Constructor. |
| Method Summary | |
| public int | add1DBits(byte[] buf, int where, int count, int color)
Get code for run and add to compressed bitstream. | | public int | add2DBits(byte[] buf, int where, int[][] mode, int entry)
Place entry from mode table into compressed bitstream. | | public int | addEOFB(byte[] buf, int where)
Add an End-of-Facsimile-Block (EOFB == 0x001001) to the compressed
bitstream. | | 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. | | public int | encode1D(byte[] data, int rowOffset, int colOffset, int rowLength, byte[] compData, int compOffset)

|
| TIFFFaxCompressor | | protected TIFFFaxCompressor(String compressionType, int compressionTagValue, boolean isCompressionLossless)(Code) | | Constructor. The superclass constructor is merely invoked with the
same parameters.
|
| add1DBits | | public int add1DBits(byte[] buf, int where, int count, int color)(Code) | | Get code for run and add to compressed bitstream.
|
| add2DBits | | public int add2DBits(byte[] buf, int where, int[][] mode, int entry)(Code) | | Place entry from mode table into compressed bitstream.
|
| addEOFB | | public int addEOFB(byte[] buf, int where)(Code) | | Add an End-of-Facsimile-Block (EOFB == 0x001001) to the compressed
bitstream.
|
| addEOL | | public int addEOL(boolean is1DMode, boolean addFill, boolean add1, byte[] buf, int where)(Code) | | Add an End-of-Line (EOL == 0x001) to the compressed bitstream
with optional byte alignment.
|
| encode1D | | public int encode1D(byte[] data, int rowOffset, int colOffset, int rowLength, byte[] compData, int compOffset)(Code) | | 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 | | public void initBitBuf()(Code) | | Initialize bit buffer machinery.
|
| nextState | | public int nextState(byte[] data, int base, int bitOffset, int maxOffset)(Code) | | Return min of maxOffset or offset of first pixel
different from pixel at bitOffset.
|
| setMetadata | | public void setMetadata(IIOMetadata metadata)(Code) | | 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:
metadata - the IIOMetadata object for theimage being written.
