Detailed Description

       Enhanced Metafile Header Record.

       The ENHMETAHEADER serves two purposes in this library: it keeps track of the size of the
       metafile (in physical dimensions) and number of records and handles that are ultimately to
       be written to the disk file. It is also a real record that must be written out.

Constructor & Destructor Documentation

   EMF::ENHMETAHEADER::ENHMETAHEADER (LPCWSTR description = 0) [inline]
       Parameters
           description an optional description argument is a UNICODE-like string with the
           following format: 'some text\0some more text\0\0'. The W32 interface defines UNICODE
           characters to be two-byte (unsigned short strings). The constructor makes a copy of
           the argument.

   EMF::ENHMETAHEADER::~ENHMETAHEADER () [inline]
       Destructor deletes memory allocated for description.

Member Function Documentation

   void EMF::ENHMETAHEADER::execute (METAFILEDEVICECONTEXT * source, HDC dc) const [inline],
       [virtual]
       Execute this record in the context of the given device context.

       Parameters
           source the device context from which this record is taken.
           dc device context for execute.

       Implements EMF::METARECORD.

   bool EMF::ENHMETAHEADER::serialize (DATASTREAM ds) [inline],  [virtual]
       Serializing the header is an example of an extended record.

       Parameters
           ds Metafile datastream.

       Implements EMF::METARECORD.

   int EMF::ENHMETAHEADER::size (void) const [inline],  [virtual]
       Internally computed size of this record.

       Implements EMF::METARECORD.

   bool EMF::ENHMETAHEADER::unserialize (DATASTREAM ds) [inline]
       Read a header record from the datastream.
