You would really need to ask a more specific question if you want to
have any hope of an answer.

If you mean you want to select an area of an image and have only that
piece be sent for OCR then the usual way to do that is to make a copy
of that selection and use that instead of the whole image.

Here more details about requirement:
The scanned document has some of the important texts in specific
color highlighted, i need to get those text separately. It is not
possible to pass those highlighted text image part to do ocr alone.

Thanks

that is really an image processing problem -- you would need to find an image process that eliminates all but the highlighted text and supply that image to tesseract as black and white (binary).

SR, were you able to find a solution for your problem? To OCR just a highlighted text?
