GetEnhMetaFileBits function (wingdi.h)
The GetEnhMetaFileBits function retrieves the contents of the specified enhanced-format metafile and copies them into a buffer.
Syntax
UINT GetEnhMetaFileBits(
[in] HENHMETAFILE hEMF,
[in] UINT nSize,
[out] LPBYTE lpData
);
Parameters
[in] hEMF
A handle to the enhanced metafile.
[in] nSize
The size, in bytes, of the buffer to receive the data.
[out] lpData
A pointer to a buffer that receives 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 value
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.
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.
