- Method Detail
  - setMetadata
```
public void setMetadata(javax.imageio.metadata.IIOMetadata metadata)

    Overrides:
    
    setMetadata in class TIFFCompressor
    
    Parameters:
    
    metadata - the IIOMetadata object for the image being written.
    
    See Also:
    
    TIFFCompressor.getMetadata()
  - nextState

  - initBitBuf
```
public void initBitBuf()
```
    Initialize bit buffer machinery.
  - add1DBits
```
public int add1DBits(byte[] buf,
                     int where,
                     int count,
                     int color)
```
    Get code for run and add to compressed bitstream.
  - add2DBits
```
public int add2DBits(byte[] buf,
                     int where,
                     int[][] mode,
                     int entry)
```
    Place entry from mode table into compressed bitstream.
  - addEOL
```
public int addEOL(boolean is1DMode,
                  boolean addFill,
                  boolean add1,
                  byte[] buf,
                  int where)
```
    Add an End-of-Line (EOL == 0x001) to the compressed bitstream with optional byte alignment.
  - addEOFB
```
public int addEOFB(byte[] buf,
                   int where)
```
    Add an End-of-Facsimile-Block (EOFB == 0x001001) to the compressed bitstream.
  - encode1D
```
public int encode1D(byte[] data,
                    int rowOffset,
                    int colOffset,
                    int rowLength,
                    byte[] compData,
                    int compOffset)
```
    One-dimensionally encode a row of data using CCITT Huffman compression. The bit buffer should be initialized as required before invoking this method and should be flushed after the method returns. The fill order is always highest-order to lowest-order bit so the calling routine should handle bit inversion.
