (int or None) – Data mask. If the value is
None
(default), the appropriate data mask is chosen automatically. If the mask parameter is provided, this function may raise aValueError
if the mask is invalid. - encoding¶ (str or None) – Indicates the encoding in mode “byte”. By default
(encoding is
None
) the implementation tries to use the standard conform ISO/IEC 8859-1 encoding and if it does not fit, it will use UTF-8. Note that no ECI mode indicator is inserted by default (seeeci
). The encoding parameter is case insensitive. - eci¶ (bool) – Indicates if binary data which does not use the default
encoding (ISO/IEC 8859-1) should enforce the ECI mode. Since a lot
of QR Code readers do not support the ECI mode, this feature is
disabled by default and the data is encoded in the provided
encoding using the usual “byte” mode. Set eci to
True
if an ECI header should be inserted into the QR Code. Note that the implementation may not know the ECI designator for the provided encoding and may raise an exception if the ECI designator cannot be found. The ECI mode is not supported by Micro QR Codes. - micro¶ (bool or None) – If
version
isNone
(default) this parameter can be used to allow the creation of a Micro QR Code. If set toFalse
, a QR Code is generated. If set toNone
(default) a Micro QR Code may be generated if applicable. If set toTrue
the algorithm generates a Micro QR Code or raises an exception if the mode is not compatible or the content is too large for Micro QR Codes. - boost_error¶ (bool) – Indicates if the error correction level may be
increased if it does not affect the version (default:
True
). If set toTrue
, theerror
parameter is interpreted as minimum error level. If set toFalse
, the resulting (Micro) QR Code uses the provided error level (or the default error correction level, if error isNone
)
Raises: ValueError
orDataOverflowError
: In case the data does not fit into a (Micro) QR Code or it does not fit into the providedversion
.Return type:
-
segno.
make_qr
(content, error=None, version=None, mode=None, mask=None, encoding=None, eci=False, boost_error=True)¶ Creates a QR Code (never a Micro QR Code).
See
make()
for a description of the parameters.Return type: QRCode
-
segno.
make_micro
(content, error=None, version=None, mode=None, mask=None, encoding=None, boost_error=True)¶ Creates a Micro QR Code.
See
make()
for a description of the parameters.Note: Error correction level “H” isn’t available for Micro QR Codes. If used, this function raises a
segno.ErrorLevelError
.Return type: QRCode
-
segno.
make_sequence
(content, error=None, version=None, mode=None, mask=None, encoding=None, boost_error=True, symbol_count=None)¶ Creates a sequence of QR Codes using the Structured Append mode.
If the content fits into one QR Code and neither
version
norsymbol_count
is provided, this function may return a sequence with one QR Code which does not use the Structured Append mode. Otherwise a sequence of 2 .. n (max. n = 16) QR Codes is returned which use the Structured Append mode.The Structured Append mode allows to split the content over a number (max. 16) QR Codes.
The Structured Append mode isn’t available for Micro QR Codes, therefor the returned sequence contains QR Codes, only.
Since this function returns an iterable object, it may be used as follows:
for i, qrcode in enumerate(segno.make_sequence(data, symbol_count=2)): qrcode.save('seq-%d.svg' % i, scale=10, color='darkblue')
The number of QR Codes is determined by the version or symbol_count parameter.
See
make()
for a description of the other parameters.Parameters: symbol_count¶ (int) – Number of symbols. Return type: QRCodeSequence
-
class
segno.
QRCode
(code)¶ Represents a (Micro) QR Code.
-
version
¶ (Micro) QR Code version. Either a string (“M1”, “M2”, “M3”, “M4”) or an integer in the range of 1 .. 40.
Return type: str or int
-
error
¶ Error correction level; either a string (“L”, “M”, “Q”, “H”) or
None
if the QR Code provides no error correction (Micro QR Code version M1)Return type: str
-
mode
¶ String indicating the mode (“numeric”, “alphanumeric”, “byte”, “kanji”). May be
None
if multiple modes are used.Return type: str or None
-
designator
¶ Returns the version and error correction level as string V-E where V represents the version number and E the error level.
Return type: str
-
default_border_size
¶ Indicates the default border size aka quiet zone.
QR Codes have a quiet zone of four light modules, while Micro QR Codes have a quiet zone of two light modules.
Return type: int
-
symbol_size
(scale=1, border=None)¶ Returns the symbol size (width x height) with the provided border and scaling factor.
Parameters: - scale¶ (int or float) – Indicates the size of a single module (default: 1). The size of a module depends on the used output format; i.e. in a PNG context, a scaling factor of 2 indicates that a module has a size of 2 x 2 pixel. Some outputs (i.e. SVG) accept floating point values.
