The Tesseract OCR application will perform an OCR operation to a image using the open source tool known as Tesseract. 

Features

Some of the features of the Tesseract OCR application include:

• Multiple language support.
• Multiple page segmentation modes.
• Multiple image creation color scales and formats.

Limitations 

Since Tesseract is a third party tool that needs to be set up separately from Aspire,  the Tesseract OCR application has the following limitations as per API:

• Tesseract must be installed separately.
• Before using a Tesseract feature, it must be properly installed.
  • For example: OCR for other languages as French, Spanish among others.
• While performing OCR in a file, the order where the languages are provided will affect the output.
  • See here the documentation here.
  • List of all available languages, see here. 
• Multi-page tiff file is not supported right now.

Future Development Plan
