We just released new versions of all SetaPDF components.
Beside various tweaks and bug fixes here are some points to mention:
This release added support for handling PDF files which includes invalid data at the beginning of the file through the SetaPDF-Core component. Such files will normally invalidate all byte offset positions and all previous versions of SetaPDF were not able to handle this situation.
The SetaPDF-Extractor component will ignore invisible glyphs above visible glyphs now - in previous versions such constructs created a word break.
The SetaPDF-Signer component received several new demos which show the implementation of external signatures. We also added a demo for the Lacuna Web PKI plugin, which allows you to sign PDF documents in the browser.
Check the release notes of the components below.

Information
SetaPDF-Core Component
Feature
Added setTabOrder() and getTabOrder() in SetaPDF_Core_Document_Page_Annotations class.
Added method to normalize line breaks: SetaPDF_Core_Text::normalizeLineBreaks().
Added SetaPDF_Core_Document::getSaveMethod() and renamed $update parameter in save() method to $saveMethod (meaning is the same as before).
Added support for PDF documents with invalid data before their PDF file header.
Bugfix
Fixed a bug which occurs if AES encryption is used while the Length value of a stream is an indirect object which is already written because of the SetaPDF_Core_Document::SAVE_METHOD_REWRITE_ALL save method.
Prevent "String offset cast occured" notice in abstract reader class.
Fixed SetaPDF_Core_Document_Destination::findByName() when name was not found.
Tweak
Normalizes line breaks in SetaPDF_Core_Text_Block class.
Check for null bytes in file names before passing them to PHP functions to prevent warnings or notices.
Added support for faulty objects with a generation number higher than zero in object streams.
Allow date strings without "D:" prefix.
Demo
Updated get image sizes demo to handle rotated pages correctly.

Information
SetaPDF-Extractor Component
Feature
Implemented handling of invisible glyphs above visible glyphs. They are ignored now and will not trigger a word break in both Word and ExactPlain strategies.
Added setCleanStreamCallback() and getCleanStreamCallback() in the abstract strategy class.
Added SetaPDF_Extractor_ContentStreamCleaner class and implemented it as a default callback in all strategies. It allows you to clean up a content stream before it is parsed and will bring a performance boost for documents with e.g. very much vector operations.
Bugfix
Pass $_ignoreSpaceCharacter property in SetaPDF_Extractor_Strategy_ExactPlain to sub-instance.
Tweak
Optimized code in sorting functions.

SetaPDF-FormFiller Component
