| virtual E_TransferSyntax DJEncoderProgressive::supportedTransferSyntax | ( | ) | const [virtual] |
returns the transfer syntax that this particular codec is able to encode and decode.
Implements DJCodecEncoder.
| virtual OFBool DJEncoderProgressive::isLosslessProcess | ( | ) | const [private, virtual] |
returns true if the transfer syntax supported by this codec is lossless.
Implements DJCodecEncoder.
| virtual void DJEncoderProgressive::createDerivationDescription | ( | const DcmRepresentationParameter * | toRepParam, | |
| const DJCodecParameter * | cp, | |||
| Uint8 | bitsPerSample, | |||
| double | ratio, | |||
| OFString & | derivationDescription | |||
| ) | const [private, virtual] |
creates 'derivation description' string after encoding.
| toRepParam | representation parameter passed to encode() | |
| cp | codec parameter passed to encode() | |
| bitsPerSample | bits per sample of the original image data prior to compression | |
| ratio | image compression ratio. This is not the "quality factor" but the real effective ratio between compressed and uncompressed image, i. e. 30 means a 30:1 lossy compression. | |
| imageComments | image comments returned in this parameter which is initially empty |
Implements DJCodecEncoder.
| virtual DJEncoder* DJEncoderProgressive::createEncoderInstance | ( | const DcmRepresentationParameter * | toRepParam, | |
| const DJCodecParameter * | cp, | |||
| Uint8 | bitsPerSample | |||
| ) | const [private, virtual] |
creates an instance of the compression library to be used for encoding/decoding.
| toRepParam | representation parameter passed to encode() | |
| cp | codec parameter passed to encode() | |
| bitsPerSample | bits per sample for the image data |
Implements DJCodecEncoder.
