Raster Pro/Document/Medical Features

Raster Pro:

LEADTOOLS Raster Imaging Pro provides some imaging capabilities that are not available in the LEADTOOLS Raster Imaging product. In order to access these features, you must unlock support for L_SUPPORT_LTPRO, using the UnlockSupport method. L_KEY_LTPRO can be found in LTLckKey.inc.

If you are a licensed user of LEADTOOLS Raster Imaging, and would like to access Raster Imaging Pro features, you must contact Tech Support for information on obtaining a license and the unlock key for calling UnlockSupport method.

Document/Medical:

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 and optimized document image processing filters, and high performance compression, decompression and viewing of JPEG, LEAD CMP, MRC and CCITT G3/G4. 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.

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:

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.

ISIS support. LEADTOOLS supports ISIS interfaces for driving scanning devices.

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).

48 and 64 bit color images. [Document/Medical] Load, process, display, and save 48 and 64 bit color images.

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

LEADTOOLS Document Imaging Suite

The LEADTOOLS Document Imaging Suite toolkit contains all the capabilities of LEADTOOLS Document Imaging, and includes the features listed below. Please note that the OCR features are included in this toolkit, however they can also be purchased as a plug-in for the LEADTOOLS Document Imaging toolkit. Also, JBIG support is provided in this toolkit, however a JBIG Module may be added on to LEADTOOLS Document Imaging, LEADTOOLS Medical Imaging or LEADTOOLS Medical Imaging Suite.

OCR features. [Document/Medical] LEAD offers OCR features that use Scansoft Textbridge technology. Support for these features is included in the LEADTOOLS Document Imaging Suite, and can be added, via plug-in to the LEADTOOLS Document Imaging, LEADTOOLS Medical Imaging and LEADTOOLS Medical Imaging Suite toolkits. The OCR features allow you to perform optical character recognition and turn images into documents. 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 and user-defined lexicons for limiting the type of text to recognize within a particular zone. LEADTOOLS provides the ability to verify or correct the 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. The OCR features support different fonts, sizes (5 to 72 point) and styles. 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 40 different formats, including MS Word, MS Excel, Dbase andWordPerfect. 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 Imaging Suite toolkit. Support for this filter can be added to LEADTOOLS Document Imaging, LEADTOOLS Medical Imaging or LEADTOOLS Medical Imaging Suite by purchasing the JBIG Module. 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

LEADTOOLS Medical Imaging contains all the capabilities of LEADTOOLS Document Imaging. It also includes general medical imaging technologies (1-16,24,32 bit color, 1-16 bit grayscale and window leveling of 12 and 16-bit grayscale images) and support for the DICOM file format.

DICOM file support. [Medical] LEADTOOLS Medical Imaging provides COMPLETE support for the DICOM 3.0 specification, including all standard IOD classes and modalities (CR, CT, MR, NM, US, RF, SC, VL, etc.) and complete DICOM Basic Directory support.

Window leveling. [Document/Medical] Detect and set LowBit and HighBit for image data, display images with automatic LUT intensity expansion, or set LUT entries and ranges with specific values and gradients. Display images through the LUT without changing the data, or process the image data using the LUT. Linearize the number of pixels locally in a bitmap, based on the specified color space in order to bring out the detail in dark areas of an image, and smooth the edges between blocks.

Medical Imaging Processing. [Medical] LEADTOOLS Medical Imaging provides image processing functionality designed specifically to allow you to examine and improve the quality of medical images.
