privatevirtual

creates an instance of the compression library to be used for decoding.

Parameters:

toRepParam	representation parameter passed to decode()
cp	codec parameter passed to decode()
bitsPerSample	bits per sample for the image data
isYBR	flag indicating whether DICOM photometric interpretation is YCbCr

Returns:: pointer to newly allocated decoder object

Implements DJCodecDecoder.

virtual E_TransferSyntax DJDecoderProgressive::supportedTransferSyntax ( ) const

virtual

returns the transfer syntax that this particular codec is able to encode and decode.

Returns:: supported transfer syntax

Implements DJCodecDecoder.
