I am trying to migrate iText from 7.0.4 to 7.2.5. There were few breaking change in terms of package that I fixed.

The main issue I am now running into is the html to PDF is adding padding / line spacing . This is major blocker since the PDF (letters) to be out of alignment and cannot be printed as per previous spec.

Anyone that has run into this issue before ? I can confirm that the html are the same and the output with change of jars are causing this issue.

   private void createPdf(String src, String dest, String resources) throws Exception
    {
        FileOutputStream outputStream = null;
        Document doc = null;
        PdfWriter pdfWriter = null;
        PdfDocument pdfDoc = null;
        FileInputStream inputStream = null;

        try
        {
            outputStream = new FileOutputStream(SecurityUtil.checkFileName(dest));

            WriterProperties writerProperties = new WriterProperties();
            // Add metadata
            writerProperties.addXmpMetadata();
            writerProperties.setFullCompressionMode(true);

            pdfWriter = new PdfWriter(outputStream, writerProperties);
            pdfDoc = new PdfDocument(pdfWriter);
            doc = new Document(pdfDoc);
            doc.setMargins(50, 50, 100, 50);

            pdfDoc.getCatalog().setLang(new PdfString("en-US"));
            // Set the document to be tagged
            pdfDoc.setTagged();
            pdfDoc.getCatalog().setViewerPreferences(new PdfViewerPreferences().setDisplayDocTitle(true));

            // Set meta tags
            PdfDocumentInfo pdfMetaData = pdfDoc.getDocumentInfo();
            pdfMetaData.setAuthor("");
            pdfMetaData.addCreationDate();
            pdfMetaData.getProducer();
            pdfMetaData.setCreator("");
            pdfMetaData.setKeywords("letter, accessibility");
            pdfMetaData.setSubject("PDF accessibility");
            // Title is derived from html

            // pdf conversion
            ConverterProperties props = new ConverterProperties();
            FontProvider fp = new DefaultFontProvider(true, true, true);

            LOGSERVICE.logInfo("Font resource Folder:" + resources);

            if (!StringUtil.isEmptyAfterTrim(resources))
            {
                fp.addDirectory(resources);
            }

            props.setFontProvider(fp);
            props.setBaseUri(resources);
            // Setup custom tagworker factory for better tagging of headers
            DefaultTagWorkerFactory tagWorkerFactory = new AccessibilityTagWorkerFactory();
            props.setTagWorkerFactory(tagWorkerFactory);
            
            inputStream = new FileInputStream(SecurityUtil.checkFileName(src));
            HtmlConverter.convertToPdf(inputStream, pdfDoc, props);
        }
        finally
        {
            if (doc != null)
                doc.close();
            if (pdfDoc != null)
                pdfDoc.close();
            if (pdfWriter != null)
                pdfWriter.close();
            if (outputStream != null)
                SecurityUtil.safeClose(outputStream);
            if (inputStream != null)
                SecurityUtil.safeClose(inputStream);
        }
    }
