The Tesseract OCR application will perform an OCR operation on an image file using the open-source tool known as Tesseract. 

Features

Some features of the Tesseract OCR application include:

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

Limitations 

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

• It 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 the documentation here.
  • List of all available languages, see here. 
• Multipage tiff files are not supported right now.

Future Development Plan  

• Add multipage tiff support
