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"));
I have added this line after getting my user agent (with
newFOUserAgent()) :
$file_out = new Java ('java.io.File', $path_to_png);
$fop_ua->setOutputFile($file_out);
I have now an error on my transform action :

someone has an example of code used to transform a FO file to several
png files with FOP ? I'am a bit confused right now ;-)
Thank you
Olivier
an idea ?

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: Using
BufferedOutputStream
* 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
