pdf render and chinese characters issues

Hello guys,

I have a script report that builds a html string containing the report.

then I export the report like this:

if(outputFormat =="pdf")
	return renderer.get("pdf").render(report.toString())

return new CompiledHtmlReportImpl(report)

the report contains some chinese words.. when I run the report in preview(on reportserver) or export it to HTML, the chineses words work fine however when i export them to PDF, the chinese words dont show up.

I believe that this render function uses a font that doesnt support chinese?

Is there any place where we can change this? What would be the best approach to fix this?

Thanks in advance

Regards,
Marcos

Re: pdf render and chinese characters issues

Hi Marcos,

what we use behind the scenes is the flying-saucer library. Flying-saucer allows you to embed custom fonts via CSS as

@font-face {
        font-family: "UbuntuMono";
        src: url("UbuntuMono-R.ttf");
        -fs-pdf-font-embed: embed;
        -fs-pdf-font-encoding: Identity-H; 
}

* {
        font-family: "UbuntuMono";
}

For further reference have a look at https://code.google.com/p/flying-saucer/wiki/FAQPDF

Hope this helps.

Arno

Thanks for replying, Arno.

I tried to add a custom font but I got an error.

this is my script

if(outputFormat =="pdf")
	return renderer.get("pdf").render(report.toString())

return new CompiledHtmlReportImpl(report)

it renders HTML ok, however when I export to pdf I get the following error :

Apparently more people have had this issue as well, and as per the following forum, the solution was removing custom font?
http://stackoverflow.com/questions/2823 … rexception

is there any way we can set a default font so we dont need to create a css custom font?

Re: pdf render and chinese characters issues

Hi Marcos,

I haven't really looked at this yet, but on a first glance it seems that the script cannot locate the font. Have you tried providing
a proper URL for the font, that is, exchange  src: url("UbuntuMono-R.ttf"); for a URL which actually points to the correct ttf file?

Cheers

Re: pdf render and chinese characters issues

just checking the source and found that:

public class PdfRenderer implements ScriptReportRenderer {

	@Override
	public String getName() {
		return "pdf";
	}

	@Override
	public CompiledReport render(Object input)  {
		ITextRenderer renderer = new ITextRenderer();
		try {
			renderer.getFontResolver().addFont("org/dejavu/fonts/ttf/DejaVuSans.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
		} catch (DocumentException e1) {
			e1.printStackTrace();
		} catch (IOException e1) {
			e1.printStackTrace();
		}
		
		renderer.setDocumentFromString((String) input);

		ByteArrayOutputStream os = new ByteArrayOutputStream();
		renderer.layout();
		try {
			renderer.createPDF(os);
			os.close();
		} catch (Exception e) {
			throw new RuntimeException(e);
		}

		byte[] cReport = os.toByteArray();

		return new CompiledPdfReport(cReport);
	}

}

just considering changing that font DejaVuSans.ttf by one that could render chinese words?
