C# Signature:
[DllImport("gdi32.dll")]
static extern IntPtr CopyEnhMetaFile(IntPtr hemfSrc, string lpszFile);
User-Defined Types:
None.
Notes:
Please note that this API method needs to be called twice! 1st to get the size of the enh meta file and 2nd to fill the buffer.
Tips & Tricks:
Please add some!
Sample Code:
public static byte[] GetEnhMetaFileBits(Metafile mf)
{
ResetLastError();
uint bufferSize = GetEnhMetaFileBits(mf.GetHenhmetafile(), 0, null); // Get required buffer size specifying 0 and NULL.
if (bufferSize == 0)
{
int lastError = Marshal.GetLastWin32Error();
throw new Exception("GetEnhMetaFileBits failed.", new Win32Exception(lastError));
}
byte[] buffer = new byte[bufferSize];
if (GetEnhMetaFileBits(mf.GetHenhmetafile(), bufferSize, buffer) == 0) // Get raw metafile data.
{
int lastError = Marshal.GetLastWin32Error();
throw new Exception("GetEnhMetaFileBits failed.", new Win32Exception(lastError));
}
return buffer;
}
[DllImport("gdi32.dll", EntryPoint = "CopyEnhMetaFile", SetLastError = true, CharSet = CharSet.Auto)]
