NAME¶
qrencode - Encode input data in a QR Code and save as a PNG or EPS image.
SYNOPSIS¶
qrencode [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)
- -s NUMBER, --size=NUMBER
- specify the size of dot (pixel). (default=3)
- -l {LMQH}, --level={LMQH}
- specify error collectin level from L (lowest) to H (highest). (default=L)
- -v NUMBER, --symversion=NUMBER
- specify the version of the symbol. (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,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8,ANSIUTF8}
- --type={PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8,ANSIUTF8}
- specify the type of the generated image. (default=PNG)
- -S, --structured
- make structured symbols. Version must be specified.
- -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. (experimental)
- --foreground=RRGGBB[AA]
- --background=RRGGBB[AA]
- specify foreground/background color in hexadecimal notation. 6-digit (RGB) or 8-digit (RGBA) form are supported. Color output support available only in PNG and SVG.
- -V, --version
- display the version number and copyrights of the qrencode.
- [STRING]
- input data. If it is not specified, data will be taken from standard input.
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.
