Description

The OCROptions.RecognitionRejection property lets you specify the threshold used to decide if the recognition of a character fails or not. To learn more about the character recognition threshold, see Optical Character Recognition. The value set in this property takes effect only if the OCROptions.RecognitionRejectionAuto property is False.

Declaration

OCROptionsObj.RecognitionRejection

Read-Write Property Real
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 from 0.0 to 1.0 that denotes the character recognition threshold.

Example

The following example sets the custom character recognition threshold value to 0.5 and recognizes characters written in Windows Notepad by using the specified recognition threshold. After that, it posts the recognized characters to the test log.
