 +Twain application which is used to communicate with the scanner application. You can download the toolkit  
 +from here http://www.twain.org/devfiles/twainkit.exe 
 + 
 +== How to set up == 
 + 
 +The user have to include all the necessary libraries and the header files which were mentioned above,  
 +to the working directory. 
 + 
 +Then you can run the SahanaOCRUI exe or run the project using the Visual Studio.  
 + 
 +== procedure ==       
 + 
 +Here is the link for a video guide  
 + 
 +when you run the project you can see the initialize window of the project.  
 +{{:foundation:3.jpg|}} 
 + 
 +It contains select boxes for  
 +  
 +  * choosing the scanner 
 +  * choosing the images from the file system 
 +  * choosing the Xforms from the file system 
 + 
 +So initially the user can select whether he is using the images from the file system or form the 
 +feed the images by scanning from the scanners, by selecting the check box available in the initialize 
 +form. Then if you select scanner you wanted to select the corresponding xform for it. For the scanner  
 +there are two options to configure the scanner and to test the scanners.  
 + 
 +By the configure option we can configure the scanner settings.  
 +{{:foundation:4.jpg|}} 
 + 
 +The Test option provide you a chance to check whether the scanner is correctly working with the application 
 +and is it scanning correctly.  
 +{{:wiki:user:preview.jpg|}} 
 + 
 +By the Test it scans the image and show it on the preview window as above.  
 + 
 + 
 +Or else you can select the image and the corresponding Xform for it. Then after submitting those images the  
 +system direct you to the main form of the application.  
 + 
 +The process window is as follows.  
 +{{:foundation:5.jpg|{{:foundation:5.jpg|}}}} 
 + 
 +If you are using the images from the file system, you can see the image you have submit to the system at the  
 +main form. Or else there is a option to scan the images from the scanners. 
 + 
 +After that you can start the process of form processing and the system directs you to the Log form which shows  
 +process of the form.  
 +{{:foundation:logform_modified.jpg|}} 
 + 
 +At the Log window there is a image box that updates the segmented current letter box of the form. And there also 
 +a text box that shows the corresponding recognized letter during the process.  
 + 
 +There is a text area in the Log form that shows the results of the data fields during the process.  
 + 
 +== Conclusion == 
 + 
 +These are the basic functions of the SahanaOCR project.
