Creating multiple PNG files is only supported if output is done to a
file (seems to be the case here). In this case, you have to set the
output file on the user agent in addition to the output stream:

useragent.setOutputFile(new File("D:/out.png"));

thanks a lot , I will try this and report to the list

Hey


Another beginner question

I use fop 0.92 but I'am consedreing moving to trunk soon

I tried to generate png from a fo file

using command line works fine :

java -jar fop.jar -fo /tmp/test.fo -png ../../../web/uploads/test.png


give severals png test.png, test2.png - one png for each page.

I am now trying using the API trought php-java-bridge (quite similar
if we where using java)

here my code :

              // Instanciate & configure FOP user agent
               $fop_factory = new JavaClass
('org.apache.fop.apps.FopFactory');
               $fop_factory = $fop_factory->newInstance();
               $fop_factory->setUserConfig(new Java('java.io.File',
sfConfig::get('sf_app_config_dir').'/fop.xconf'));
               $fop_ua = $fop_factory->newFOUserAgent();

                /*

* Setup output stream. Note: UsingBufferedOutputStream

                * for performance reasons (helpful with
FileOutputStreams).
                */
               $out = new Java('java.io.FileOutputStream',
$path_to_png);
               $out = new Java('java.io.BufferedOutputStream', $out);

               // Construct fop with desired output format
               $fop_mime_constants = new JavaClass
('org.apache.fop.apps.MimeConstants');
               $fop = $fop_factory->newFop($fop_mime_constants-

MIME_PNG, $fop_ua, $out);


               // Setup JAXP using identity transformer
               $transformer_factory = new JavaClass
('javax.xml.transform.TransformerFactory');
               $transformer_factory = $transformer_factory-

newInstance();

               $transformer = $transformer_factory->newTransformer();

               // Setup input stream
               $src = new Java
('javax.xml.transform.stream.StreamSource', $path_to_fo);

               // Resulting SAX events (the generated FO) must be
piped through to FOP
               $res = new Java('javax.xml.transform.sax.SAXResult',
$fop->getDefaultHandler());

               // Start XSLT transformation and FOP processing
               $transformer->transform($src, $res);

the problem is just the first png is generated  ! :-(

An idea ?

Thank you for your advices and making fop wich is great

Olivier
