      Description

      An SVG file using markers is not rendered by FOP 2.0

      How to reproduce the problem (see attached files)

      fop -fo __doc.fo -pdf __doc.pdf

      Running this command reports:

      SEVERE: SVG graphic could not be built. Reason: org.apache.batik.bridge.BridgeException: resources/resources/header_layout.svg (No such file or directory)

      The expected result is EXPECTED__doc.pdf

      My workaround:

      To resolve URLs such as "marker-start:url(#TriangleInM)", Batik 1.8 needs
      to know the URL of the SVG document it processes.

      Therefore in org/apache/fop/apps/FOUserAgent.java, I've replaced:

          public StreamSource resolveURI(String uri) {
              // TODO: What do we want to do when resources aren't found??? We also need to remove this
              // method entirely
              try {
                  // Have to do this so we can resolve data URIs
                  StreamSource src = new StreamSource(resourceResolver.getResource(uri));
                  src.setSystemId(uri);
                  return src;
              } catch (URISyntaxException use) {
                  return null;
              } catch (IOException ioe) {
                  return null;
              }
          }
      

      by:

          public StreamSource resolveURI(String uri) {
              // TODO: What do we want to do when resources aren't found??? We also need to remove this
              // method entirely
              try {
                  // Have to do this so we can resolve data URIs
                  StreamSource src = new StreamSource(resourceResolver.getResource(uri));
      
                  // A systemId is always expected to be absolute.
                  // Anyway, without this, SVG files using markers 
                  // (e.g. marker-start:url(#TriangleInM)) cannot be rendered.
      
                  if (!uri.startsWith("data:")) {
                      uri = resourceResolver.getBaseURI().resolve(uri).toASCIIString();
                  }
      
                  src.setSystemId(uri);
                  return src;
              } catch (URISyntaxException use) {
                  return null;
              } catch (IOException ioe) {
                  return null;
              }
          }
