About LEADTOOLS Document Suite SDK

Build end-to-end document and imaging solutions with editing, scanning, OCR, OMR, forms recognition, PDF and more.

LEADTOOLS Document Suite SDK is a comprehensive collection of LEADTOOLS SDK features designed to build end-to-end document solutions that require OCR, MICR, OMR, ICR, barcode, forms recognition and processing, PDF, HTML5/JavaScript Zero-footprint viewing, conversion, print, capture, archival, annotation, and image viewing functionality. This powerful set of tools utilizes LEAD's award-winning image processing technology to intelligently identify document features that can be used to recognize and extract data from any type of scanned or faxed form image. LEADTOOLS Document Suite includes the LEAD OCR Engine, which powers the text and forms recognition capabilities bundled with this product.

LEADTOOLS Document Suite SDK Includes:

  • Documents - Create, Load, Save, View, Convert, Sign
    • Document Framework - The LEADTOOLS Document Framework is a comprehensive collection of .NET (C# & VB) and HTML5/JavaScript development libraries and components to create, read, analyze, mark up, and update raster and SVG images, annotations, thumbnails, text data, and metadata.
    • Document Analyzer - The LEADTOOLS Document Analyzer SDK Library intelligently identifies document components and zones in text-based office documents (DOC, DOCX, XLS, XLX), PDFs, and document images (JPG, TIFF, PNG, PDF) for automated document processing and smart data extraction.
    • Document Editor - The LEADTOOLS Document Editor is a zero-footprint document-editing solution for HTML5/JavaScript front ends with a Microsoft .NET (IIS & Kestrel), or Java (Linux/Apache) hosted back end. Developers can create robust, full-featured applications with rich document-editing capabilities, including text search, spell checking, undo/redo, copy, cut, paste, ruler, font styles, paragraph styles, and so much more! Formats supported include PDF, DOC/DOCX, and RTF.
    • Document Compare - The LEADTOOLS Document Compare SDK is an OEM-ready, zero-footprint document-comparison solution for HTML5/JavaScript front ends with a Microsoft .NET (IIS & Kestrel), or Java (Linux/Apache) hosted back end.
    • Document Converter - With LEADTOOLS Document Converter SDK libraries, developers can create powerful, automated document conversion, archival, and delivery systems.
    • Document Viewer - The LEADTOOLS Document Viewer SDK is an OEM-ready, document-viewing solution for .NET (C# & VB) and HTML5/JavaScript. Developers can create robust, full-featured applications with rich document-viewing features, including text search, annotation, memory-efficient paging, inertial scrolling, and vector display.
    • Document Writers - LEADTOOLS Document Writers libraries are a powerful and flexible development tool that converts a wide variety of document image sources into document formats such as PDF and PDF/A, XPS, ePUB and MOBI, ALTOXML, Microsoft Word (DOC/DOCX), Microsoft Excel (XLS), HTML, RTF, and Text.
  • OCR, MICR, OMR
    • OCR - Provides advanced preprocessing and document cleanup technology as well as the ability to handle both machine-printed and handwritten text with automatic detection and labeling of text, MICR E13-B or CMC7, MRZ, OMR, graphics, and table zones.
    • MICR - Create processes that automatically detect and extract MICR E-13B and CMC-7 text from personal and bank checks.
    • OMR - Provides fast and accurate Optical Mark Recognition SDK libraries to rapidly develop robust, high-performance recognition applications that detect whether boxes are checked and bubbles are filled within surveys and tests, saving time and money over manual data entry and inspection.
