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
descriptionan 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.
