LEADTOOLS Raster Pro, Document, and Medical Imaging Toolkit Features

Raster Imaging Pro SDK:

LEADTOOLS Raster Imaging Pro provides win32 and x64 support for adding the capability to display, load, save, convert or process images to any application. The toolkit supports Color Conversion, Display, and Compression (JPEG, JPEG 2000 [read], TIFF, CCITT G4 and LEAD's proprietary CMP). Developers get support for all of the technologies found in the LEADTOOLS Raster Imaging Engine, including Image Processing (Transforms, Filters, Drawing, Region of Interest), TWAIN Scanning (32-bit), Color Conversion, Display, Special Effects, (choose from more than 2000 effects), Compression, Image Format support (150+), Printing, Internet/intranet imaging, Database imaging, Imaging Common Dialogs, and Screen Capture.

In addition, LEADTOOLS Raster Imaging Pro offers the ability to directly call exported DLL functions, create extremely small footprint applications, obtain low-level access to pixel data, create custom image processing filters, exert full control over load/process/save with callbacks, share images (without copying) via DIBs/DDBs, exert full control over all display options, and support the extended FlashPix file format capabilities.

Document and Medical Imaging Toolkits:

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 SDK

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

Special functions for Document (bitonal) images. The LEADTOOLS functions for bitonal images are especially useful for working with images from black-and-white scanners or FAX machines. These functions let you do things such as automatically straighten (deskew) an image, remove spots (despeckle), or clarify a scaled display (using scale-to-gray and favor-black features).

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.

Fast rotation. LEADTOOLS achieves fast rotation in 90-degree increments by applying a rotated view perspective to the bitmap.

FAST TWAIN support (32-bit). 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.

Faster compression and decompression. The Document/Medical editions work faster when loading and saving LEAD CMP, JPEG, and CCITT Group 3 and Group 4 images. The LEADTOOLS functions for loading and saving are the same in all products. The only difference is in performance.

1-bit Image Clean-up. The Document toolkits include support for removing dots, blobs, holes, inverted text, lines, borders, bumps and nicks from 1-bit images.

Region Clean-up. [Document/Medical] Remove all the holes from a region.

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. [Document/Medical] Load, process, display, window level and save 12 and 16 bit grayscale images (including support for 16-bit grayscale TIFF).

MRC Support. [Document/Medical] LEADTOOLS supports the Mixed Raster Content format for color documents containing mixed image and text components.

ABIC. Read and write ABIC compressed files.

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

The LEADTOOLS Document Imaging Suite toolkit builds on the capabilities of LEADTOOLS Document Imaging, adding key OCR and JBIG features:.

OCR features. [Document/Medical] LEADTOOLS OCR features, built with Nuance Textbridge technology, allow you to perform optical character recognition and turn images into documents. 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.

Recognized text can be exported to more than 150 different formats, including MS Word, MS Excel, Dbase and WordPerfect. The LEADTOOLS OCR features contain superior OCR processing speeds, for use in form recognition and processing applications.

LEAD's JBIG filter. [Document/Medical] 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.

LEADTOOLS Medical Imaging SDK
