Apart from inputing free flowing text via the RedaFact portal, the PDF block article module allows exactly what's in the name; direct PDF block generation by filling pre-defined article templates.
This is of course very time saving during the page layout; using ready to place PDF article blocks, that are filled by the editor/reporter/journalist, can simply be dragged and dropped. Via the WYSIWYG preview in his browser interface, an author can simply write to fit . No need for changes during layout when text is too long or too short! Different text styles are defined by the various text blocks per template; styles need not be chosen manually as with the free flowing articel text input. And of course the article templates can contain pictures as well.
