Release iText 5.2.1

New release for iText 5.2.1 and XML Worker, continue reading to find out more.

release Notes:

IMPORTANT

All 5.2.x versions have been removed from our servers because of a serious flaw that was introduced when dealing with large PDFs!

I'm preparing to teach an iText class in Paris, and to give some demo's in Oakland. I'm currently making a new set of examples for some new chapters I'm going to write (maybe a third book, not a revision of the second edition, but a book with some advanced topics). Whilst making examples to explain the different options available in XML Worker, I found some bugs and I also thought about some functionality that was missing.

It would be a pity if I demonstrated my new examples in the next few weeks without having a new release with the latest changes, so that's why I made iText 5.2.1 one month after iText 5.2.0 was published. 

Changelog:

iText 5.2.1 Core

• Changes made by Paulo Soares
  • PdfReader now ignores unreachable pages (this only happens with broken PDFs).
• Changes made by Jeroen Nouws
  • PdfPublicSecurityHandler: added a check for InvalidKeyException when initializing cipher, if catched cipher will be initialized with the public key instead of the certificate (suggestion by Régis Ramillien).
• Changes made by Eugene Markovskyi
  • Fixed the unescapeXML() method so that it skips invalid characters
• Changes made by Alexander Chingarev
  • PdfNameTree: fixed crash on iterating through names tree when tree is splitted into several arrays (reported by Jason Rock who suggested a fix).
  • Added more convenient SimpleBookmark methods (e.g. to get child bookmarks of a certain outline object).
  • PdfName: added some new names
• Changes made by Bruno
  • Bugfix AcroForms: In some cases, Adobe Reader X asks if you want to "save changes" after closing a flattened PDF form. This was due to the presence of some unnecessary entries in the /AcroForm dictionary (for instance added when the form was created with OOo).
  • XfaForm: Added a readOnly parameter to the fillXfaForm() method.
  • Extra ColumnText method to check if an Element is allowed in a column.
  • Paragraph: added a cloneShallow() method and a method that breaks up a Paragraph into a list of paragraphs, lists and tables.
  • ColumnText now breaks up a Paragraph before adding it to the stack. This prevents flattening of the content nested inside the paragraph (deep nesting still isn't supported).
  • Nested Paragraph objects can now have different values for the leading.
  • Files loaded from deep nested jars or ears in jBoss are referred to with vfszip: (Bug report #3512734)

XML Worker 1.1.3

• Changes made by Eugene Markovskyi
  • Cleaning up different spacing issues.
  • Fixing justified alignment.
  • Now XMLWorker uses 1.2 multipliedLeading as default for Paragraph.
  • Cleaning up some minor issues regarding HTML tables.
• Changes made by Bruno Lowagie
  • ParagraphCssApplier: if the fontSize < 0 (which doesn't make sense), all parameters are calculated using the wrong base.
  • Added a test to avoid a NPE in PathTag.
  • Added a convenience method to add a substitution font to XMLWorkerFontProvider.
  • Replacing String[] with String... in FileRetrieveImpl.
  • Adding a constructor to FileRetrieveImpl with a File object defining a root directory as parameter.
  • Adding a setFileRetrieve() method to the CSSResolver interface.
  • XMLWorkerFontProvider: With DONOTLOOKFORFONTS, you can avoid that the FontProvider spends time on registering font directories (you may not need them).
  • XMLWorkerHelper: If a charset is defined, you want to use it when parsing XML.
  • Added a convenience class that can be used to parse XML to a list of elements: ElementList
  • XMLParser: detecting the encoding didn't work in some environments because the mark was invalid (and a call to reset() failed). Now we expect a '>' in the first 1028 characters.
  • Added setChunkCssAplier() method to the CssAppliers interface
