Re: PDFBox and Batik SVGGraphics2d

[Tilman Hausherr]

Hi,

I can confirm the effect with my own conversion code (which may or may 
not be the same). I looked at the SVG and there's one thing missing: 
PDFBox converts patterns to bitmaps and then uses TexturePaint. So there 
should be some binary content in the SVG but there isn't. Could it be 
that there is some option that should be set?

Btw the PDF has some errors, like 0 255 0 sc  (or rg), this should be 0 
1 0 sc (or rg). But this isn't the cause.

Thanks for your quick response.  I've upgraded to PDFBox 2.0.27, with 
the same results.

The PDF file can be downloaded here:

for any assistance.  I'm going to start tracing thru Batik source code 
for the SVG error.

Hi,

Please try with 2.0.27 and upload the PDF somewhere, it didn't get 
through.

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?
