VideoBox Control
Description
The VideoBox control allows you to display video for the Vision Guide option in your forms.
Usage
You can easily display a video window on a form in your application by using the VideoBox control. When you run a vision sequence, the graphics can also be displayed on the window.
Perform the following steps to create a vision window:
- Place a VideoBox control on the form you want the video to be displayed.
The control size can be changed up to the full size. - Set the VideoEnabled property to True.
- Set the GraphicsEnabled property to True if you want to display vision graphics.
- By default, the Camera property value is 0.
This allows the videobox to display video from any camera when a sequence is run. Set the Camera property to any camera number in the project to show the video and sequence graphics for that camera.
The video is automatically scaled to fit the size of the VideoBox. When you change the height or width of the videobox, the aspect ratio is maintained.
Setting VideoBox Appearance
Use the BorderStyle property to change the appearance of the videobox.
