About Surveillance / SubjectAppered and ImageCaptured

I have a trouble of getting face image of subject given by OnSubjectAppeared and also image of camera given by OnImageCaptured. I just want to these as bitmap so that i can use it.

When I look at simple code of sentiveillance, i can get what i want from :
Code: Select all
Surveillance.ImageCaptured += ForwardSurveillanceEvent;
Surveillance.SubjectAppeared += ForwardSurveillanceEvent;
Surveillance.SubjectTrack += ForwardSurveillanceEvent;
Surveillance.SubjectDisappeared += ForwardSurveillanceEvent;

However in SubjectAppeared, there is a property named as image but it gets all the time null.

Code: Select all
private void OnSubjectAppeared(SurveillanceEventData e)
            //There is e.Image, but null

About this issue, if you can help me I"ll be very pleased.

Thanks in advance.

What I"m working on is => SentiVeillance_5_0_SDK_TrialSamplesSurveillanceCSSimpleSurveillanceSampleCS

You can get bitmap image this way:
Code: Select all
e.Image.ToBitmap(); // Image is NImage type

In SimpleSurveillanceSampleCS, in CountSubjects.cs form, in "private void ForwardSurveillanceEvent(object sender, NSurveillanceEventArgs e)" method, when case is "NSurveillanceEventType.SubjectAppeared" you can get image this way:
Code: Select all
