The PlayMetaFile function displays the picture stored in the given Windows-format metafile on the specified device.
Note This function is provided only for compatibility with Windows-format metafiles. Enhanced-format metafiles provide superior functionality and are recommended for new applications. The corresponding function for an enhanced-format metafile is PlayEnhMetaFile.

HMETAFILE hmf // handle to metafile
);

Remarks
To convert a Windows-format metafile into an enhanced format metafile, use the SetWinMetaFileBits function.
A Windows-format metafile can be played multiple times.
A Windows-format metafile can be embedded in a second Windows-format metafile by calling the PlayMetaFile function and playing the source metafile into the device context for the target metafile.
Any object created but not deleted in the Windows-format metafile is deleted by this function.
To stop this function, an application can call the CancelDC function from another thread to terminate the operation. In this case, the function returns FALSE.
