Converting HTML to PDF Using iText7

Question: How to Respect CSS Positioning Rules?

Previously, developers faced difficulties converting HTML to PDF using HTMLWorker due to deprecated methods and lack of CSS support. XMLWorker also had limitations, particularly with image positioning. To resolve these issues, iText 7 and the pdfHTML add-on were developed.

Answer:

The simplified approach to converting the provided HTML to PDF using iText 7.1.0 pdfHTML 2.0.0 is:

public static final String SRC = "src/main/resources/html/sample.html";
public static final String DEST = "target/results/sample.pdf";

public void createPdf(String src, String dest) throws IOException {
    HtmlConverter.convertToPdf(new File(src), new File(dest));
}

This results in a PDF that respects CSS positioning, including the image on the right.

Additional Thoughts:

• Upgrade to iText 7 and pdfHTML 2 for enhanced features and support.
• Respect the AGPL licensing if using iText for free in open source projects.
• Commercial licenses are required for closed source/proprietary product use.
