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 *	,
		HDC
	)		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.
