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.

Remarks

Please note, that not only all GdPictureOCR internal variables are reset to their default values, but also all internal variables of the Tesseract engine are reset to their default values as well.

Also be aware, that used OCR results in the current GdPictureOCR object are not released using this method.

Example

How to reset all internal variables.

VB.NET
C#

Using gdpictureOCR As GdPictureOCR = New GdPictureOCR()
    'Set some GdPictureOCR variables.
    gdpictureOCR.Context = OCRContext.OCRContextRawLine
    gdpictureOCR.CharacterSet = ",./<>?"
    gdpictureOCR.Timeout = 1000
 
    'Some some Tesseract variables.
    gdpictureOCR.SetVariable("chop_enable", "T")
    gdpictureOCR.SetVariable("use_new_state_cost", "F")
    gdpictureOCR.SetVariable("enable_new_segsearch", "0")
    gdpictureOCR.SetVariable("edges_max_children_per_outline", "40")
 
    'Reset all internal variables to their default values.
    gdpictureOCR.ResetParameters()
End Using

using (GdPictureOCR gdpictureOCR = new GdPictureOCR())
{
    //Set some GdPictureOCR variables.
    gdpictureOCR.Context = OCRContext.OCRContextRawLine;
    gdpictureOCR.CharacterSet = ",./<>?";
    gdpictureOCR.Timeout = 1000;
 
    //Set some Tesseract variables.
    gdpictureOCR.SetVariable("chop_enable", "T");
    gdpictureOCR.SetVariable("use_new_state_cost", "F");
    gdpictureOCR.SetVariable("enable_new_segsearch", "0");
    gdpictureOCR.SetVariable("textord_force_make_prop_words", "F");
    gdpictureOCR.SetVariable("edges_max_children_per_outline", "40");
 
    //Reset all internal variables to their default values.
    gdpictureOCR.ResetParameters();
}
