iText7 don't work when I use CSS3 function target-counter in property content












2















I am very new to iText7. I am trying to create a pdf from a dynamic HTML string. So far I have been able to create the pdf using HtmlConverter.ConvertToPdf(). But the problem is that I need have a table of contents with chapters and page numbers at begin of the document. To do that, I wrote in my CSS file:



@page {
margin: 40mm 17mm 17mm 17mm;
size: A4 portrait;
@top-center {
content: element(header);
width: 100%;
}
@bottom-right-corner {
content: counter(page);
}
}

a::after {
content: leader('.') target-counter(attr(href), page)
}


And I wrote in my HTML file:



<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<head>
<title>Good Thymes Virtual Grocery</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" th:href="@{${baseUrl} + '/static/css/relatorio_fiscalizacao.css'}"/>
</head>
<body>
<h1>ÍNDICE</h1>
<ul style="page-break-after: always;">
<li><a href="#ch1">STAFF</a></li>
<li><a href="#ch2">OPERATION DATA</a></li>
</ul>

<h1 id="ch1" class="chapter">STAFF</h1>
<p style="page-break-after: always;">....</p>

<h1 id="ch3" class="chapter">OPERATION DATA</h1>
<p style="page-break-after: always;">....</p>

</body>
</html>


And finally, I have a component in my Spring Boot application:



@Component
public class PdfGeneratorUtil {
@Autowired
private TemplateEngine templateEngine;

@Autowired
ServletContext servletContext;

@Autowired
private ApplicationContext context;

@Value("${baseUrl}")
private String baseUrl;

public ByteArrayOutputStream createPdf(String templateName, Map<String, Object> map, final HttpServletRequest request, final HttpServletResponse response) throws Exception {
Assert.notNull(templateName, "The templateName can not be null");

System.out.println(baseUrl);

map.put("baseUrl", baseUrl);

IWebContext ctx = new SpringWebContext(request, response, servletContext, LocaleContextHolder.getLocale(), map, context);


String processedHtml = templateEngine.process(templateName, ctx);
ByteArrayOutputStream os = new ByteArrayOutputStream();

try {
ConverterProperties converterProperties = new ConverterProperties();
HtmlConverter.convertToPdf(processedHtml, os, converterProperties);
System.out.println("PDF created successfully");
}
finally {
if (os != null) {
try {
os.close();
} catch (IOException e) { /*ignore*/ }
}
}

return os;
}
}


iText converts to Pdf fine. But the chapters from table of contens come up without the number of pages. And Log returns "Content property target-counter is either invalid or uses unsupported function."



I saw the file CssContentPropertyResolver.java and I realized that the code not treat the CSS function "target-counter". So, my question is: There is an other way to do that, maybe creating custom CSS appliers like this tutorial? Or maybe other way? If not, anybody know any other library that I could use instead iTextPdf?
