Document Imaging SDKs LEADTOOLS Document Products Overview

There have been some changes in version 15, Click here to see what's new

LEADTOOLS Document Imaging toolkits include comprehensive annotations, specialized bitonal image display and processing, image clean-up, high-speed scanning, OCR/ICR/OMR (character, hand-print and form processing), barcode recognition and much more.

With buzzwords and phrases like "paperless office", "document archiving" and "electronic file cabinet", your clients are asking for more sophisticated and specific document imaging functionality to be included in your applications. LEADTOOLS' Document Imaging product line builds from LEADTOOLS' Raster Imaging technology to add features specifically for black and white imaging with the best possible performance.

LEAD Technologies provides two document imaging SDKs and several plug-ins for your document imaging development.

Developer Toolkits

• LEADTOOLS Document Imaging SDK Includes everything you need to create high performance applications specifically for the document imaging vertical market. Includes Win32 API, C++ Class Libraries, .NET Class Libraries and COM.
• LEADTOOLS Document Imaging Suite SDK LEADTOOLS Document Imaging toolkit with OCR support. Includes Win32 API, C++ Class Libraries, .NET Class Libraries and COM.

Add-ons

• LEADTOOLS OCR Module - Allows you to easily include code in your applications to perform character recognition on document files.
• PDF OCR Plug-in - Adds PDF output support to LEADTOOLS OCR.
• LEADTOOLS OMR Module - Process forms with checkmarks, bubble sheets, etc.
• LEADTOOLS ICR Module - Process handwritten documents and forms.
• LEADTOOLS Barcode Modules - Allows you to read and write Linear (1D), DataMatrix (2D), PDF417 (2D) and QR Code barcodes with support for 95 different sub-types.
• LEADTOOLS ABC Plug-in - Advanced Bitonal Compression - Read/write files with LEAD’s proprietary ABC compression. LEADTOOLS ABC compression is superior to JBIG2, LZW, TIFF Group 4 and other 1 bit compression.
• LEADTOOLS NITF Plug-in - Provides functions that enable you to manipulate the NITF (National Imagery Transmission Format Standard) file format in your Windows applications.
• LEADTOOLS WPF Module - Add WPF support to LEADTOOLS Raster Imaging Pro v15 and up. Includes Bitmap Effects, WIC Codecs, and WPF Image Viewer and ImageList Controls.

Summary of LEADTOOLS Document Imaging Technology

LEADTOOLS Document Imaging: specialized technology optimized for use with bitonal (2-color or black/white) images such as scanned text documents, line art or technical drawings. Includes Annotations (document mark-up), high-speed scanning, OCR (Optical Character Recognition), ICR***, OMR*** and Barcode Recognition**.

LEAD's Document Imaging functionality includes:

Document Clean-up

Removal of unwanted elements of scanned documents, including:

• Border removal
• Dot removal
• Hole-punch removal
• Line removal
• Smoothing
• Text inversion
• Specialized Bitonal Filters - specialized image processing filters, including despeckle (remove noise), deskew (rotate to align with horizontal), erosion (thin), dilation (widen) and specialized display filters including favor black (don't lose black pixels when scaling) and scale to gray (blend black and white pixels when scaling), which allow you to enhance bitonal images.

Annotations

Document Markup including the following types of fully automated annotations:

• Line
• Rectangle
• Ellipse
• Polyline
• Polygon
• Curve
• Closed Curve
• Pointer / Arrow
• Freehand Scribble
• Text
• Rich Text
• Text with Pointer
• Note
• Stamp
• Rubberstamp
• Hotspot
• Freehand Hotspot
• Button
• Point
• Highlight
• Pushpin
• Ruler
• PolyRuler
• Protractor
• Cross Product
• Redact / Blackout
• Encrypt / Decrypt
• Audio
• Video (capture and playback)
• User Definable

Annotations include design/run/disable modes, right-click context menus, automatic annotations toolbar, multilayer security features and much more.

OCR*

Optical Character Recognition. LEADTOOLS includes the following functionality:

• Manage multiple pages of a document at one time where the different pages are in different stages of processing (segmentation vs. recognition), and you can recognize all document pages at once.
• Recognize a document page(s) and export text in raw format or a ScanSoft defined mark-up language format (XDoc/XDoc Lite), the raw formats include ISO and UNICODE.
• Automatically segment the page to correctly recognize text on pages with complex or irregular layouts, including tables, reverse video, and line art as well.
• Process both text and graphics, providing the basis of a compound document processing system.
• Process documents in two-page mode for open-faced books and magazines.
• Documents with multiple languages.
• Enable end users to verify or correct text during the recognition process.
• Automatically detect fax, dot matrix and other degraded documents and compensate accordingly.
• Process images from newspapers with special image processing designed for newsprint.
• And more...

OMR ***

Process forms with checks or bubble sheets, etc... An OCR Module add-on.

ICR ***

Recognize hand-written text, forms and documents. An OCR Module add-on.

High Performance Memory Optimizations

Documents scanned at high dpi can take up huge amounts of memory when uncompressed. LEADTOOLS Document Imaging Engine stores 1-bit and 24 bit images compressed in memory, uncompressing portions as needed for display and processing, enhancing real-time performance. Additionally, large images that need to be loaded for viewing can be resized to greatly reduce the memory overhead of keeping the extra image data in memory.

TWAIN Scanning

Control scanning and capture devices that use readily available TWAIN drivers.

JBIG

JBIG progressive image compression/decompression capabilities.

Mixed Raster Content

Provides optimal compression for documents that have both text and color images in the same file.

Barcode Recognition ****

Add-on support for reading and writing Linear (1D), DataMatrix (2D), PDF417 (2D) and QR (2D) barcodes.

ABIC

Read and write ABIC files to compress check images.

JBIG2

Read and write files with JBIG2 compression.

LEADTOOLS ABC **

Advanced Bitonal Compression is an add-on module for reading and writing LEAD's proprietary ABC Compression.

* OCR available with Document Imaging Suite or for purchase as an add-on to the Document Imaging, Medical Imaging and Medical Imaging Suite.

** Available for purchase as add-ons to any LEADTOOLS Document or LEADTOOLS Medical Imaging toolkit.

*** ICR and OMR are available as add-ons to the LEADTOOLS OCR module or the LEADTOOLS Document Imaging Suite.

****Barcode Modules add on to all Raster, Document, Medical and Vector toolkits.
