After the metafile header comes a series of metafile records that are used to build up an image on a device. Metafile records usually consist of the following:
struct {
DWORD rdSize;
WORD rdFunction;
WORD rdParm[];
}
Descriptions of these fields are detailed below:
|

Some metafile records have structures in the parameter field. They are called function-specific records, and are defined under the File Formats section of Volume 2 of the Microsoft Windows Programming Reference.
