html without .ttf font

[testpasha777]

Hello, if html haven't .ttf font
Can i set some default font in code to solve this?

No, currently you cannot register a default font. However, you can mutate the document before rendering:

private static final String EXTRA_STYLE = 
        "* { font-family: 'noto'; }";

builder.addDOMMutator(doc -> {
                Element style = doc.createElement("style");
                Node node = doc.createTextNode(EXTRA_STYLE);
                style.appendChild(node);
                doc.getElementsByTagName("head").item(0).appendChild(style);
            });
builder.useFont(new File("path/to/noto.ttf"), "noto");

Still have problem with html without .ttf font. When mutate document and useFont java.lang.NullPointerException: null
at com.openhtmltopdf.pdfboxout.PdfBoxFontResolver.resolveFont
but .ttf font loaded com.openhtmltopdf.load INFO:: Loading font(raleway) from PDFont supplier now.

if use html with .ttf font and mutate document all works fine
com.openhtmltopdf.load INFO:: Loading font(raleway) from PDFont supplier now.
com.openhtmltopdf.load INFO:: Loading font(sansationregular) from InputStream supplier now.
com.openhtmltopdf.load INFO:: Loading font(sansationbold) from InputStream supplier now.

Any chance of aminimal sample?

org.w3c.dom.Document doc = DOMBuilder.jsoup2DOM(
                    Jsoup.connect(url)
                            .timeout(timeout)
                            .validateTLSCertificates(false).get());

            try (ByteArrayOutputStream os = new ByteArrayOutputStream()) {
                PdfRendererBuilder builder = new PdfRendererBuilder();
                builder.withW3cDocument(doc, url);
                builder.toStream(os);

                final String EXTRA_STYLE =
                        "* { font-family: 'raleway'; }";

                builder.addDOMMutator(document -> {
                    Element style = document.createElement("style");
                    Node node = document.createTextNode(EXTRA_STYLE);
                    style.appendChild(node);
                    document.getElementsByTagName("head").item(0).appendChild(style);
                });
                builder.useFont(new File(Html2PdfService.class.getResource("/font/Raleway-Regular.ttf").toURI()), "raleway");
                builder.run();

                return os.toByteArray();
            }

As a first thought, you need to take into account that a resource is not always a file. You could use the inputstream method to add a font instead.

Also, remember to use fast mode which will be the default after the next release:
builder.useFastMode().
