When I'm converting docx to pdf including wmf image, it's not display in output pdf

and I got error like:
08:21:29,587 ERROR [AWT-EventQueue-0] org.apache.fop.apps.FOUserAgent - Image not available. URI: file:///C:/Users/wiram/AppData/Local/Temp/image1.wmf. Reason: org.apache.xmlgraphics.image.loader.ImageException: The file format is not supported. No ImagePreloader found for file:///C:/Users/wiram/AppData/Local/Temp/image1.wmf (No context info available)
If any solution so pls, inform to me..
