How to add external CSS while generating PDF?

Question

Currently i am using following code to generate PDF in a JSP file:

response.setContentType(\"application/force-download\");                                               


        

Answer 1

Please take a look at the ParseHtmlTable1 example. In this example, we have HTML stored in a StringBuilder object and some CSS stored in a String. In my example, I convert the sb object and the CSS object to an InputStream. If you have files with the HTML and the CSS, you could easily use a FileInputStream.

Once you have an InputStream for the HTML and the CSS, you can use this code:

// CSS
CSSResolver cssResolver = new StyleAttrCSSResolver();
CssFile cssFile = XMLWorkerHelper.getCSS(new ByteArrayInputStream(CSS.getBytes()));
cssResolver.addCss(cssFile);

// HTML
HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());

// Pipelines
PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);

// XML Worker
XMLWorker worker = new XMLWorker(css, true);
XMLParser p = new XMLParser(worker);
p.parse(new ByteArrayInputStream(sb.toString().getBytes()));

Or, if you don't like all that code:

ByteArrayInputStream bis = new ByteArrayInputStream(htmlSource.toString().getBytes());  
ByteArrayInputStream cis = new ByteArrayInputStream(cssSource.toString().getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, bis, cis);
