Class MicroQrCodeEncoder

java.lang.Object
boofcv.alg.fiducial.microqr.MicroQrCodeEncoder
All Implemented Interfaces:
VerbosePrint
public class MicroQrCodeEncoder extends Object implements VerbosePrint
Provides an easy to use interface for specifying QR-Code parameters and generating the raw data sequence. After the QR Code has been created using this class it can then be rendered. By default it will select the qr code version based on the number of bits and the error correction level based on the version and number of bits. If the error correction isn't specified and the version isn't specified then error correction level M is used by default.

  • Method Details

    • reset

      public void reset()

    • setVersion

      public MicroQrCodeEncoder setVersion(int version)

    • setError

      Returns:
      The QR-Code

    • addNumeric

      public MicroQrCodeEncoder addNumeric(byte[] numbers)
      Creates a QR-Code which encodes a number sequence
      Parameters:
      numbers - Array of numbers. Each number has to be from 0 to 9 inclusive.
      Returns:
      The QR-Code

      public MicroQrCodeEncoder addAlphanumeric(String alphaNumeric)
      Creates a QR-Code which encodes data in the alphanumeric format
      Parameters:
      alphaNumeric - String containing only alphanumeric values.
      Returns:
      The QR-Code

    • addBytes

      public MicroQrCodeEncoder addBytes(String message)

    • addBytes

      public MicroQrCodeEncoder addBytes(byte[] data)
      Creates a QR-Code which encodes data in the byte format.
      Parameters:
      data - Data to be encoded
      Returns:
      The QR-Code

    • addKanji

      public MicroQrCodeEncoder addKanji(String message)
      Creates a QR-Code which encodes Kanji characters
      Parameters:
      message - Data to be encoded
      Returns:
      The QR-Code

    • fixate

      public MicroQrCode fixate()
      Call this function after you are done adding to the QR code
      Returns:
      The generated QR Code
