This C# DotNet demo uses the LEADTOOLS v16 DotNet interface to illustrate the use of the OCR engines(Advantage, Plus, & Pro) available in the SDK. This demo shows how to search a document for specific words and highlight them with an appropriate color. This demo also allows the user to simply OCR a document and save a searchable PDF. Note: The documents created are either a searchable PDF or a 24-bit TIF file with highlighting. They cannot be combined.
Quick start guide:
1.) When you start up the demo, begin by selecting the engine you want to use. The default is the Plus engine (Engines -> Plus)
2.) Load a document (File -> Open).
3.) Recognize the document (Actions -> Recognize)
4.) Set the words to highlight (Actions -> Set Highlight Words). When the dialog appears, enter the words to highlight in the list. If you intend to use this list again, you can save it for later (File -> Save Words File). Set the highlight color (Color -> Select Highlight Color).
5.) Highlight the words in the document (Actions -> Highlight). Note: This will convert the image to 24-bits if it is not already.
6.) Save the resulting image (Actions -> Save Results).

This demo has been updated to us VS 2010 using the LEADTOOLS v17 dlls. The project has been updated to allow for also selecting to use the new OCR Arabic engine. A few other minor changes were necessary in the code as well to use the LeadRect and LeadPoint structures.

This demo has been updated to use LEADTOOLS v17.5. The rest is almost identical to the post for LEADTOOLS v17.0.

This demo has been updated to use LEADTOOLS v20, the .NET framework 4.0, and Visual Studio 2015. Updates have been made to now use the LEAD and OmniPage engines. To use this demo, extract it to its own folder in "C:\LEADTOOLS 20\Examples\DotNet\CS".
