Atalasoft DotImage OCR Module Add-On

by Atalasoft - Product Type: Component / ASP.NET WebForms / ASP.NET AJAX (ATLAS) / .NET WinForms / .NET Class / Managed/Unmanaged Code - without COM

Add OCR capabilities to your DotImage applications. Atalasoft DotImage OCR is an optical character recognition module for Microsoft .NET developers giving programmers the capability to add character recognition to their applications.  Atalasoft's approach to OCR is to provide an object oriented generic interface that can support any OCR engine.  This enables users of DotImage OCR to change OCR engines with a single line of code.  It's also convenient for testing and evaluating various OCR engines.  Atalasoft currently provides three OCR engine interfaces. Their own GlyphReader engine as well as Abbyy, and the royalty-free Tesseract engines.

What's new in Atalasoft DotImage 10.4 ?

Word Reader Add-on (for DotImage, any edition)
Customers have been asking to be able to open Microsoft Word files in Atalasoft's viewers. With this new product users will be able to rasterize basic word documents to save in other formats or display in the viewers.

Simply add the WordDecoder to the list of RegisteredDecoders. Any Word document opened with our controls would then become rasterized automatically and displayed in the viewer. The doc is turned into an AtalaImage that can be treated like many other formats that are supported.

  • Rasterizes (opens as an image) .doc and .docx files.
  • Allows Word files to be displayed in our viewers
  • Allows Word files to be converted to image formats that we support saving to.

PdfForm Support (for Atalasoft DotPdf SDK)
Interactive PDF forms can now be created, opened, and parsed for data. This is useful for creating digital interactions between your constituents and their clients. For example, a developer builds an app that created a PDF with form annotations, then sends that PDF to a user to be filled out. The user fills out the form and returns it. Lastly a service running DotPdf would open and parse the data and create any appropriate workflow objects.

  • Programmatically create new PDFs with fillable form data objects
  • Programmatically pre fill or customize forms on a per user basis
  • Programmatically read the data from a DotPdf form that has been filled in
  • Programmatically read the data from a preexisting PDF form that uses widget annotations for its form objects
  • Programmatically inject data into a form

PdfRepair (for Atalasoft DotImage Document Imaging or DotPdf)
Out of specification PDF files are fairly common. In this release Atalasoft have added the automatic faculty to correct some of the more common specification breaking issues. Now when opening a file with PdfDocument (Not PdfReader or PdfDecoder), if an issue exists in the PDF, the software will attempt to repair the issue before opening the file in PdfDocument.

More PDFs will open in PdfDocument without any code changes. In a situation where a user needs to care about how their malformed PDF is fixed they can subscribe to an event and make decisions as to whether or not the new fixed PDF has been fixed in a way that is satisfactory.

  • Automatically detect and repair common issues with out-of-specification PDF
  • Triggers an event if an issue is detected, so that it may be handled in a custom programmatic way
  • Improves general PDF consumption without any additional changes for a user.

Web Document Viewer Thumbnail Controls (for Atalasoft DotImage Document Imaging edition or Atalasoft JoltImage)
Atalasoft's legacy web controls had an image viewer and a thumbnail viewer to navigate multipage documents. With the 10.4 release, the newer Web Document Viewer controls now have a thumbnail control that can be used alongside the image viewer.

Navigate through multipage PDF or TIFF documents in the browser with this linked thumbnail control.

  • Connects to the Web Document Viewer for quick page-viewing control
  • Server backends for both Java and .NET environments
  • Displays annotations made in the main viewer

SharePoint WebParts (for Atalasoft WingScan or DotImage Document Imaging)
Hosting the WebDocumentViewer or WingScan WebCapture control in SharePoint was difficult for customers. In this release, there is a simple SharePoint WebPart that allows users to easily add the WebPart to their SharePoint deployment and have it display on their SharePoint pages.

Add the WebPart controls to the list of WebParts that users can add to their pages. The users can then create pages in SharePoint with the WebDocumentViewer or WingScan WebCapture web controls and they will interact with SharePoint document lists.

  • Simplifies full trust deployments of WebDocumentViewer and WingScan WebCapture controls (supports all of our supported image formats)
