The default conversion mode for WMF and EMF images is to use Windows to render these into a bitmapped image, and the bitmapped image is then included in the PDF. This is the most compatible conversion as the PDF contains a 100% accurate rendition of the WMF or EMF image. The downside to this is that this can create a large PDF file and a high quality vector image has been turned into a non-scalable bitmapped image. However, there is also an option to convert WMF or EMF images into a native PDF commands, this is where graphic commands in WMF/EMF are turned into their equivalent PDF graphic commands. This gives much better quality (keeping the image within the PDF scalable too) and a smaller PDF size too. However, it is not possible to convert all possible WMF and EMF image commands into native PDF equivalent commands so the conversion may not be 100% accurate.
