Hello All,

I am pleased to introduce a new graphical interface for Tesseract 4.0 built specifically for the .Net platform. 

Here are some attributes of TesseractStudio.Net:
  • Simple graphical interface.
  • Improved performance by parallel processing of multipage documents.
  • Simultaneous display of images and hidden OCR text.
  • Create, edit, split, merge, move, resize or delete recognized words.
  • Unlimited undo/redo stacks.
  • Works with image/PDF files with or without prior OCR data.
  • Preserves non-image PDF components, such as visible text.
  • Integrated spell checker.

Thank you,

Farhad Khalafi
Opait Software

    • Save as searchable PDF where each page has a single image which overlays hidden OCR data.
      • Maintain original color if applicable, or
      • Convert to grayscale before saving, or
      • Convert to monochrome using a dithering algorithm, or
      • Convert to monochrome using dynamic or specified thresholding.

      • Use a visible font for OCR and other text objects.
      • Pick standard type 1 fonts to reduce PDF size.
      • Embed any available font into the PDF file (with some overhead).
      • Format OCR and other text to approximate the original layout (without graphics).

We have released version 1.5 of Tesseract Studio for .Net. 
  • Displays recognized words with average confidence scores for easier identification of suspect words.
  • Uses direct PDF generation from recognized words. Previously we used the built-in PDF generator and a temporary file. This version avoids the temporaries for better performance.
