Detailed Description

The base class of all metafile records.

A metafile consists off a sequence of graphics records "executed" in order. This is a common base class that allows each, different, record to be stored in a common list. An interface is specified for each record to write itself to a file.

Constructor & Destructor Documentation

EMF::METARECORD::~METARECORD ( ) [inline, virtual]

The virtual destructor allows records which allocated additional memory to release it when they are deleted. Simple records just use the default destructor defined here.

Member Function Documentation

void EMF::METARECORD::execute ( METAFILEDEVICECONTEXT * source, HDC dc ) const [pure virtual]

Execute the graphics command in the given context. Used by PlayEnhMetaFile to "copy" one metafile into another. Parameters: source   the device context from which this record is taken. dc   the destination context.

bool EMF::METARECORD::serialize ( DATASTREAM ds ) [pure virtual]

Write yourself to the given file. This is virtual since some records are of arbitrary length and need to write additional information after their EMR structure. Parameters: ds   the datastream to write oneself to.

int EMF::METARECORD::size ( void ) const [pure virtual]

The header record of a metafile records the total size of the metafile in bytes, so as each record is added to the list, it updates the total size.