- border¶ (int) – The border size or
None
to specify the default quiet zone (4 for QR Codes, 2 for Micro QR Codes).
Return type: tuple (width, height)
-
matrix_iter
(scale=1, border=None, verbose=False)¶ Returns an iterator over the matrix which includes the border.
The border is returned as sequence of light modules. Dark modules are reported as
0x1
, light modules have the value0x0
.The following example converts the QR Code matrix into a list of lists which use boolean values for the modules (True = dark module, False = light module):
>>> import segno >>> qr = segno.make('The Beatles') >>> width, height = qr.symbol_size(scale=2) >>> res = [] >>> # Scaling factor 2, default border >>> for row in qr.matrix_iter(scale=2): >>> res.append([col == 0x1 for col in row]) >>> width == len(res[0]) True >>> height == len(res) True
If verbose is
True
, the iterator returns integer constants which indicate the type of the module, i.e.segno.consts.TYPE_FINDER_PATTERN_DARK
,segno.consts.TYPE_FINDER_PATTERN_LIGHT
,segno.consts.TYPE_QUIET_ZONE
etc.To check if the returned module type is dark or light, use:
if mt >> 8: print('dark module') if not mt >> 8: print('light module')
Parameters: - scale¶ (int) – The scaling factor (default:
1
). - border¶ (int) – The size of border / quiet zone or
None
to indicate the default border. - verbose¶ (bool) – Indicates if the type of the module should be returned
instead of
0x1
and0x0
values. Seesegno.consts
for the return values. This feature is currently in EXPERIMENTAL state.
Raises: ValueError
if the scaling factor or the border is invalid (i.e. negative).- scale¶ (int) – The scaling factor (default:
-
show
(delete_after=20, scale=10, border=None, dark='#000', light='#fff')¶ Displays this QR code.
This method is mainly intended for debugging purposes.
This method saves QR code as an image (by default with a scaling factor of 10) to a temporary file and opens it with the standard PNG viewer application or within the standard webbrowser. The temporary file is deleted afterwards (unless
delete_after
is set toNone
).If this method does not show any result, try to increase the
delete_after
value or set it toNone
Parameters: - delete_after¶ (int or None) – Time in seconds to wait till the temporary file is deleted.
- scale¶ (int) – Integer indicating the size of a single module.
- border¶ (int or None) – Integer indicating the size of the quiet zone.
If set to
None
(default), the recommended border size will be used. - dark¶ – The color of the dark modules (default: black).
- light¶ – The color of the light modules (default: white).
-
svg_data_uri
(xmldecl=False, encode_minimal=False, omit_charset=False, nl=False, **kw)¶ Converts the QR Code into a SVG data URI.
The XML declaration is omitted by default (set
xmldecl
toTrue
to enable it), further the newline is omitted by default (setnl
toTrue
to enable it).Aside from the missing out parameter, the different xmldecl and nl default values, and the additional parameters
encode_minimal
andomit_charset
, this method uses the same parameters as the usual SVG serializer, seesave()
and the available SVG parametersParameters: - xmldecl¶ (bool) – Indicates if the XML declaration should be
serialized (default:
False
) - encode_minimal¶ (bool) – Indicates if the resulting data URI should use minimal percent encoding (disabled by default).
- omit_charset¶ (bool) – Indicates if the
;charset=...
should be omitted (disabled by default) - nl¶ (bool) – Indicates if the document should have a trailing newline
(default:
False
)
Return type: - xmldecl¶ (bool) – Indicates if the XML declaration should be
serialized (default:
-
png_data_uri
(**kw)¶ Converts the QR Code into a PNG data URI.
Uses the same keyword parameters as the usual PNG serializer, see
save()
and the available PNG parametersReturn type: str
-
terminal
(out=None, border=None)¶ Serializes the matrix as ANSI escape code.
Under Windows, no ANSI escape sequence is generated but the Windows API is used unless
out
is a writable object or using WinAPI fails.Parameters:
-
save
(out, kind=None, **kw)¶ Serializes the QR Code in one of the supported formats. The serialization format depends on the filename extension.
