OCROptions Object

Applies to TestComplete 14.30, last modified on November 21, 2019
This object 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 object is used to configure settings that affect how optical character recognition in the visible area of the onscreen object will be performed. To get the OCROptions object, call the OCRObject.CreateOptions method.

Example

The following code snippet creates an OCROptions object that contains the default character recognition settings and then posts those default settings to the test log.
