PDFBox and Batik SVGGraphics2d

[Rich Stafford]

I am having an issue using PDFBox (pdfbox-app-2.0.21.jar) and SVGGraphics2d 
(batik-1ll-1.16.jar) to generate SVG output from a small PDF file.

This file has about 9 vector lines, and a rectangle filled with horizontal 
lines.  Using the PDFBox PDFRenderer to JPG, I get the appropriate fill for the 
rectangle:

However, using the PDFBox PDFRenderer with SVGGraphics2d, I get a black filled 
rectangle.

The generator code fragment is as follows:

// setup instance of org.w3c.dom.Document
DOMImplementation oDom = GenericDOMImplementation.getDOMImplementation();
String sSvgOrg = "http://www.w3.org/2000/svg";;
Document oSvgDoc = oDom.createDocument(sSvgOrg, "svg", null);
SVGGeneratorContext oCtx = SVGGeneratorContext.createDefault(oSvgDoc);
oCtx.setEmbeddedFontsOn(true);

// setup renderer object
PDFRenderer oRender = new PDFRenderer( oDoc );

// loop for all pages in the PDF
for ( int nPageNdx = 0; nPageNdx < oDoc.getNumberOfPages(); nPageNdx++ )
{
        // setup output file
        if ( sOutputMode.equalsIgnoreCase("svg") )
        {       // svg
                String sSvgPageSpec = GenericUtil.PathMake(sDestPath, 
"page-"+nPageNdx+".svg");
                (new File(sSvgPageSpec)).createNewFile();
                // setup instance of SVG Generator
                SVGGraphics2D oSvgGen = new SVGGraphics2D( oCtx, false );
                // render the page to SVG
                oRender.renderPageToGraphics( nPageNdx, oSvgGen );
                // write to file
                OutputStream oOutStream = new FileOutputStream( new 
File(sSvgPageSpec) );
                Writer oOutWriter = new OutputStreamWriter( oOutStream, "UTF-8" 
);
                oSvgGen.stream( oOutWriter, true );
                continue;
        }
        if ( sOutputMode.equalsIgnoreCase("jpg") )
        {       // jpg output
                String sJpgPageSpec = GenericUtil.PathMake(sDestPath, 
"page-"+nPageNdx+".jpg");
                File oFileJpg = new File(sJpgPageSpec);
                BufferedImage image = oRender.renderImageWithDPI(nPageNdx, 
GenericUtil.parseInt(sDpi, 300));
                ImageIO.write(image, "JPEG", oFileJpg);
                continue;
        }
}

I've attached the input PDF file as well.

Thoughts?
