* Invented by Denso Wave and described in the ISO/IEC 18004 standard.

* from 1 to 40, all 4 error correction levels, and 4 character encoding modes.
|
||||
*
|
||||
* Ways to create a QR Code object:
|
||||
* - High level: Take the payload data and call QrCode.encodeText() or QrCode.encodeBinary().
|
||||
* - Mid level: Custom-make the list of segments and call QrCode.encodeSegments().
|
||||
* - Low level: Custom-make the array of data codeword bytes (including
|
||||
* segment headers and final padding, excluding error correction codewords),
|
||||
* supply the appropriate version number, and call the QrCode() constructor.
|
||||
