====== OCR Condition ======

The //OCR condition// (v9.0+) extracts the text from an image using OCR (Optical Character Recognition) (specifically using Apple Text Recognition (v11+ and macOS 10.15+) or the [[https://en.wikipedia.org/wiki/Tesseract_(software)|Tesseract OCR library]]) and determines if it currently meets the specified.

The source image can be pasted  into the action, or read from the System Clipboard, Trigger Clipboard, a Named Clipboard, or a file, or you can get the image from the screen.

When reading from the screen, you can get the image from all screens, or from a specific screen or window or area on the screen.

You can choose what language or script the text is in.  Each language will require a download, typically between 1 and 10 MB, though there are a few scripts that are significantly larger.

You select the _comparison criteria_ in the popup menu.

^ PopUp Item ^ Description ^
^ is empty | does not contain any. |
^ is not empty | contains some text. |
^ is | has text that exactly matches a specified string. |
^ is not | does not have text that exactly matches a specified string. |
^ contains | has text that contains (case insensitively) a specified string. |
^ does not contain | does not have text that contains (case insensitively) a specified string. |
^ starts with | has text that starts with (case insensitively) a specified string. |
^ ends with | has text that ends with (case insensitively) a specified string. |
^ is before | has text that is alphabetically before a specified string. |
^ is after | has text that is alphabetically after a specified string. |
^ matches | has text that matches a specified regular expression. |
^ does not match | does not have text that matches a specified regular expression. |

As with any OCR, the text may contain errors so you should be relatively liberal in how specifying your criteria.

Note that the Tesseract OCR software prefers black-on-white text, and while it will often work with white-on-black text, it will be more likely to fail in those cases.
