GetEnhMetaFileBits info  Overview  Group

The GetEnhMetaFileBits function retrieves the contents of the specified enhanced-format metafile and copies them into a buffer.

UINT GetEnhMetaFileBits(

    HENHMETAFILE hemf,

// handle of metafile

    UINT cbBuffer,

// size of data buffer, in bytes

    LPBYTE lpbBuffer 

// address of data buffer

   );

Parameters

hemf
Identifies the enhanced metafile.
cbBuffer
Specifies the size, in bytes, of the buffer to receive the data.
lpbBuffer
Points to the buffer to receive the metafile data. The buffer must be sufficiently large to contain the data. If lpbBuffer is NULL, the function returns the size necessary to hold the data.

Return Values

If the function succeeds and the buffer pointer is NULL, the return value is the size of the enhanced metafile, in bytes.

If the function succeeds and the buffer pointer is a valid pointer, the return value is the number of bytes copied to the buffer.

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

Remarks

After the enhanced-metafile bits are retrieved, they can be used to create a memory-based metafile by calling the SetEnhMetaFileBits function.

The GetEnhMetaFileBits function does not invalidate the enhanced-metafile handle. The application must call the DeleteEnhMetaFile function to delete the handle when it is no longer needed.

The metafile contents retrieved by this function are in the enhanced format. To retrieve the metafile contents in the Windows format, use the GetWinMetaFileBits function.
