Method Detail

decodeFrame

public abstract DicomPixelBuffer decodeFrame(DicomHeader header,
                                             DicomPixelData data)

Decode a frame given data

Parameters:

header - DICOM header

data - raw data from pixel data item

Returns:

decoded frame

decodeFrames

public boolean decodeFrames(DicomHeader header,
                            BinaryFileInputStream bin,
                            java.util.List<DicomPixelBuffer> frames)
                     throws java.io.IOException

Description copied from interface: DicomImageDecoder

Tries to decodes DICOM pixel data into a usable buffer, based on information contained in the DICOM header.

Specified by:

decodeFrames in interface DicomImageDecoder

Parameters:

header - informs the decoder of the transfer syntax, and any intensity transforms

bin - binary input stream of current file, at start of pixel data

frames - decoded pixel buffers (raw format) for frames

Returns:

true if decoder can and has successfully decoded frames, false if cannot. If false is returned, bin should be reset to the start of the pixel data.

Throws:

java.io.IOException - on File IO error
