*I saw one of the blogs and they said to use the following snippet but I am
not sure where to use that in my code*
for (Element e : elements) {
if (!ColumnText.isAllowedElement(e))
continue;
// do stuff
}
*This is my code:*
public String generatePDF(String tempFolder,String
completeHtmlFilePath,NodeBO renditionRequestBO)throws
FileNotFoundException, IOException, DocumentException,
CssResolverException {
<< some code stuff here>>
com.itextpdf.text.Document document = new com.itextpdf.text.Document();
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream(pdfFileNameWithPath));
document.open();
HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
//htmlContext.setLastMarginBottom(100.0f);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
CSSResolver cssResolver = XMLWorkerHelper.getInstance()
.getDefaultCssResolver(true);
Pipeline<?> pipeline = new CssResolverPipeline(cssResolver,
new HtmlPipeline(htmlContext, new PdfWriterPipeline(document,
writer)));
XMLWorker worker = new XMLWorker(pipeline, true);
XMLParser p = new XMLParser(worker);
File input = new File(completeHtmlFilePath);
p.parse(new InputStreamReader(new FileInputStream(input), "UTF-8"));
document.close();
return pdfFileNameWithPath;
}
}
