EMF::ENHMETAHEADER - Enhanced Metafile Header Record.
Contents
Constructor & Destructor Documentation
EMF::ENHMETAHEADER::ENHMETAHEADER(LPCWSTRdescription=0)[inline]Parametersdescription 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.
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.
