Improved HTML to PDF/A

With the latest advancements in pdfHTML 5.0.3, you can now generate PDF/A files directly from HTML even more easily than before! With just a few lines of code, the PDF/A conformance level and document output intent can be set directly in the HtmlConverter (Java/.NET) properties, creating fully compliant PDF/A files that adhere to archival standards.

What changed?

In earlier iterations of iText, while it was certainly feasible to generate PDF/A files through pdfHTML, the process was more complex than required, as developers were tasked with manually crafting a PdfADocument (Java/.NET) instance to add into the pdfHTML conversion process.

In our latest release, however, we've streamlined this procedure significantly: Now, developers can effortlessly create PDF/A documents by merely adjusting a few parameters to define the PDF/A conformance level and output intent in the ConverterProperties (Java/.NET) object. The underlying object instantiation processes are now handled seamlessly in the background, sparing developers the burden of manually setting up these objects.
