When you want to read any document or data in a specific area on the screen with OCR, a field definition is required.  
For this definition, x, y, w, h components are used.  
**Step1.** The screenshot of the relevant file or screen is taken.  
**Step2.** The screenshot opens with Paint. (Will not open with Paint 3D)  
**Step3.** As in the sample screenshot, click the Select button in Paint.  
**Step4.** While the area to be read is selected, the expressions in the lower left corner of Paint are noted.

_If the noted values are to be read from the document, they can be added to the x, y, w and h fields in the Read as text component under OCR; If it is to be read from the screen, it is written in the x, y, w and h field of Screen ocr scan under OCR._
