DESCRIPTION

14       Libqrencode is a library for encoding data in a QR Code symbol, a  kind
15       of 2D symbology that can be scanned by handy terminals such as a mobile
16       phone with CCD. The capacity of QR Code is up to 7000  digits  or  4000
17       characters, and has high robustness.
18
19       Qrencode  is a utility software using libqrencode to encode string data
20       in a QR Code and save as a PNG or EPS image.

OPTIONS

24       -h, --help
25              display help message.
26
27       -o FILENAME, --output=FILENAME
28              write image to FILENAME. If '-' is specified, the result will be
29              output  to  standard  output. If -S is given, structured symbols
30              are written to FILENAME-01.png, FILENAME-02.png, ... (suffix  is
31              removed from FILENAME, if specified)
32
33       -s NUMBER, --size=NUMBER
34              specify the size of dot (pixel). (default=3)
35
36       -l {LMQH}, --level={LMQH}
37              specify  error  collectin  level from L (lowest) to H (highest).
38              (default=L)
39
40       -v NUMBER, --symversion=NUMBER
41              specify the version of the symbol. See SYMBOL VERSIONS for  more
42              information. (default=auto)
43
44       -m NUMBER, --margin=NUMBER
45              specify the width of margin. (default=4)
46
47       -d NUMBER, --dpi=NUMBER
48              specify the DPI of the generated PNG. (default=72)
49
50       -t {PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8,ANSIUTF8}
51       --type={PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8,ANSIUTF8}
52              specify the type of the generated image. (default=PNG)
53
54       -S, --structured
55              make structured symbols. Version must be specified.
56
57       -k, --kanji
58              assume that the input text contains kanji (shift-jis).
59
60       -c, --casesensitive
61              encode lower-case alphabet characters in 8-bit mode. (default)
62
63       -i, --ignorecase
64              ignore case distinctions and use only upper-case characters.
65
66       -8, --8bit
67              encode entire data in 8-bit mode. -k, -c and -i will be ignored.
68
69       -M, --micro
70              encode in a Micro QR Code. (experimental)
71
72       --foreground=RRGGBB[AA]
73       --background=RRGGBB[AA]
74              specify  foreground/background  color  in  hexadecimal notation.
75              6-digit (RGB) or 8-digit (RGBA) form are supported.  Color  out‐
76              put support available only in PNG and SVG.
77
78       -V, --version
79              display the version number and copyrights of the qrencode.
80
81       --verbose
82              display verbose information to stderr.
83
84       [STRING]

SYMBOL VERSIONS

90       The symbol versions of QR Code range from  Version  1  to  Version  40.
91       Each version has a different module configuration or number of modules,
92       ranging from Version 1 (21 x 21 modules) up to Version 40  (177  x  177
93       modules).   Each  higher  version number comprises 4 additional modules
94       per side by default.   See  http://www.qrcode.com/en/about/version.html
95       for a detailed version list.

EXAMPLES

99       qrencode -l L -v 1 -o output.png 'Hello, world!'
100              encode into a symbol version 1, level L.
101
102       qrencode -iSv 1 --output=output.png
103              read  standard  input  and  encode it into a structured-appended
104              symbols in case-insensitive mode.
105
106       cat bigfile.txt | qrencode -S -v 40 -l L -o output.png
107              encode into a symbol version 40, level L.
