GetMetaFileBitsEx
The GetMetaFileBitsEx function retrieves the contents of a Windows-format metafile and copies them
into the specified buffer.
This function is provided for compatibility with earlier versions of Microsoft
Windows. Win32-based applications should use the GetEnhMetaFileBits function.
UINT GetMetaFileBitsEx(
HMETAFILE hmf,
| // handle of metafile
| UINT nSize,
| // size of metafile, in bytes
| LPVOID lpvData
| // address of metafile data
| );
|
|
Parameters
hmf
Identifies a Windows-format metafile.
nSize
Specifies the size, in bytes, of the buffer to receive the data.
lpvData
Points to the buffer to receive the metafile data. The buffer must be
sufficiently large to contain the data. If lpvData is NULL, the function returns the number of bytes required to hold the data.
Return Values
If the function succeeds and the buffer pointer is NULL, the return value is
the number of bytes required for the buffer; if the function succeeds and the
buffer pointer is a valid pointer, the return value is the number of bytes
copied.
If the function fails, the return value is zero.
Remarks
After the Windows-metafile bits are retrieved, they can be used to create a
memory-based metafile by calling the SetMetaFileBitsEx function.
The GetMetaFileBitsEx function does not invalidate the metafile handle. An application must delete
this handle by calling the DeleteMetaFile function.
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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
