PDF

class RPA.PDF.PDF

PDF is a library for managing PDF documents.

It can be used to extract text from PDFs, add watermarks to pages, and decrypt/encrypt documents.

Merging and splitting PDFs is supported by Add Files To PDF keyword. Read the keyword documentation for examples.

There is also limited support for updating form field values. (check Set Field Value and Save Field Values for more info)

The input PDF file can be passed as an argument to the keywords, or it can be omitted if you first call Open PDF. A reference to the current active PDF will be stored in the library instance and can be changed by using the Switch To PDF keyword with another PDF file path, therefore you can asynchronously work with multiple PDFs.

Attention

Keep in mind that this library works with text-based PDFs, and it can’t extract information from an image-based (scan) PDF file. For accurate results, you have to use specialized external services wrapped by the RPA.DocumentAI library.
