iText 5.5.8

For this release, we combined the itextpdf, pdfa, xtra and xmlworker repositories on GitHub. You no longer need to download XML Worker separately, it is included in the ZIP file below. You'll have to make small changes to your development environment if you import the iText source code.

A new site, a new release! We've been working very hard on a new web site that would contain more code samples and answers to questions. We've also made it easier to find the information you need by creating different, easy-to-understand categories, but also through better search functionality and the use of tags.

iText 5.5.8 fixes a problem with digital signatures that was accidentally introduced in version 5.5.7. While we were at it, we also improved the verification of OCSP responses. There were also problems when signing PDFs that are compliant with the PDF/A-2, PDF/A-3 and ZUGFeRD standard. Those are now fixed.

Other improvements involve:

• Fonts: there were issues with some Noto fonts, we fixed the range of characters in the ToUnicode table, we provided a fallback mechanism in case of absent OS/2 tables,
• Annotations: fixed some scaling issues and some flattening problems when skew and rotation are involved,
• PdfReader: fixed partial reading when a PDF file is imported as a byte array,
• Tagged PDF: fixed a problem with the structure tree when using page events,
• Page labels: we received code contributions from Nick Park that improve page label extraction.

We also have a new RUPS release. You can now click a stream in tree view to inspect its contents in a new window. This allows the user to keep a stream open while looking at other information such as the resources (fonts, XObjects, images,...) used by the stream.

For the full list of updates, see the Changelog 5.5.8.

iText 5.5.7

There's a new 60-page tutorial in the works about creating e-Invoices with iText. This book will be presented at Adobe's Headquarters in San Jose at the PDF Association's PDF Technical Conference. In the pdfa jar of iText 5.5.7, you'll find code that allows you to create ZUGFeRD invoices as a PDF document with an XML attachment that complies either with the ZUGFeRD Basic profile or the ZUGFeRD Comfort profile. All you need to do to create the XML, is to implement either the BasicInvoice or the ComfortInvoice interface. These are invoices that consist of nothing but getX() methods in which you provide the content of your invoice (such as seller, buyer, invoice lines,...). The functionality is currently released in beta, let us know if you want more info before the official release of the tutorial.

This release also brings several improvements, especially in these areas:

• The CleanUp functionality: several bug fixes; we've also resolved some inconsistencies between iText and iTextSharp.
• Forms: fixed some problems with special (or missing) fonts, fixed some edge cases when merging forms.
• Tables: fixed edge case errors, for instance problem:
  • with skip first header/last footer,
  • when splitting rows,
