java.lang.Object

com.archimed.dicom.converters.BaseFrameConverterOp

com.archimed.dicom.converters.NoopFrameConverterOp

All Implemented Interfaces:

FrameConverterOp

public class NoopFrameConverterOp
extends BaseFrameConverterOp

Default frame converter that does not do any transformation of the incoming frames but just echo's them untouched. This should work for all types of images both compressed and uncompressed and is the type of converter you would use to stream images to disk on a frame by frame basis.

Constructor Summary

Constructor and Description
NoopFrameConverterOp() creates a frame converter that does not perform any kind of frame conversion and does not change the transfer syntax
NoopFrameConverterOp(TransferSyntaxUID targetTransferSyntaxUID) creates a frame converter that does not perform any kind of frame conversion and outputs to the specified transfer syntax.

Constructor Detail

NoopFrameConverterOp

public NoopFrameConverterOp()

creates a frame converter that does not perform any kind of frame conversion and does not change the transfer syntax

NoopFrameConverterOp

public NoopFrameConverterOp(TransferSyntaxUID targetTransferSyntaxUID)

creates a frame converter that does not perform any kind of frame conversion and outputs to the specified transfer syntax. This must be one of the native transfer syntaxes ILE,ELE,EBE

Parameters:

targetTransferSyntaxUID - the target TransferSyntaxUID

Method Detail

canConvert

public boolean canConvert(DicomObject dcm)

This converter just echo's the incoming image. This method will return false when a specific native target transfer syntax is specified and the source transfer syntax is encapsulated or cannot be determined from the source file meta information.

Parameters:

dcm - the source DicomObject

Returns:

true or false

getConvertedTransferSyntax

public TransferSyntaxUID getConvertedTransferSyntax(DicomObject dcm)
                                             throws DicomException

returns the original transfer syntax from the original image based on the file meta information of the original image

Parameters:

dcm - the source DicomObject

Returns:

the transfer syntax UID of the converted DicomObject

Throws:

DicomException - -

convert

public byte[] convert(byte[] frame,
             ImageInfo imageInfo)

just returns the source frame. If necessary performs byte swapping of the frame data to convert from little endian to big endian or vice versa.

Parameters:

frame - the source pixel fame

imageInfo - relevant information of the image

Returns:

the converted pixel frame
