    • Method Detail

      • 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

      • 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

      • 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

      • 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]
