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.
