Currently EMF and WMF images work with graphics using their own Graphics classes. I have shared the example how to convert provided files.
using (var image = Aspose.Imaging.Image.Load("chart.emf"))
{
EmfRecorderGraphics2D emfGraphics = EmfRecorderGraphics2D.FromEmfImage((EmfImage)image);
// create an instance of Font. Initialize it with Font Face, Size and Style
var font = new Aspose.Imaging.Font("Arial", 20, Aspose.Imaging.FontStyle.Bold);
emfGraphics.DrawString("CONFIDENTIAL", font, Color.Red, 100, 100);
EmfImage im2 = emfGraphics.EndRecording();
im2.Save("output.emf");
}
using (var image = Aspose.Imaging.Image.Load("lantern.wmf"))
{
WmfRecorderGraphics2D emfGraphics = WmfRecorderGraphics2D.FromWmfImage((WmfImage)image);
// create an instance of Font. Initialize it with Font Face, Size and Style
var font = new Aspose.Imaging.Font("Arial", 20, Aspose.Imaging.FontStyle.Bold);
emfGraphics.DrawString("CONFIDENTIAL", font, Color.Red, 100, 100);
WmfImage im2 = emfGraphics.EndRecording();
im2.Save("output.wmf");
}
