Convert EMF + file (not WMF / EMF) to PNG in java

Question

Convert EMF + file (not WMF / EMF) to PNG in java

Problem:

I have an image of an extended Extat Plus EMF + metafile extension . I need to convert this file to a PNG image file using java.

Attempts to solve the problem in java:

Apache Batikdoes not support EMF + format (Batik only supports WMF format ).
FreeHEPdoes not support EMF + . It can convert EMF to SVG and then SVG to PNG . I was hoping this would help:
```
EMF2SVG.main( new String[] {inputMetaFileName,ontputSvgFileName});
```
this statement should convert EMF to SVG , but gives an exception:
java.lang. exportchooser.AbstractExportFileType.exportToFile (AbstractExportFileType.java:282) at org.freehep.graphicsio.emf.EMFConverter.export (EMFConverter.java:81) at org.freehep.graphicsio.emf.EMF2SVG.main (EMF2VV)

I used the code here :

try {
    // read the EMF file
    EMFRenderer emfRenderer = new EMFRenderer( new EMFInputStream(
        new ByteArrayInputStream(emfBytes)));

    EMFPanel emfPanel = new EMFPanel();
    emfPanel.setRenderer(emfRenderer);

    // prepare Graphics2D
    FileOutputStream svg = new FileOutputStream("svg.svg");
    SVGGraphics2D graphics2D = new SVGGraphics2D (svg, emfPanel);

    // export to SVG
    graphics2D.startExport();
    emfPanel.print(graphics2D);
    graphics2D.endExport();
    svg.flush();
    svg.close();
} catch (IOException e) {
    e.printStackTrace();
}
