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

display help message.
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)
specify the size of dot (pixel). (default=3)
specify error collectin level from L (lowest) to H (highest). (default=L)
specify the version of the symbol. (default=auto)
specify the width of margin. (default=4)
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)
make structured symbols. Version must be specified.
assume that the input text contains kanji (shift-jis).
encode lower-case alphabet characters in 8-bit mode. (default)
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.
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.
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

encode into a symbol version 1, level L.
read standard input and encode it into a structured-appended symbols in case-insensitive mode.
