I'm using thymeleaf to process the HTML page that would be then passed to openhtmltopdf to generate a PDF with Arabic content.
the issue if I'm trying to generate using
withHtmlContent(String html, String baseUri)
then:

  • the PDF will have #### for any Arabic Content.
  • what is baseUri and how I should set it?
  • if I just pass the HTML page location using withUri(String uri), Arabic is rendered, the issue with this is I need to process the HTML to be dynamic "generate a purchase order"

check below sample code:

public void generateOpenPDF() throws Exception {
    String htmlContent = "<html xmlns=\"http://www.w3.org/1999/xhtml\"><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"/><style>@font-face{font-family: noto; src: url('NotoNaskhArabic-Regular.ttf');}body, body *{font-family: 'noto', sans-serif;}</style></head><body><div class=\"border\"><h1>عربي</h1></div></body></html>";

   ByteArrayOutputStream os = new ByteArrayOutputStream();
   PdfRendererBuilder builder = new PdfRendererBuilder();
   builder.useUnicodeBidiSplitter(new ICUBidiSplitter.ICUBidiSplitterFactory());
   builder.useUnicodeBidiReorderer(new ICUBidiReorderer());
   builder.defaultTextDirection(TextDirection.RTL); // OR RTL
	    
   builder.withHtmlContent(htmlContent, "/tmp");
        
   builder.toStream(os);
   builder.run();
   byte[] pdfAsBytes = os.toByteArray();
   os.close();
   Path file = Paths.get("/tmp/the-file-name.pdf");
   Files.write(file, pdfAsBytes);
}

Hi @yalmuhaidib
Sorry for the late reply. You use a relative link to the font in the HTML, so you need a base URL to resolve relative URLs. Try using a file:// URL.

builder.withHtmlContent(htmlContent, "file:///absolute/path/to/font/dummy.html");

hi!

Same problem with greeks i can not understand the content of the dummy.html
Any example would be usefull.
When i use the builder.withUri(url); and in the html there is the reference to the font works fine.
I can not do to work with builder.withHtmlContent(htmlContent...

thanx

Solved!
One solution is to add

<style>
@font-face {
    font-family: 'cjk';
    src: url('file:///d:/deleme/java/webServices/WebServicesTools/resources/Calibri.ttf');
}

body
{
font-family:cjk;
}
</style>

inside htmldata and leave the second arg of withHtmlContent ""

Hi @JimTheod
Yes, using complete paths is one solution. However, you should be able to use relative paths. The dummy.html doesn't actually have to exist. It's the path to your relative resources that is important. Sorry for the confusion. So in your case:

<style>
@font-face {
    font-family: 'cjk';
    src: url('Calibri.ttf');
}

body
{
font-family:cjk;
}
</style>

and

builder.withHtmlContent(htmlContent, "file:///file:///d:/deleme/java/webServices/WebServicesTools/resources/dummy.htm");

I've tested this, but on a mac, maybe it is not working in Windows?

Thanx for quiq reply!

Yes you are right if i use

<style>
@font-face {
    font-family: 'cjk';
    src: url('Calibri.ttf');
}

body
{
font-family:cjk;
}
</style>

and then set only the path works fine

builder.withHtmlContent(htmlContent, "file:///file:///d:/deleme/java/webServices/WebServicesTools/resources/");
