OCRConfigurations {
    myOcrCommand1 {
        commandLineParametersFormat = <String>
        executableSuffix = <String>
        timeoutSeconds = <Number>
    }
    ...
}

Parameters

  • commandLineParametersFormat - The format of the Command Line

    • Detailed information can be found here

  • executableSuffix - Can be configured if the Tesseract Command needs to have a suffix like .exe

    • This is usually needed on Windows operating systems

  • timeoutSeconds - This is the maximum amount of time that the command should wait

    • If this timeout is reached, the Tesseract Command will be canceled and the test case will fail

OCRConfigurations {
    myOcrCommand1 {
        commandLineParametersFormat = "param1 %s param2 %s"
        executableSuffix = ".exe"
        timeoutSeconds = 90
    }
}

When OCR Built-ins are configured, the following OCR command can be executed.

Syntax

1
 Ocr.ocr(<configurationKey String>, [<dynamicParameters String, ...>])

Parameters

  • configurationKey -The name of the configuration used in OCRConfigurations

  • dynamicParameters - The parameters that will be appended to the tesseract command according to the commandLineParametersFormat configuration

Example 

1
Ocr.ocr("myOcrCommand1", ["param1Value", "param2Value"])

This will result in the following execution with a timeout of 90 seconds: 

1
tesseract.exe param1 param1Value param2 param2Value
