Get text from screen in sikuli using offset

Use this:

find("img.png").right(100).text()

to extract the text that is in the area on the right of your image, with width 100px.
You can also use left(), below() or above() to search in other directions.

Be aware that text recognition is in many cases not precise.

Addition:
of course you have to assign the result to a variable, so it's

foundText = find("img.png").right(100).text()

And you should use foundText = foundText.strip() afterwards to get rid of any unwanted leading or trailing white spaces.

I integrated Selenium with Sikuli and I'm trying to get text from an image but I'm not able to fetch. Here is my code.

  String text = screen.find( ".//SikuliSnapshots//HBOGO//Preview.png";).text();
  String Finaltext = text.trim();
  System.out.println(Finaltext);

Text is always null.

*** Text is always null.
I guess you mean "empty", since the sequence (the extra ; is a typo???)
screen.find( ".//SikuliSnapshots//HBOGO//Preview.png").text();

should either throw a FindFailed or return a string (which might contain only whitespace), but never Java null.

If I am right, then the given text simply cannot be read with the current Sikuli X (there are many problems with OCR).

I have integrated sikuli with open script and I am also applying the same Code for capturing the text from application but its giving an error as :

String foundText;
foundText = find("img.png").right(100).text();

The method find(String) is undefined for the type script

The above error is resolved but while running i am getting this error.

OrderNumber.png looks like a file, but can't be found on the disk. Assume it's text.
