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 them by calling L_UnlockSupport(L_SUPPORT_LTPRO, L_KEY_LTPRO). L_KEY_LTPRO can be found in ltkey.h.
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 L_UnlockSupport.
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.
Image Conversion.
The Document toolkits include support for transforming a bitmap
into a binary image using specified thresholds or a threshold calculated
automatically based on statistical features of the bitmap.
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 for color documents containing mixed image and text components.
Halftoning.
[Document/Medical] Convert 1-, 4-, 8-, 16-, 24-, or 32-bit bitmaps
to a halftoned bitmap, with a specified pattern rotation. A halftoned
bitmap is a 1-bit bitmap that has been dithered for black and white printing
or display.
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 text during, and (using LEAD's unique
OCR editor) after recognition. LEAD's OCR editor ties the text being edited
directly to the image, providing a visual reference to the original bitmap
data. 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.
