private void writeFileHeader()
throws java.io.IOException
writeDirectory
private void writeDirectory(int thisIFDOffset,
java.util.SortedSet fields,
int nextIFDOffset)
throws java.io.IOException

writeLong
private void writeLong(long l)
throws java.io.IOException
getOffset
private long getOffset(java.io.OutputStream out)
throws java.io.IOException
- Returns the current offset in the supplied OutputStream.
This method should only be used if compressing data.
compressPackBits
private static int compressPackBits(byte[] data,
int numRows,
int bytesPerRow,
byte[] compData)
- Performs PackBits compression on a tile of data.
packBits

- Performs PackBits compression for a single buffer of data.
This should be called for each row of each tile. The returned
value is the offset into the output buffer after compression.

byte[] inflated,
byte[] deflated)
modifyEncodeParam
private static void modifyEncodeParam(com.sun.image.codec.jpeg.JPEGEncodeParam src,
