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. Reimplemented from EMF::METARECORD.

bool EMF::ENHMETAHEADER::serialize ( DATASTREAM ds ) [inline, virtual]

Serializing the header is an example of an extended record. Parameters: ds   metafile datastream. Reimplemented from EMF::METARECORD.

int EMF::ENHMETAHEADER::size ( void ) const [inline, virtual]

Internally computed size of this record. Reimplemented from EMF::METARECORD.

bool EMF::ENHMETAHEADER::unserialize ( DATASTREAM ds ) [inline]

Read a header record from the datastream.
