The PDF pack contains activities designed to extract data from PDF and XPS files and store it into string variables. The data can be extracted from the entire document or from a range of pages specified under the Range property found in each of the activities.
In the case of scanned documents, data extraction can also be achieved by using OCR-based activities, Read PDF With OCR and Read XPS With OCR. To select one of the three OCR engines specific to UiPath, Google OCR, Microsoft OCR and Abbyy OCR, simply drop the engine in the body of the activity.
If you want to use the UiPath.PDF.Activities package in the same project with the UiPath.IntelligentOCR.Activities package, you need to use either version 2.x of both, or versions 3.x of both. UiPath.IntelligentOCR.Activities version 3.0 and higher is incompatible with a UiPath.PDF.Activities version lower than 3.0, and a UiPath.PDF.Activities version 3.0 or higher is incompatible with an UiPath.IntelligentOCR.Activities version lower than 3.0.
