The focus of development in DynaPDF 4.0 was the development of a new PDF/A 2b and PDF/A 3b converter. The new converter should be able to completely rebuild PDF files.
This requirement has lead to the development of a new content parser that is able to completely regenerate and optimize content streams. This makes it possible to apply much more extensive repairs. Since all content streams will be rebuild, also references of the .notdef character can be removed (in PDF/A 1 it was allowed to reference the .notdef character directly but this is no longer allowed in PDF/A 2 and 3).
This increases the conversion rate drastically and completely error free and optimized PDF files will be created which render and print faster. This is not only interesting for PDF/A conversion, PDF files can also be normalized or just optimized.
Not anything that is possible with the new content parser is already available in corresponding functions. For example, the parser is also the new base for the rendering engine. Since it can read and write page contents, the development of a PDF editor is no problem anymore. Especially images and vector graphics can be edited in addition to text, which was not possible before. In the coming months the new parser will replace the old code more and more.
The icons of text and file attachment annotations, as well as the pre-defined stamps can now dynamically created in German, French, and English. This is especially important when viewing PDF files since nothing could be shown if the icons or stamps are not embedded.
FileMaker, Xojo and Real Studio
The new plugin for DynaPDF 4.0 will be available in the next days. We include new options there for optimizer to reduce image sizes.
