public int getmMaxUncompressedByteCount()

decompressPlain

public byte[] decompressPlain(byte[] data,
                              int startOffset,
                              int width,
                              int count)

Decompress Plain. Returns the same data because it isn't compressed.

Parameters:

data - = data to decompress

startOffset - = data start offset

width - = data width

count - = data element count

Returns:

Decompressed data in all cases is the same data.

decompressTIFF

public byte[] decompressTIFF(byte[] data,
                             int startOffset,
                             int width,
                             int count)

Decompress Tiff. Returns decompressed Tiff data.

Parameters:

data - = data to decompress

startOffset - = data start offset

width - = data width

count - = data element count

Returns:

Decompressed data

decompressRL

public byte[] decompressRL(byte[] data,
                           int startOffset,
                           int width,
                           int count)

Returns decompressed Run Lenght data.

Parameters:

data - data to decompress

startOffset - data start offset

width - data width

count - data element count

Returns:

Decompressed data.

decompressDR

public byte[] decompressDR(byte[] data,
                           int startOffset,
                           int width,
                           int count)

Returns decompressed Delra Row data.

Parameters:

data - data to decompress
