  • OmniPage Server accurately digitizes, converts and compresses files in your document archives at scale.

Optical Character Recognition.

OCR is a method by which software "reads" the text characters to preform text recognition from an otherwise flat, scanned image. The resulting text can be placed anywhere programmatically and is necessary in larger document workflows and for discoverability.

Intelligent Character Recognition.

ICR follows the same software concept but is tuned to recognize hand printed rather than computer printed text. To do ICR you need to clearly define the areas that need to be recognized, text should be in block caps only with framing.

HTML5 Web and Mobile Viewing.

Web and Mobile viewing of TIFF, PDF, DICOM, JPEG200, JBIG2, Word, Excel, PowerPoint and many other formats. You can open any DotImage supported image type, view and print from any repository of documents, markup the document with annotations, capture from a connected scanner, Edit, Insert, Reorder, Remove, or Rotate pages, and Cleanup documents using binarize, deskew and despeckle to name a few.  We have controls for WinForms, ASP.NET, ASP.NET MVC, Silverlight, and WPF. Whether you need a thumbnail view of the pages of a document or a standards-compliant annotation authoring and editing toolkit, DotImage has a control for your application.

PDF: View, Edit, and Create.

Add PDF to your desktop or web application.  If you need to view a PDF, convert another format to a PDF, manipulate the pages of a PDF, or read or write PDF meta-data or bookmarks, you just need DotImage, Adobe Reader is not required. With DotImage you can view and annotate a PDF in any of our controls. PDF/A and encrypted PDF are supported, and if you need to create a searchable PDF, you just need to add an OCR engine and you can create a two-layer PDF with the original image and recognized text.

OCR and Searchable PDF.

Hello papa we will add some info here on tesseracy and other OCR Engine options.


Quickly add annotation support to your desktop or web application.  Redact sensitive information, highlight critical information, create custom annotations, visual signatures, or text notes.  Out of the box viewing, printing, burning, and editing of images with annotations.  Support for Freehand, Text box, Sticky note, Rubber Stamp, Custom images, Signature, Redactions, Shapes, Line, Ellipse, Rectangle and polygons.  Built-in support for annotating multipage documents such as multi-page TIFFs.  View and Author PDF Annotations without requiring Adobe Acrobat.  Print images with annotations exactly as they appear in the viewer.

Format Conversion.

DotImage can be used as the basis for the image or PDF conversion features of your application. Using DotImage you can read or write PDF, TIFF, PNG, JPEG, and many other common image formats. For specialty applications like medical imaging or engineering, we can read and convert DICOM, DWG, or DXF. We are also compatible with the .NET Bitmap class.

Image Processing.

DotImage can perform any basic image processing function like crop, rotate, flip, resize, or resample. We can also do things that you might find only in an imaging toolkit, like complex overlays, noise addition and reduction, color management, or auto-leveling. And, we have extremely advanced photo and document processing like our fast (patented) Deskew algorithm, despeckle, border/line/hole-punch removal, and much more.

Manipulate multi-page formats.

For TIFF and PDF files, we support reordering, removing, adding, replacing, and combining pages to create new files. Use it to split documents, replace individual pages with cleaned up versions, combine multiple documents, remove blank or redacted pages, or anything you need to do to make the specific document you need.


Image files have more than pixels, and using DotImage you can read and manipulate the metadata of your image and PDF files, including EXIF and IPTC.
