Examples with ReedSolomonEncoder com.google.zxing.common.reedsolomon.ReedSolomonEncoder used on opensource projects

Example 1 with ReedSolomonEncoder

use of com.google.zxing.common.reedsolomon.ReedSolomonEncoder in project weex-example by KalicyZhou.

the class Encoder method generateCheckWords.

private static BitArray generateCheckWords(BitArray bitArray, int totalBits, int wordSize) {
    // bitArray is guaranteed to be a multiple of the wordSize, so no padding needed
    int messageSizeInWords = bitArray.getSize() / wordSize;
    ReedSolomonEncoder rs = new ReedSolomonEncoder(getGF(wordSize));
    int totalWords = totalBits / wordSize;
    int[] messageWords = bitsToWords(bitArray, wordSize, totalWords);
    rs.encode(messageWords, totalWords - messageSizeInWords);
    int startPad = totalBits % wordSize;
    BitArray messageBits = new BitArray();
    messageBits.appendBits(0, startPad);
    for (int messageWord : messageWords) {
        messageBits.appendBits(messageWord, wordSize);
    }
    return messageBits;
}

Example 2 with ReedSolomonEncoder

use of com.google.zxing.common.reedsolomon.ReedSolomonEncoder in project weex-example by KalicyZhou.

the class Encoder method generateECBytes.

    int numDataBytes = dataBytes.length;
    int[] toEncode = new int[numDataBytes + numEcBytesInBlock];
