ImageGear features robust OCR (Optical Character Recognition) functionality which enables you to scan images and detect machine-written text in numerous languages. The results of the OCR operations can be returned as simple text or exported as a PDF document.

If you’re upgrading to v25 or later from v24.x or earlier and use the Recognition component, then there are some steps you’ll need to take to migrate your code to use the new OCR component. See Migrating from the Recognition Component to the OCR Component for details.
