I create one project that convert a HTML to PDF/A then I deploy that project in a repository. :

`
public class PdfService {

public File FONT;
public File COLOR;

public PdfService() {
    setFont(new File(getClass().getClassLoader().getResource("NotoSerif-Regular.ttf").getFile()),
            new File(getClass().getClassLoader().getResource("sRGB.icc").getFile()));
}

public PdfService(File font, File color) {
    setFont(font, color);
}

private void setFont(File font, File color) {
    this.FONT = font;
    this.COLOR = color;
}



public File htmlToPdf1A(String html) throws Exception {
    File arquivo = File.createTempFile(UUID.randomUUID().toString(),".PDF");

    return htmlToPdf1A(html, arquivo);
}

public File htmlToPdf1A(String html, File arqDestino) throws Exception {
    System.out.println(FONT.getPath());
    PdfRendererBuilder.PdfAConformance conform = PdfRendererBuilder.PdfAConformance.PDFA_1_A;
    PdfRendererBuilder builder = new PdfRendererBuilder();
    PDDocument doc = new PDDocument();
    builder.usePDDocument(doc);
    builder.useFastMode();
    builder.useFont(this.FONT, "noto");
    builder.withUri("file://"+FONT.getPath());
    builder.usePdfVersion(conform.getPart() == 1 ? 1.4f : 1.5f);
    builder.usePdfAConformance(conform);

    String htmlCorrigido = tidyHtml(html, true);


    htmlCorrigido = htmlCorrigido.replace("<head>","<head> <style>" +
            " blockquote {\n" +
            "     border-left: .25em solid #dfe2e5;\n" +
            "     color: #6a737d;\n" +
            "     padding-left: 1em;\n" +
            "     margin: 20px 0!important;\n" +
            " }\n" +
            "@font-face {\n" +
            "  font-family: 'noto';\n" +
            "  /* Note: No trailing format tag is allowed. */\n" +
            "  src: url(file://"+FONT.getAbsolutePath()+");\n" +
            "  font-weight: normal;\n" +
            "  font-style: normal;\t\n" +
            "}\n" +
            "" +
            ".noto {\n" +
            "  font-family: 'noto', serif;\n" +
            "}\n" +
            "</style>");
    htmlCorrigido = htmlCorrigido.replace("<body>","<body class='noto editor'>");

    builder.withHtmlContent(htmlCorrigido, null);
    OutputStream baos = new FileOutputStream(arqDestino);
    builder.toStream(baos);
    builder.run();
    System.out.println(arqDestino.getAbsolutePath());
    return arqDestino;
}

private String tidyHtml(String htmlString, boolean isHtmlCompelto) {
    Tidy tidy = new Tidy();
    tidy.setDocType("omit");
    tidy.setXmlOut(true);
    tidy.setQuiet(true);
    tidy.setTidyMark(false);
    //Entender como funciona setWrapLen - Heryk
    tidy.setWraplen(100000);
    StringWriter swError = new StringWriter();
    tidy.setErrout(new PrintWriter(swError));
    StringWriter sw = new StringWriter();
    tidy.parse(new StringReader(htmlString), sw);
    String tidyHtml = sw.getBuffer().toString();
    tidyHtml = tidyHtml.replaceAll("(\r\n|\n|\r)+\\s*<", "<");
    if(!isHtmlCompelto){
        tidyHtml = tidyHtml.replace("<html>","");
        tidyHtml = tidyHtml.replace("<head>","");
        tidyHtml = tidyHtml.replace("<title>","");
        tidyHtml = tidyHtml.replace("</title>","");
        tidyHtml = tidyHtml.replace("</head>","");
        tidyHtml = tidyHtml.replace("<body>","");
        tidyHtml = tidyHtml.replace("</body>","");
        tidyHtml = tidyHtml.replace("</html>","");

    }
    return tidyHtml;
}

}`

Then I use that component in a springboot application so when I call my comp with this code:

PdfService pdfService = new PdfService(new File("/Users/fabioebner/Projetos/java/springboot/notificato-api/src/main/resources/NotoSerif-Regular.ttf"),new File("/Users/fabioebner/Projetos/java/springboot/notificato-api/src/main/resources/sRGB.icc"));

works fine. but when I use the ResourceLoader to load the font and color (with this code)
PdfService pdfService = new PdfService(resourceLoader.getResource("classpath:NotoSerif-Regular.ttf").getFile(),resourceLoader.getResource("classpath:sRGB.icc").getFile());

he can't find read the font..

anyone knwo why?

tks

hi @fabioebner ,

are you sure that resourceLoader.getResource("classpath:NotoSerif-Regular.ttf").getFile() return a file that can be then opened?

Quite sure this is the issue :).

@fabioebner are you building your project with maven?

If you have put your fonts in the src/main/resources folder you may have the same issue as #360 (comment) (where the binary files are filtered (and modified) by the maven-resources-plugin )

Generally, resources will be files while building with an IDE but not in the final jar. Better to use input streams.

Also:

  • use either builder.usefont or a font-face rule, not both.
  • use either withuri or withhtmlcontent not both.
  • the second argument of withHtmlContent should be the base uri.
