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