Slow rendering with Linux OS

[girisatna girisatna]

Hi,

I am using

<flying-saucer-pdf.version>9.1.22</flying-saucer-pdf.version>

and eclipse temurin 17 as JDK running in Ubuntu Linux.

In my code renderer.layout() takes long time (4-5mins) when the document contains slahed o(for ex o in 'udløber') of norwegian characters.

below is my similar code running in Linux. Thanks.

with the below code,we also use custom fonts html in .setDocumentFromString() method.

private void generateHtmlToPdf() throws Exception {
File inputHTML = new File(HTML_INPUT);
Document inputHtml = createWellFormedHtml(inputHTML);
File outputPdf = new File(PDF_OUTPUT);
xhtmlToPdf(inputHtml, outputPdf);
}

private Document createWellFormedHtml(File inputHTML) throws IOException {
String bytes = new String(Files.readAllBytes(inputHTML.toPath()), "UTF-8");
Document document = Jsoup.parse(bytes);
document.outputSettings()
.syntax(Document.OutputSettings.Syntax.xml);
// document.charset(Charset.forName("Cp1252"));
return document;
}

private void xhtmlToPdf(Document xhtml, File outputPdf) throws Exception {
try (OutputStream outputStream = new FileOutputStream(outputPdf)) {
ITextRenderer renderer = new ITextRenderer();
SharedContext sharedContext = renderer.getSharedContext();
sharedContext.setPrint(true);
sharedContext.setInteractive(false);
//sharedContext.setReplacedElementFactory(new CustomElementFactoryImpl());
renderer.setDocumentFromString(xhtml.html());
renderer.layout();
renderer.createPDF(outputStream);
}
}

Hi Girisatna!

Why do you report an issue in a very old version of FlyingSaucer?

Please check if the problem exists in the latest FlyingSaucer 9.8.0.

NB! Anyway, you will need to create a reproducible example. Ideally, a simple github project with just one test. 

Because I cannot reproduce the problem: FS 9.1.22 generates a PDF with "udløber" word very quickly (300ms) on my machine.
