+----------+ | qrencode | +----------+ qrencode is a utility software using libqrencode to encode string data in a QR Code and save as a PNG image. https://fukuchi.org/works/qrencode/ +---------+ | Manpage | +---------+ QRENCODE(1) General Commands Manual QRENCODE(1) NAME qrencode - Encode input data in a QR Code and save as a PNG or EPS im- age. SYNOPSIS qrencode [-o FILENAME] [OPTION]... [STRING] DESCRIPTION Libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness. Qrencode is a utility software using libqrencode to encode string data in a QR Code and save as a PNG or EPS image. OPTIONS -h, --help display help message. -o FILENAME, --output=FILENAME write image to FILENAME. If '-' is specified, the result will be output to standard output. If -S is given, structured symbols are written to FILENAME-01.png, FILENAME-02.png, ... (suffix is removed from FILENAME, if specified) -r FILENAME, --read-from=FILENAME read input data from FILENAME. -s NUMBER, --size=NUMBER specify the size of dot (pixel). (default=3) -l {LMQH}, --level={LMQH} specify error correction level from L (lowest) to H (highest). (default=L) -v NUMBER, --symversion=NUMBER specify the minimum version of the symbol. See SYMBOL VERSIONS for more information. (default=auto) -m NUMBER, --margin=NUMBER specify the width of margin. (default=4) -d NUMBER, --dpi=NUMBER specify the DPI of the generated PNG. (default=72) -t {PNG,PNG32,EPS,SVG,XPM,ANSI,ANSI256,ASCII,ASCIIi,UTF8,UTF8i,ANSI- UTF8,ANSIUTF8i,ANSI256UTF8} --type={PNG,PNG32,EPS,SVG,XPM,ANSI,ANSI256,ASCII,ASCIIi,UTF8,UTF8i,AN- SIUTF8,ANSIUTF8i,ANSI256UTF8} specify the type of the generated image. (default=PNG) -S, --structured make structured symbols. Version number must be specified with '-v'. -k, --kanji assume that the input text contains kanji (shift-jis). -c, --casesensitive encode lower-case alphabet characters in 8-bit mode. (default) -i, --ignorecase ignore case distinctions and use only upper-case characters. -8, --8bit encode entire data in 8-bit mode. -k, -c and -i will be ignored. -M, --micro encode in a Micro QR Code. See MICRO QR CODE for more informa- tion. --rle enable run-length encoding for SVG. --svg-path use single path to draw modules for SVG. --inline only useful for SVG output, generates an SVG without the XML tag. --foreground=RRGGBB[AA] --background=RRGGBB[AA] specify foreground/background color in hexadecimal notation. 6-digit (RGB) or 8-digit (RGBA) form are supported. Color out- put support available only in PNG, EPS and SVG. --strict-version disable automatic version number adjustment. If the input data is too large for the specified version, the program exits with the code of 1. -V, --version display the version number and copyrights of the qrencode. --verbose display verbose information to stderr. [STRING] input data. If it is not specified, data will be taken from standard input. SYMBOL VERSIONS The symbol versions of QR Code range from Version 1 to Version 40. Each version has a different module configuration or number of modules, ranging from Version 1 (21 x 21 modules) up to Version 40 (177 x 177 modules). Each higher version number comprises 4 additional modules per side by default. See http://www.qrcode.com/en/about/version.html for a detailed version list. MICRO QR CODE With Micro QR Code, You can embed data in a smaller area than with QR Code, but the data capacity is strongly limited. The symbol versions range from Version 1 to 4. EXAMPLES qrencode -l L -v 1 -o output.png 'Hello, world!' encode into a symbol version 1, level L. qrencode -iSv 1 --output=output.png read standard input and encode it into a structured-appended symbols in case-insensitive mode. qrencode -S -v 40 -l L -r bigfile.txt -o output.png read input data from bigfile.txt and encode into a symbol ver- sion 40, level L.
