Atalasoft DotImage .NET Imaging SDK v11.0.0.10 Build 507

Atalasoft’s DotImage SDK provides robust viewing technology for captured documents. Scan, view, convert, edit, annotate, and transform paper and electronic documents in your desktop and web applications. TWAIN (Technology Without an Interesting Name) is a scanning driver communication specification standard used for writing device drivers for scanner agnostic applications.

Atalasoft DotTwain is a .NET SDK for capturing digital images from scanners, cameras, and other TWAIN devices. It uses the latest TWAIN specifications for ultra fast scanning.

DotTwain can be used in a small footprint web deployment delivered as a .NET “no-touch” or signed ActiveX. Or it can be used in a standalone .NET scanning solution. DotTwain supports 32- and 64-bit TWAIN 1.x/2.X drivers and is included in DotImage Document Imaging.

Atalasoft’s WebDocumentViewer (WDV) controls let you embed a full document viewer with thumbnails and controls within a web browser to:
Open any DotImage supported image type (add-ons too)
View and print from any repository of documents.
Markup the document with annotations
Redact content on the document by burning annotations
Edit, Insert, Reorder, Remove, or Rotate pages
Cleanup documents using binarize, deskew, despeckle, and all other DotImage ImageCommands
Capture from a client connected scanner with WingScan

Microsoft Office Reader
Microsoft Office Decoder (Word/Excel/PowerPoint) is an add-on to DotImage.
This add-on quickly decodes Word, Powerpoint, and Excel documents into color or grayscale raster images, seamlessly plugging into DotImage and associated image viewing components as an image decoder.

Convert Office files to raster images in Atalasoft image viewer controls:
See a full list of supported formats
Use the OfficeDecoder class if you need fast rendering. Results aren’t 100% accurate, but there’s no requirement for Office to be installed and no security concerns.
Use the OfficeAdapterDecoder class if you need 100% accuracy. You will need an instance of the required Office application on your server and macros can represent a security threat.
Print Documents using the DotImage Printing components or by rendering onto a printer graphics object.
Convert Documents into any supported DotImage image format (multipage TIFF, JPEG, etc).
Integrates with our AJAX enabled Web Image viewer for server-side viewing, panning, and zooming of documents

OCR, or Optical Character Recognition, is a process to locate and identify typed letters in an image. ICR or Intelligent Character Recognition is a process similar to OCR but it is used to identify hand-printed letters in an image. Our toolkit allows OCR and ICR engines to be implemented by extending our base OcrEngine class. The Recognize() method is used to start the process. Additionally, we have partnerships with the following OCR and ICR engines and provide the OcrEngine class overload out of the box:

Start your engines

Multipage documents can be very large when fully loaded into pixel memory. To work with this, we provide:

Classes to change the pages in a document without loading them into memory.
These are useful for removing, rearranging, and adding pages to an existing document with minimal overhead.

Combine static method for quick combining of PDF documents
PdfDocument.Pages collection contains PdfPage objects that allows pages to be added, removed and rearranged
PdfPage.Frame can be used with the PdfDecoder object to open the page into an AtalaImage.

OMR, or Optical Mark Recognition, is commonly used to transform documents with marks into contextual data.

Typical uses include, bubble sheet reading, reading form areas, and survey data extraction.

The process starts with alignment. During alignment a base template image is compared to a scanned image and it is lined up using landmarks on the document. Once this is complete the templates defined areas can be read from.

The following classes can be customized or used to create a custom OMR workflow:
DocumentAligner – Our base document aligner. Does the transformation to a document to match to a template. Can be replaced with custom code using IDocumentAligner.
DocumentRejector – Our base document rejector. Determines whether a document is matched or not. Can be replaced with custom code using IDocumentRejector.
OmrTemplateDocument – Used to define the template. Use code to define target areas and mark areas on a document. This will be used for matching and detecting marks.
OmrDocument – Used for the scanned multipage image to be compared to a template.
OmrPage – Represents a single scanned page.
OmrMark – The structured class to look at a mark area and what the determined result was.

DICOM Format – This format is included with DotImage
Create a medical imaging application for displaying X-Ray DICOM images, a tablet application for doctors to diagnose an image and annotate freehand notes on a separate layer, or build an application to read patient information embedded in a DICOM image. DICOM is included with Atalasoft DotImage.
