Method Detail

doSomethingWithDicomFileOnMedia

protected void doSomethingWithDicomFileOnMedia(java.lang.String mediaFileName)

Compress the DICOM file.

Overrides:

doSomethingWithDicomFileOnMedia in class MediaImporter

Parameters:

mediaFileName - the fully qualified path name to a DICOM file

doSomethingWithUnwantedFileOnMedia

protected void doSomethingWithUnwantedFileOnMedia(java.lang.String mediaFileName,
                                                  java.lang.String transferSyntaxUID,
                                                  java.lang.String sopClassUID)

Log that file cannot be compressed.

A subclass could do something more creative, like copy the file to a new file without recompressing it to make sure the set of files remains complete.

Overrides:

doSomethingWithUnwantedFileOnMedia in class MediaImporter

Parameters:

mediaFileName - the fully qualified path name to a DICOM file

transferSyntaxUID - the Transfer Syntax of the Data Set if a DICOM file, from the DICOMDIR or Meta Information Header

sopClassUID - the SOP Class of the Data Set if a DICOM file, from the DICOMDIR or Meta Information Header

isOKToImport

protected boolean isOKToImport(java.lang.String sopClassUID,
                               java.lang.String transferSyntaxUID)

Is the DICOM file OK to compress?

Overrides:

isOKToImport in class MediaImporter

Parameters:

sopClassUID - the SOP Class UID of the file

transferSyntaxUID - the Transfer Syntax UID of the file

Returns:

true if is suitable

main

public static void main(java.lang.String[] arg)

Copy a set of DICOM image files, compressing them losslessly with JPEG 2000 (default), JPEG 10918-1 Lossless Huffman SV1, JPEG-LS or RLE.

Non-image files are ignored (not copied).

Parameters:

arg - array of two or three strings - the input path and the output path and optionally the requested compressed transfer syntax [1.2.840.10008.1.2.4.90|1.2.840.10008.1.2.4.70|1.2.840.10008.1.2.4.80|1.2.840.10008.1.2.5] or output format string [jpeg2000|jpeg-lossless|jpeg-ls|rle]
