When performing OCR to PDF we can choose what we would like to happen
There are 4 modes available - 3, 4, 5 and 6
Mode 3 - the image plane is preserved, and an invisible text layer is added. This makes it possible to redact text, but if you Edit text in the Kappris PDF Editor, e.g. change the spelling of a word or delete it, then what is being edited is the content of the invisible layer - the edited pdf will look unchanged. This is useful when you need to highlight or redact text in a scanned document but don't want the PDF to be altered.
Mode 4 - creates editable text and gives the same result as OCR to Word. This is useful when you need to edit a scanned PDF
Modes 5 and 6 give variations which can be experimented with but 3 or 4 are the most useful options.
The setting can be changed in each user's AppSetting.json file in C:\Program Files\Kutana\Kappris PDF Editor:
"OcrSubscription": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"StatDB": "%LOCALAPPDATA%\\Kutana\\statdata.db",
"OCRtoPDFMode": 4,
"ConnectedTimeout": 8000,
