22.1 Class Library Name
The class library is:
Attrasoft.TransApplet70.LiveVideoInput70,
The class in this library will be:
Attrasoft.TransApplet70.LiveVideoInput70.LiveVideoInput70.
The interface, which will be used by VideoInput70, is:
public interface I_LiveVideoInput70
{
//1. parameters
bool getCaptureStatus();
bool getVideoToImagesDirStatus();
void setVideoToImagesDirStatus( bool b );
string getVideoToImagesDir();
void setVideoToImagesDir( string s);
// 2. action
bool initialization ();
bool attach ();
bool detach ();
string getMessage();
string getInfomation();
string toString();
}
The class, “LiveVideoInput70”, will have a constructor that will take a Picture Box and Panel:
public LiveVideoInput70( PictureBox pictureBox1a, Panel panel1a)
{
pictureBox1 = pictureBox1a;
panel1 = panel1a;
}
The Live Video will be displayed in the Panel and the Picture Box. You can obtain a live image at anytime via the Picture Box.
To declare an object, write:
internal Attrasoft.TransApplet70.LiveVideoInput70.LiveVideoInput70 lv70;
To create an object, write:
lv70 = new
Attrasoft.TransApplet70.LiveVideoInput70.LiveVideoInput70 (pictureBox2, panel1) ;
Make sure the Picture Box and Panel objects are created first. The first thing you will do is to initialize the LiveVideoInput70 object:
lv70.initialization ();
This will bring the live video to the Panel. To get images, we will need to bring the live image to the Picture Box. The following two commands will display and stop displaying live images to the Picture Box:
bool attach ();
bool detach ();
To make the Picture Box show live images, use the attach function. To stop the Picture Box from showing live images, use the detach function.
