 com.sun.media.imageioimpl.common.LZWCompressor
| LZWCompressor | | public class LZWCompressor (Code) | | Modified from original LZWCompressor to change interface to passing a
buffer of data to be compressed.
|
| Method Summary | |
| public void | compress(byte[] buf, int offset, int length)
| | public void | dump(PrintStream out)
| | public void | flush()
Indicate to compressor that no more data to go so write out
any remaining buffered data. |
| clearCode_ | | int clearCode_(Code) | | reserved clear code based on code size *
|
| codeSize_ | | int codeSize_(Code) | | base underlying code size of data being compressed 8 for TIFF, 1 to 8 for GIF *
|
| endOfInfo_ | | int endOfInfo_(Code) | | reserved end of data code based on code size *
|
| limit_ | | int limit_(Code) | | limit at which current number of bits code size has to be increased *
|
| numBits_ | | int numBits_(Code) | | current number bits output for each code *
|
| prefix_ | | short prefix_(Code) | | the prefix code which represents the predecessor string to current input point *
|
| tiffFudge_ | | boolean tiffFudge_(Code) | | modify the limits of the code values in LZW encoding due to TIFF bug / feature *
|
| LZWCompressor | | public LZWCompressor(ImageOutputStream out, int codeSize, boolean TIFF) throws IOException(Code) | |
Parameters:
out - destination for compressed data
Parameters:
codeSize - the initial code size for the LZW compressor
Parameters:
TIFF - flag indicating that TIFF lzw fudge needs to be applied
exception:
IOException - if underlying output stream error |
| compress | | public void compress(byte[] buf, int offset, int length) throws IOException(Code) | |
Parameters:
buf - data to be compressed to output stream
exception:
IOException - if underlying output stream error |
| flush | | public void flush() throws IOException(Code) | | Indicate to compressor that no more data to go so write out
any remaining buffered data.
exception:
IOException - if underlying output stream error |
