black images when using ChangeFromEmf method

In my printer_EmfEvent, using the ChangeFromEmf method generates solid black pages. I know the metafile object is good, because the GDI code works. What am I doing wrong?

void printer_EmfEvent(object sender, Leadtools.Printer.EmfEventArgs e)
{
var metafile = new System.Drawing.Imaging.Metafile(e.Stream);

// the file produced by this code is a valid image.
using (var bmp = new System.Drawing.Bitmap(metafile.Width, metafile.Height))
{
bmp.SetResolution(metafile.HorizontalResolution, metafile.VerticalResolution);
using (var g = System.Drawing.Graphics.FromImage(bmp))
{
g.Clear(Color.White);
g.DrawImage(metafile, 0, 0, bmp.Width, bmp.Height);
bmp.Save(@"c:\temp\gdiplus.tif", System.Drawing.Imaging.ImageFormat.Tiff);
}
}

// the file produced by this code is a solid black image.
IntPtr hemf = metafile.GetHenhmetafile();
using (var image = Leadtools.Drawing.RasterImageConverter.ChangeFromEmf(hemf, 0, 0))
{
codecs.Save(image, @"c:\temp\lead.tif", Leadtools.RasterImageFormat.Tif, 32);
}
}

The black you are seeing is the transparency of the emf stream. When sending print calls most document files will often send a transparent background to the emf. You're workaround is fine however we can load the emf directly with no issue.

This code is all it takes to do so:

RasterImage m_myImage = m_Codecs.Load( e.Stream );

When you save this image out it will have the proper background. ChangeFromEmf does not fill background data it merely takes the data in the emf directly out. Transparency is just interpreted as black.

You can refer to my sample for rerouting printers in a window service, as it is done in this manner there.
