  • FAST TWAIN support (32-bit). Control image acquisition from any device (scanner, digital camera, etc) which supports TWAIN. Use device's built in user-interface or create your own. Analyze the TWAIN source, considering the bits per pixel, image type and compression requested from the TWAIN device, and find the fastest compression type, transfer mode and buffer schemes to get the best performance possible.
  • Screen Capture. LEADTOOLS provides functions for capturing all or part of the screen. The result can then be used with any of the LEADTOOLS image processing functions and can be saved in any file format that LEAD supports.
  • Printing. Print images or selected regions while controlling position/scaling, halftoning/dithering.Print multiple images and text to a single or multiple pages.
  • Common Dialogs. Imaging Common Dialogs provide a set of common dialog boxes that combine Windows Common Dialog functionality with LEADTOOLS imaging functionality. The following namespaces support common dialogs:
  • Database Imaging. Store images (any supported file-format/compression-technique) to a variety of databases, including SQL, Oracle or any database which supports ODBC, OLE DB, or that can be bound via VB data control connections. The following namespaces/classes support database imaging:
    • Leadtools.Codecs. Support includes palettes, memory files, multi-page files, compressed files, comments, tags, animations, view perspectives, raw image data, compressed data, alpha channel.
    • The RasterImageViewer control. The RasterImageViewer control supports databinding, a fast, easy way to connect to databases. All LEADTOOLS filters have databinding support for loading and saving.
  • Internet. Includes functions to load images from URLs or memory streams. LEADTOOLS products can be used to extend functionality on a server or in Internet Explorer.
  • Barcode Modules. LEADTOOLS Barcode Module functions allow you to read barcodes, write barcodes and find duplicate barcodes within an image. Barcode modules allow programmers to easily integrate the ability to read and write barcode symbols into their applications.

Document/Medical:

Building on LEADTOOLS core Raster Imaging functions, the LEADTOOLS Document Imaging, LEADTOOLS Document Imaging Suite, LEADTOOLS Medical Imaging and LEADTOOLS Medical Imaging Suite are the most comprehensive imaging toolkits on the market. No other toolkit provides as many imaging features for color, gray-scale and black & white images in one development package, and for one price. These toolkits comprise LEAD's best code and are designed for the programmer who is looking for the fastest performance, and/or the most extensive color, document, and medical imaging capabilities available.

These toolkits contain powerful annotation capabilities, optimized document image processing filters, and high performance compression, decompression and viewing of ABIC, CMW wavelet, JBIG/JBIG2, JPEG, JPEG 2000 (read/write), LEAD CMP, LEAD ABC (bitonal), and CCITT G3/G4 file formats. The annotation capabilities enable the programmer to add text, highlights, sticky notes, audio, ellipses, buttons, lines, arrows, rectangles, polygons, redaction (blackout), hotspots, freehand scribble, pointers, bitmap and text stamps, to black & white and color images. Programmers working with document imaging will also find special processing filters such as despeckle, deskew, favor black, and scale to gray to enhance their black and white 1 bit images. Additionally, you can achieve faster rotation in 90-degree increments by applying a rotated view perspective to the bitmap. These LEADTOOLS toolkits offer the fastest software-only JPEG decoder available.

[Document/Medical] is used throughout the help files to designate the features that are available in LEADTOOLS Document Imaging, LEADTOOLS Document Imaging Suite, LEADTOOLS Medical Imaging and LEADTOOLS Medical Imaging Suite. Those features that are available only in the Medical toolkits are indicated by (Medical). Features available only in the LEADTOOLS Medical Imaging Suite toolkit are indicated by (Medical Suite).

LEADTOOLS Document Imaging

The LEADTOOLS Document Imaging toolkit contains all the features available in the LEADTOOLS Raster Imaging Pro. In addition, it contains the following capabilities:

  • Annotation. LEADTOOLS supports annotation of images by letting you overlay images with text, lines, shapes, arrows, buttons, highlights, hot spots, sticky notes, stamps, buttons, and sounds.
  • Bitonal Scaling (Image Enhancement) for black-and-white images. LEADTOOLS functions for bitonal images greatly enhance their on-screen quality and readability. These functions are especially useful for working with images from black-and-white scanners or FAX machines.
  • Document Cleanup (Image Enhancement) for bitonal images. Other LEADTOOLS functions for bitonal images (especially useful for working with images from black-and-white scanners or FAX machines) let you do things such as automatically straighten (deskew) an image (ncluding proprietary functions for deskewing scanned bank checks), remove spots (despeckle), or clarify a scaled display (using scale-to-gray and favor-black features). Document toolkits also include support for removing dots, blobs, holes (holepunch marks), inverted text, lines, borders, bumps and nicks from 1-bit images.
  • Fast rotation. LEADTOOLS achieves fast rotation in 90-degree increments by applying a rotated view perspective to the bitmap.
  • Embedded Messages. The Document toolkits include support for embedding messages in lossless image formats like BMP, TIFF, lossless JPEG, etc. The message is embedded without any visible changes to the image, and does not appreciably increase the size of the image. The message is password-protected.
  • 12 and 16 bit grayscale images. Load, process, display, window level and save 12 and 16 bit grayscale images (including support for 16-bit grayscale TIFF).
  • ABIC. Read and write ABIC compressed files (used for compressing bank check images).
  • JBIG filter. LEAD includes support for this filter in the LEADTOOLS Document and Medical Imaging toolkits. JBIG defines a method for lossless compression encoding of a bi-level image (two-color image). This method can also be used for coding grayscale and color images. LEADTOOLS completely supports all three types of images, giving you the ability to make full use of this powerful compression technology. LEADTOOLS also supports the progressive capability of JBIG, allowing you to store and send multiple representations of images at different resolutions without any extra storage overhead.
  • MRC Support. LEADTOOLS supports the Mixed Raster Content format for color documents containing mixed image and text components.
  • Raster PDF Save. Support for saving raster images as a PDF file. This includes the Advanced PDF save and compression features.

LEADTOOLS Document Imaging Suite

OCR support is included in the LEADTOOLS Document Imaging Suite, or can be added as a plug-in to the LEADTOOLS Document Imaging, LEADTOOLS Medical Imaging and LEADTOOLS Medical Imaging Suite toolkits.

    Features include preset confidence and accuracy levels for controlling how sensitive the engine is to unrecognized text, artificial intelligence for improving recognition on documents of the same type, and built-in plus user-defined lexicons for limiting the type of text to recognize within a particular zone, as well as the ability to verify or correct text during recognition. The OCR engine can perform Automatic area segmentation creating multi-layered zones, recognizing areas such as tables, rules, images and text. Or, you can manually designate up to 250 such zones. Different fonts, font sizes (5 to 72 point), and styles are also supported. Fax, dot matrix and halftones can be preprocessed to improve recognition results. The OCR Engine supports major European and Scandinavian languages (Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish) as well as English. Support for dialects such as US. English, French Canadian, Latin American Spanish, Swiss German, and Brazilian Portuguese is also provided.
