3.2 Typical Metafile Record

The graphics device interface stores most of the GDI functions that an application can use to create metafiles in typical records.

A typical metafile record has the following form:

struct {
    DWORD rdSize;
    WORD  rdFunction;
    WORD  rdParm[];
}

Following are the members in a typical metafile record:

rdSize

Specifies the size, in words, of the record.

rdFunction

Specifies the function number. This value may be the number of any function in the table at the end of this section.

rdParm

Identifies an array of words containing the function parameters (listed in the reverse order in which they are passed to the function).

Following are the GDI functions found in typical records, along with their hexadecimal values:

For more information on GDI functions, see the Microsoft Windows Programmer's Reference, Volume 2. For more information on the function-specific metafile records, see Section 3.6, “Function-Specific Metafile Records.”
