  The technology for screenshots' detection has been improved, so that CLI tool is now able to identify screenshots as image blocks instead of trying to read the text from it.

• More flexibility when viewing a PDF document.
  A new option in CLI allows to manage the availability of PDF layers in the output PDF file. If the option is used, then PDF layers are assigned to MRC image planes, so that in some PDF viewers such as Adobe Acrobat it is possible to choose which layers to view. More details >>

• Possibility to control the decreasing of the licence counter units.
  With the new key you can now control the decreasing of licence counter units. It is especially useful in scenario, when the input images come from unknown sources and you do not know in advance which format and size the incoming documents have. To avoid license counter units loss, you can now use the new key, which will check the size of the pages in the input document. In case one of the document pages will be larger than A4 format the execution of the command will be stopped and a warning will be displayed. More details >>
