The need to restructure is more and more widespread. Office software cannot read these destructured documents. ADOBE is developing tools to transform these destructured files into usable files by most office software.
Likewise, a great deal of research has over the last decade focussed on how to restructure PDF files which contain text or spreadsheet type tables, but none of this research looks at the problem of restructuring data which contains both text and drawings. There are solutions available which enable all the graphic items contained in PDF files to be displayed, eg. PACK’ELEC by Algo’Tech Informatique.
However, generally, this software only deals with PDF files, whereas there are also many other types of destructured documents. These tools often find it difficult to deal with certain types of PDF file, in particular, when fonts are embedded in the PDF file. Recreating text based on letters is often problematic when the text is slanting or vertical. Purely graphic objects are, most of the time, left as they are, eg. a segment which is an axis straight line is made up of as many segments as there are lines, making it difficult or impossible to deal with.
