Constructor Detail

TIFFFaxCompressor	back to summary
protected TIFFFaxCompressor(String compressionType, int compressionTagValue, boolean isCompressionLossless) Constructor. The superclass constructor is merely invoked with the same parameters.

Method Detail

add1DBits	back to summary
public int add1DBits(byte[] buf, int where, int count, int color) Get code for run and add to compressed bitstream.

add2DBits	back to summary
public int add2DBits(byte[] buf, int where, int[][] mode, int entry) Place entry from mode table into compressed bitstream.

addEOFB	back to summary
public int addEOFB(byte[] buf, int where) Add an End-of-Facsimile-Block (EOFB == 0x001001) to the compressed bitstream.

addEOL	back to summary
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.

encode1D	back to summary
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.

encode1D

back to summary

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.

initBitBuf	back to summary
public void initBitBuf() Initialize bit buffer machinery.

nextState	back to summary
public int nextState(byte[] data, int base, int bitOffset, int maxOffset) Return min of `maxOffset` or offset of first pixel different from pixel at `bitOffset`.

setMetadata back to summary

public void setMetadata(IIOMetadata metadata)

Overrides com.sun.imageio.plugins.tiff.TIFFCompressor.setMetadata.

Sets the value of the metadata field.

The implementation in this class also sets local options from the FILL_ORDER field if it exists.

Parameters
