Text Recognition via OCR Add-on

C++ OCR Library to Convert Text in Images to Usable Word-Processing Text

Ensure the Capture of All Data

Various scenarios may call for users to extract text from an image in
order to be able to manipulate it for data usage or storage.

Use All Your Data

With an optical character recognition (OCR) library, you can empower users to extract text from scanned images to manipulate that content, whether to edit, save or reuse it. You can also produce searchable PDF documents.

Supports client-side and server-side deployment on Windows and Linux with no limit to the server-side language

Supports client-side deployment.


With a Server-Side Deployment

Users upload an image to the server for OCR processing within the server. There is no need to download an OCR engine to a client machine. The downside of this approach is a lack of support for offline OCR.

With a Client-Side Deployment

Users need to download and install the OCR module upon their first visit to the web page. This approach currently only supports Windows clients.
