Attached is a sample project using C# and Leadtools 18. This project shows how to use the AutoZoning Image Processing Command to generate zones for an image to be used in OCR.
http://www.leadtools.com/help/leadtools/v18/dh/po/leadtools.imageprocessing.core~leadtools.imageprocessing.core.autozoningcommand.html
The AutoZoning command lets you choose various options for the process and can be seen here:

Also shown in this demo is how to draw rectangle annotations using the new Leadtools.Annotations.Core namespace based on the zones.

Hi hadi,
I get an error " 'IOcrPage' does not contain a definition for 'RecognizeText' " after importing the project in VS 2015.
what have to do ?
error message:
Severity Code Description Project File Line Suppression State
Error CS1061 'IOcrPage' does not contain a definition for 'RecognizeText' and no extension method 'RecognizeText' accepting a first argument of type 'IOcrPage' could be found (are you missing a using directive or an assembly reference?)

The issue you are seeing is because the example was built using version 18 of the LEADTOOLS SDK.
I have updated the project to work with version 19, please download and use this one.