Common keywords
Name Description scale Integer or float indicating the size of a single module. Default: 1. The interpretation of the scaling factor depends on the serializer. For pixel-based output (like PNG) the scaling factor is interepreted as pixel-size (1 = 1 pixel). EPS interprets 1
as 1 point (1/72 inch) per module. Some serializers (like SVG) accept float values. If the serializer does not accept float values, the value will be converted to an integer value (note: int(1.6) == 1).border Integer indicating the size of the quiet zone. If set to None
(default), the recommended border size will be used (4
for QR Codes,2
for a Micro QR Codes). A value of0
indicates that border should be omitted.dark A string or tuple representing a color value for the dark modules. The default value is “black”. The color can be provided as (R, G, B)
tuple, as web color name (like “red”) or in hexadecimal format (#RGB
or#RRGGBB
). Some serializers (i.e. SVG and PNG) accept an alpha transparency value like#RRGGBBAA
.light A string or tuple representing a color for the light modules. See dark for valid values. The default value depends on the serializer. SVG uses no color ( None
) for light modules by default, other serializers, like PNG, use “white” as default light color.Module Colors
Name Description finder_dark Color of the dark modules of the finder patterns Default: undefined, use value of “dark” finder_light Color of the light modules of the finder patterns Default: undefined, use value of “light” data_dark Color of the dark data modules Default: undefined, use value of “dark” data_light Color of the light data modules. Default: undefined, use value of “light”. version_dark Color of the dark modules of the version information.

Default: undefined, use value of “dark”. quiet_zone Color of the quiet zone / border. Default: undefined, use value of “light”. Scalable Vector Graphics (SVG)
All common keywords and module colors are supported.
Name Description out Filename or io.BytesIO
kind “svg” or “svgz” (to create a gzip compressed SVG) scale integer or float dark Default: “#000” (black) None
is a valid value. If set toNone
, the resulting path won’t have a “stroke” attribute. The “stroke” attribute may be defined via CSS (external). If an alpha channel is defined, the output depends of the used SVG version. For SVG versions >= 2.0, the “stroke” attribute will have a value like “rgba(R, G, B, A)”, otherwise the path gets another attribute “stroke-opacity” to emulate the alpha channel. To minimize the document size, the SVG serializer uses automatically the shortest color representation: If a value like “#000000” is provided, the resulting document will have a color value of “#000”. If the color is “#FF0000”, the resulting color is not “#F00”, but the web color name “red”.light Default value None
. If this parameter is set to another value, the resulting image will have another path which is used to define the color of the light modules. If an alpha channel is used, the resulting path may have a “fill-opacity” attribute (for SVG version < 2.0) or the “fill” attribute has a “rgba(R, G, B, A)” value.xmldecl Boolean value (default: True
) indicating whether the document should have an XML declaration header. Set toFalse
to omit the header.svgns Boolean value (default: True
) indicating whether the document should have an explicit SVG namespace declaration. Set toFalse
to omit the namespace declaration. The latter might be useful if the document should be embedded into a HTML 5 document where the SVG namespace is implicitly defined.title String (default: None
) Optional title of the generated SVG document.desc String (default: None
) Optional description of the generated SVG document.svgid A string indicating the ID of the SVG document (if set to None
(default), the SVG element won’t have an ID).svgclass Default: “segno”. The CSS class of the SVG document (if set to None
, the SVG element won’t have a class).lineclass Default: “qrline”. The CSS class of the path element (which draws the dark modules (if set to None
, the path won’t have a class).omitsize Indicates if width and height attributes should be omitted (default: False
). If these attributes are omitted, aviewBox
attribute will be added to the document.unit Default: None
Indicates the unit for width / height and other coordinates. By default, the unit is unspecified and all values are in the user space. Valid values: em, ex, px, pt, pc, cm, mm, in, and percentages (any string is accepted, this parameter is not validated by the serializer)encoding Encoding of the XML document. “utf-8” by default. svgversion SVG version (default: None
). If specified (a float), the resulting document has an explicit “version” attribute. If set toNone
, the document won’t have a “version” attribute. This parameter is not validated.compresslevel Default: 9. This parameter is only valid, if a compressed SVG document should be created (file extension “svgz”). 1 is fastest and produces the least compression, 9 is slowest and produces the most. 0 is no compression. draw_transparent Indicates if transparent SVG paths should be added to the graphic (default: False
)nl Indicates if the document should have a trailing newline (default: True
)Portable Network Graphics (PNG)
This writes either a grayscale (maybe with transparency) PNG (color type 0) or a palette-based (maybe with transparency) image (color type 3). If the dark / light values are
None
, white or black, the serializer chooses the more compact grayscale mode, in all other cases a palette-based image is written.All common keywords and module colors are supported.
Name Description out Filename or io.BytesIO
kind “png” scale integer dark Default: “#000” (black) None
is a valid value iff light is notNone
. If set toNone
, the dark modules become transparent.light Default value “#fff” (white) See keyword “dark” for further details. compresslevel Default: 9. Integer indicating the compression level for the IDAT
(data) chunk. 1 is fastest and produces the least compression, 9 is slowest and produces the most. 0 is no compression.dpi Default: None
. Specifies the DPI value for the image. By default, the DPI value is unspecified. Please note that the DPI value is converted into meters (maybe with rounding errors) since PNG does not support the unit “dots per inch”.Encapsulated PostScript (EPS)
All common keywords are supported.
