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.
