Below is the procedure to read text from an Image. Since your text appears straightforward you may be able to get the characters, else Captchas are not easily readable if they are complexly structured.
- Spy the portion of the area that contains the Captcha in Region Mode
- Use a Reader stage for the spied element
- In the actions dropdown choose Read Text with OCR
- This will return the text from the image into a Data Item.
If the data item is blank, then the area spied is not appropriate and you may need to re-spy it (or do it multiple times) until you find the correct Region.
