List of codeone() Examples

Examples of codeone()

com.nr.lna.Arithcode.codeone()
com.nr.lna.Huffcode.codeone()
Huffman encode the single character ich (in the range 0..nch-1), write the result to the byte array code starting at bit nb (whose smallest valid value is zero), and increment nb to the first unused bit. This routine is called repeatedly to encode consecutive characters in a message. The user is responsible for monitoring that the value of nb does not overrun the length of code. @param ich @param code @param nb

Examples of com.nr.lna.Arithcode.codeone()

    // Test codeone
    Arithcode arith = new Arithcode (nfreq,NCHAR,256);
    arith.messageinit();
    lcd.val=0;
    byte[] code = new byte[N];
    for (i=0;i<N;i++) arith.codeone(c[i],code,lcd);
    arith.codeone(NCHAR,code,lcd);    // EOM character
//    System.out.println("Number of bytes used: %f\n", lcd);
//    System.out.println("Compression ratio: %f\n", double(N*3)/8/lcd); // Normally 3 bits each for 5 characters


    // Recover the text
