Method Detail

decode

public void decode()
            throws InvalidFileStructureException,
                   IOException
Description copied from class: TIFFDecoder
Decode data from input and write the decompressed pixel data to the image associated with this decoder. Child classes must override this method to implement the decoding for a particular compression type.

Specified by:
decode in class TIFFDecoder
Throws:
InvalidFileStructureException
IOException

getCompressionTypes

public Integer[] getCompressionTypes()
Description copied from class: TIFFDecoder
Returns an array with Integer values of all compression types supported by this decoder (see the COMPRESSION_xyz constants in TIFFConstants. Normally, this is only one value, but some compression types got assigned more than one constant (e.g. deflated). Also, a decoder could be capable of dealing with more than one type of compression if the compression types are similar enough to justify that. However, typically a decoder can only deal with one type of compression.

Specified by:
getCompressionTypes in class TIFFDecoder
Returns:
array with Integer objects of all TIFF compression constants supported by this decoder
