By default it will try to read the PDF meta information stored in the PDF and convert this information to some specific DICOM fields (see below). However it may fails (eg. wrong password on encrypted PDF file) in which case empty value are used. file-in PDF input filename file-out DICOM output filename -h --help print this help text and exit -v --version print version information and exit -V --verbose verbose mode (warning+error). -W --warning warning mode, print warning information -E --error error mode, print error information -D --debug debug mode, print debug information $ wget http://gdcm.sourceforge.net/gdcm.pdf $ gdcmpdf gdcm.pdf gdcm.dcm To re-extract the encapsulated PDF file: $ gdcmraw -i gdcm.dcm -t 42,11 -o gdcm.dcm.pdf $ diff gdcm.pdf gdcm.dcm.pdf Here is how the PDF info is mapped to DICOM information (typical pdfinfo output): Title: GDCM Reference Manual Subject: Grassroots DICOM API reference Keywords: GDCM,DICOM,JPEG,Lossless JPEG,JPEG-LS,J2K,JPEG 2000,RLE Author: Mathieu Malaterre and co.
