SetVerifyParameters

Sets the verification parameters in the supplied context.

Prerequisites The Fingerprint SDK library must have been previously initialized.

Return On success, GR_OK is returned.
If any supplied parameter is invalid or out of range, its default value will be used and GR_DEFAULT_USED is returned.
On failure, the appropriate error code is returned.

Parameters

[in] verifyThreshold

The verification score threshold.

[in] verifyRotationTolerance

The rotation tolerance for the verification process.

[in] context

Context in which the verification parameters will be set.

Sample Code

C++ .NET

// set the new verification parameters
ret = axGrFingerXCtrl2->SetVerifyParameters(thresholdVr, rotationMaxVr, GR_DEFAULT_CONTEXT);
// error?
if (ret == GR_DEFAULT_USED) {
  MessageBox::Show("Invalid verify parameters values. Default values will be used.");
}

C#

// set the new verification parameters
ret = axGrFingerXCtrl1.SetVerifyParameters(thresholdVr, rotationMaxVr, (int)GRConstants.GR_DEFAULT_CONTEXT);
// error?
if ((GRConstants)ret == GRConstants.GR_DEFAULT_USED) 
{
	MessageBox.Show("Invalid verify parameters values. Default values will be used.");
}

VB6

' set the new verification parameters
ret = GrFingerXCtrl1.SetVerifyParameters(thresholdVr, rotationMaxVr, GR_DEFAULT_CONTEXT)
' error?
If ret = GR_DEFAULT_USED Then
    MsgBox ("Invalid verify parameters values. Default values will be used.")
End If

VB .NET

' set the new verification parameters
ret = AxGrFingerXCtrl1.SetVerifyParameters(thresholdVr, rotationMaxVr, GRConstants.GR_DEFAULT_CONTEXT)
' error?
If ret = GRConstants.GR_DEFAULT_USED Then
    MsgBox("Invalid verify parameters values. Default values will be used.")
End If

Delphi

// set the new verification parameters
ret := GrFingerXCtrl1.SetVerifyParameters(thresholdVr, rotationMaxVr, GR_DEFAULT_CONTEXT);
// error?
if ret = GR_DEFAULT_USED then begin
    showmessage('Invalid verify parameters values. Default values will be used.');
end;
