SearchAccuracy Property

Applies to TestComplete 15.40, last modified on July 05, 2022
This property is provided by the legacy OCR plugin. In version 12.60, the plugin was replaced with the new Optical Character Recognition plugin powered by Google Cloud Vision API. To learn more, see Optical Character Recognition.
The legacy OCR plugin was removed from TestComplete in version 12.60. If you need to use objects, methods, and properties provided by the legacy plugin with this version of TestComplete, please contact our Customer Care team. The legacy OCR plugin was restored in TestComplete version 14.0. To use the objects, methods, and properties with this or later TestComplete version, you need to install and enable the plugin manually.

Description

The OCROptions.SearchAccuracy property defines a numerical representation of how much the recognized string should match the string passed to the OCRObject.FindRectByText method in order to consider them as identical. This property is used only when the OCROptions.ExactSearch property is set to False.

To learn more about character recognition in TestComplete, see Using Optical Character Recognition.

Declaration

OCROptionsObj.SearchAccuracy

Read-Write Property Double
OCROptionsObj An expression, variable or parameter that specifies a reference to an OCROptions object

Applies To

The property is applied to the following object:

OCROptions

Property Value

A real value ranging from 0 to 1 that denotes the accuracy of string comparison. If SearchAccuracy is set to 1, the exact string matches will be sought. The default value of this property is 0.6.

Example

The following example uses the OCROptions object to specify that the OCRobject.FindRectByText method will not use the exact search and sets the search accuracy to 0.3. After that, it searches for the "Test" string within the text written in Windows Notepad by using the specified OCR options. The rectangle containing the found text is posted to the test log.
