If a PDF contains both images and native text, which activity should be employed to read all the text?

To read all the text within a PDF that contains both images and native text, utilizing the "Read PDF with OCR" activity is the most effective approach. Optical Character Recognition (OCR) technology is specifically designed to interpret and extract text from images. In cases where text is embedded within images—such as scanned documents—this method is essential because traditional methods that only read native text would miss any text that exists in graphical format.

The other methods may only target native text or may not extract text embedded in images effectively. Thus, the use of OCR ensures comprehensive text extraction from the entire document regardless of its format, making it the optimal choice for handling PDFs with mixed content.
