qrencode_raw(to_encode, version = 0L, level = 0L, hint = 2L,

Arguments

to_encode

character string to encode

version

version of the symbol. If 0, the library chooses the minimum version for the given input data.

level

error correction level (0 - 3, lowest to highest)

hint

tell the library how Japanese Kanji characters should be encoded. If "3", the library assumes that the given string contains Shift-JIS characters and encodes them in Kanji-mode. If "2" is given, all of non-alphanumerical characters will be encoded as is. If you want to embed UTF-8 string, choose this. Other mode will cause EINVAL error.

"0" is "numeric mode", "1" is "alphanumeric mode", "5" is "ECI mode".

caseinsensitive

case-sensitive(1) or not(0).
