qrencode: Encode input data in a QR Code and save as a PNG image.


qrencode - Encode input data in a QR Code and save as a PNG image.


qrencode [OPTION]... [STRING]


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 image.
-h, --help display help message. -o FILENAME, --output=FILENAME write PNG image to FILENAME. If '-' is specified, the result will be output to standard output. -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) -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. -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.
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.
