Method Detail

compress

public boolean compress(ShortBuffer buffer,
                        ByteBuffer compressed)

Description copied from interface: ICompressor

compress the buffer into the byte buffer. Attention enough space must already be allocated.

Specified by:

compress in interface ICompressor<ShortBuffer>

Parameters:

buffer - the buffer to compress.

compressed - the compressed data

Returns:

true if the compression succeeded.

decompress

public void decompress(ByteBuffer compressed,
                       ShortBuffer buffer)

Description copied from interface: ICompressor

Decompress the byte buffer and restore the buffer from it, again enough space must already be allocated.

Specified by:

decompress in interface ICompressor<ShortBuffer>

Parameters:

compressed - the compressed data

buffer - the buffer to fill with the uncompressed data.

nextPixel

protected int nextPixel()

Specified by:

nextPixel in class PLIOCompress

put

protected void put(int index,
                   int pixel)

Specified by:

put in class PLIOCompress
