Introduction

The LEADTOOLS OCR Module provides programming tools for quickly and easily adding document optical character recognition (OCR) technology into software applications. Using the LEADTOOLS OCR Module, programmers can perform character recognition on document images and output recognized text to over 20 file formats. The PDF OCR Plug-in extends the LEADTOOLS OCR Module to add PDF output support.

LEADTOOLS makes OCR development easier with auto-zone detection, manual zone creation, auto-orientation, document image clean up, and the use of preset values for common document images to improve recognition results. The LEADTOOLS OCR Module supports over 100 languages, as well as output document options like document margins and paragraph options.

Supported output formats include:

Key Features:

Additional Features:

Three specialized OCR recognition engines are supported. Each document may contain multiple OCR zones, and each zone may use any of the following OCR engines:

MOR OCR Engine

This module can safely handle A3 size (11.69" x 16.54") portrait and landscape images with 300 dpi resolution. It recognizes machine printed text from printed publications, laser or ink-jet printers, and electric typewriters. Output from mechanical typewriters in good condition, and from  letter- or near-letter quality (LQ, NLQ) dot-matrix printers is also acceptable.

MTX (Mtext) OCR Engine

This module can safely handle A3 size (11.69" x 16.54") portrait and landscape images with 300 dpi resolution. It recognizes machine printed text from printed publications, laser or ink-jet printers, and electric typewriters. Output from mechanical typewriters in good condition, and from draft-quality, letter-quality, or near-letter quality dot-matrix printers is also acceptable. Only images with the following resolution ranges are supported: 90-110, 160-240, 280-320, 400, 600. This module does not process images larger than 6600 pixels in either width or height.  

FireWorX OCR Engine

This module recognizes machine printed text from printed publications, laser or ink-jet printers, and electric typewriters. Output from mechanical typewriters in good condition, and from  letter- or near-letter quality (LQ, NLQ) dot-matrix printers is also acceptable.

Supported Environments

The toolkit comes in Win32 and x64 editions that can support development of software applications for any of the following environments:
