The input file can be an output of dcmdump (default indented format only). One element (tag, VR, value) must be written into one line separated by arbitrary spaces or tab characters. A '#' begins a comment that ends at the line end. Empty lines are allowed.

The individual parts of a line have the following syntax:

Tag:   (gggg,eeee)
       with gggg and eeee are 4 character hexadecimal values
       representing group and element tag.  Spaces and tabs can be
       anywhere in a tag specification.
VR:    Value Representation must be written as 2 characters as in
       Part 6 of the DICOM standard.  No spaces or tabs are allowed
       between the two characters.  If the VR can be determined from
       the tag, this part of a line is optional.
Value: There are several rules for writing values:
       1. US, SS, UL, SL, UV, SV, FD, FL, OD, OF, OL and OV are written
          as decimal strings that can be read by scanf().
       2. AT is written as '(gggg,eeee)' with additional spaces
          stripped off automatically and gggg and eeee being decimal
          strings that can be read by scanf().
       3. OB and OW values are written as byte or word hexadecimal
          values separated by '´ character.  Alternatively, OB or OW
          values can be read from a separate file by writing the
          filename prefixed by a '=' character (e.g. '=largepix.dat').
          The contents of the file will be read as is.  By default, OW
          data is expected to be little endian ordered and will be
          swapped if necessary.  No checks will be made to ensure that
          the amount of data is reasonable in terms of other attributes
          such as Rows or Columns.
          In case of compressed pixel data, the line should start with
          '(7fe0,0010) OB (PixelSequence' in order to distinguish from
          uncompressed pixel data.
       4. UI is written as '=Name' in data dictionary or as unique
          identifier string (see 6.), e.g. '[1.2.840.....]'.
       5. Strings without () <> [] spaces, tabs and # can be written
          directly.
       6. Other strings must be surrounded by '[' and ']'.  No bracket
          structure is passed.  The value ends at the last ']' in the
          line.  Anything after the ']' is interpreted as comment.
       7. '(' and '<' are interpreted special and may not be used when
          writing an input file by hand as beginning characters of a
          string.  Multiple Value are separated by '´.  The lines
          need not be sorted into ascending tag order.  References in
          DICOM Directories are not supported.  Semantic errors are
          not detected.

The following lines show valid examples of the syntax described above:

 (0008,0020) DA [19921012]            #  8, 1 StudyDate
 (0008,0016) UI =MRImageStorage       # 26, 1 SOPClassUID
 (0002,0012) UI [1.2.276.0.7230010.100.1.1]
 (0020,0032) DS [0.0 .0]             #  8, 2 ImagePositionPatient
 (0028,0009) AT (3004,000c)           #  4, 1 FrameIncrementPointer
 (0028,0010) US 256                   #  4, 1 Rows
 (0002,0001) OB 01 0

Please note that dump2dcm currently does not fully support DICOMDIR files. Specifically, the value of the various offset data elements is not updated automatically by this tool.
