I am using v15, when reading text it reading “8” as “3”
Please try setting some of the OCR properties. For instance, you can set a searchRectangle to tell the OCR where on the screen to read or look for text, and you can also set the Contrast to ON and then choose a contrastColor to help clear up any anti-aliasing that may be making the characters difficult to read.
You can read about all of the most common OCR properties here: http://docs.testplant.com/?q=content/working-ocr
If you’re still having trouble, please write in to support and send a full-resolution screenshot of the SUT showing the text in question, along with the line of code you’re using to read the text.
