SetVariable Method (GdPictureOCR)

In This Topic
Sets up a specified value for an internal parameter of the OCR engine. The Tesseract engine has a large number of control parameters to modify its behavior.Tesseract-OCR parameters

Syntax
'Declaration

 


Public Function SetVariable( _

   ByVal Name As String, _

   ByVal Value As String _

) As GdPictureStatus
public GdPictureStatus SetVariable(

public: GdPictureStatus SetVariable( 

   string* Name,

   string* Value

) 
public:

GdPictureStatus SetVariable( 

   String^ Name,

   String^ Value

)

Parameters

Name
The name of the parameter. You can find a wide range of possible variables listed in Tesseract-OCR parameters.
Value
The value for the specified parameter.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK

We strongly recommend always checking this status first.
