Examples of java.util.zip.Deflater.deflate()

java.util.zip.Deflater.deflate()
Fills specified buffer with compressed data. Returns actual number of bytes of compressed data. A return value of 0 indicates that needsInput() should be called in order to determine if more input data is required. @param b the buffer for the compressed data @param off the start offset of the data @param len the maximum number of bytes of compressed data @return the actual number of bytes of compressed data

      // give it to compressor 
      defl.setInput(rowBuffer);
      // store compressed data in outBuffer 
      do
      {
        numDeflated = defl.deflate(outBuffer, outOffset, outBuffer.length - outOffset);
        outOffset += numDeflated;
        if (outOffset == outBuffer.length)
        {
          saveChunk(CHUNK_TYPE_IDAT,  outOffset, outBuffer);
          outOffset = 0;
