Tool to convert PDF to PDF/DICOM.

## SYNOPSIS

    gdcmpdf [options] file-in file-out

## DESCRIPTION

The gdcmpdf tool convert a PDF file (any PDF version) into an encapsulated PDF/DICOM file. 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.

## PARAMETERS

    file-in   PDF input filename

    file-out  DICOM output filename

## options

### general options

      -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

## Usage Example

    $ 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

## PDF Info Mapping

Here is how the PDF info is mapped to DICOM information (typical pdfinfo output):

Explanation for the different Date/Time mappings:

- Study Date/Time, Instance Creation Date/Time are both equal to the current time gdcmpdf tool was run,
- Acquisition Date Time is set to the Modify Time of the actual pdf file,
- Content Date/Time are set from the actual PDF header info: CreationDate.
