PdfProcessing: Add support for WMF/EMF images

Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:

ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));

document.Pages.AddPage().Content.AddImage(imageSource);

...

private byte[] ConvertWmfImageToPng(Stream wmfImageStream)

{

byte[] pngBytes;

using (MemoryStream pngImageStream = new MemoryStream())

{

System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);

imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);

pngBytes = pngImageStream.ToArray();

}

return pngBytes;

}
