PlayMetaFileRecord info  Overview  Group

The PlayMetaFileRecord function plays a Windows-format metafile record by executing the graphics device interface (GDI) function contained within that record.

This function is provided for compatibility with 16-bit versions of Microsoft Windows. Win32-based applications should use the PlayEnhMetaFileRecord function.

BOOL PlayMetaFileRecord(

    HDC hdc,

// handle to device context

    LPHANDLETABLE lpHandletable,

// pointer to metafile handle table

    LPMETARECORD lpMetaRecord,

// pointer to metafile record

    UINT nHandles 

// count of handles

   );

Parameters

hdc
Identifies a device context.
lpHandletable
Points to a table of handles identifying GDI objects used when playing the metafile.
lpMetaRecord
Points to the Windows-format metafile record.
nHandles
Specifies the number of handles in the handle table.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

A Windows-format metafile does not support the new curve, path, and transformation functions, such as PolyBezier, BeginPath, and SetWorldTransform. Applications that use these new functions and use metafiles to store pictures created by these functions, should use the enhanced format metafile functions.

To convert a Windows-format metafile into an enhanced-format metafile, use the SetWinMetaFileBits function.

An application typically uses PlayMetaFileRecord in conjunction with the EnumMetaFile function to process and play a Windows-format metafile one record at a time.

The lpHandletable and nHandles parameters must be identical to those passed to the EnumMetaFileProc callback procedure by EnumMetaFile.

If the PlayMetaFileRecord function does not recognize a record, it ignores the record and returns TRUE.
