Hello,
I'm trying the new intermediate format from the article
Performance Analysis for Apache FOP's new Intermediate Format of Jeremias
Märki.
and his program
(http://www.jeremias-maerki.ch/download/fop/FOP%20Benchmarks.zip).
Thanks to Jeremias.
So, I have write a small file.xml and a file xml2fo.xsl for the
transformation xml -- fo.
When I do a test with the FOPBenchmark,
I obtain a duration of 0,39 seconds! in the results.xml (with the variant
from-it) :
scenario name=xml2fo variant=from-if
descriptionApache FOP: file.xml example, rendering from Intermediate
Format/description
environment
value name=java.specification.version1.6/value
/environment
run idx=0
run
value name=target-formatPDF/value
page-count2/page-count
duration390/duration
file mime=application/pdf;mode=painter
size=24294file:/C:/Users/greg/workspace/FOPBenchmarks/benchmarks/dev/05/file.if.pdf.if.if.pdf
/file
/run
/run
/scenario
So, I take the class java bellow (for a program) :
public class Main {
public static void main(String[] args) {
FopFactory fopFactory = FopFactory.newInstance();
try {
long startTime = System.nanoTime();
File baseDir = new File(.);
File outDir = new File(out);
final File xmlfile = new File(baseDir, xml/file.xml);
File xsltfile = new File(baseDir, xsl/xml2fo.xsl);
File iffile = new File(outDir, file.if.xml);
File stampxsltfile = new File(baseDir, xsl/ifstamp.xsl);
File pdffile = new File(outDir, file.if.pdf);
Main app = new Main();
// Setup output
OutputStream out = new java.io.FileOutputStream(pdffile);
out = new java.io.BufferedOutputStream(out);
try {
FOUserAgent userAgent = fopFactory.newFOUserAgent();
String mime = MimeConstants.MIME_PDF;
IFDocumentHandler targetHandler =
fopFactory.getRendererFactory().createDocumentHandler(
userAgent, mime);
IFUtil.setupFonts(targetHandler);
targetHandler.setResult(new StreamResult(pdffile));
IFParser parser = new IFParser();
Source src = new StreamSource(iffile);
Source xslt = new StreamSource(stampxsltfile);
TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(xslt);
SAXResult res = new
SAXResult(parser.getContentHandler(targetHandler, userAgent));
transformer.transform(src, res);
} finally {
out.close();
}
long estimatedTime = System.nanoTime() - startTime;
System.out.println(estimatedTime : + estimatedTime + \n);
} catch (Exception e) {
e.printStackTrace(System.err);
System.exit(-1);
}
}
}
I can obtain a file.if.pdf (2 pages), but the transformation take 2.4
seconds !
I think it's very a long duration when I see duration390/duration in my
results.xml !
Do you know why when I use a class java the duration is very long ?
What can I do for obtain a more small duration ?
Thank.
