## 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

virtual 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

virtual 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.

virtual 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.

virtual 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.
