Release notes v0.4.0 v0.4.0 brings the overview view, where the uploaded pdf is displayed. This overview is the starting point for the extraction process, from there the user will be able to switch to any of the three steps of the process. Currently, none is implemented, but this will come in the next version. Also, this version brings some improvements to the preprocessing of the uploaded pdf file: requests to the backend are now chained, s.t. just a certain amount of requests are open all the time. This amount is currently set to 1, i.e. just one request is done after the previous has been finished (successfully). This means, each page is OCRed after the previous one. This does not scale very well for large pdfs, but brings the benefit of supporting pdfs with any page number size. Future versions will include the yet missing steps of the process.
