Overview of the Camera control

Window control

The Camera control is used to:
  • WinDev view the video sequence currently broadcasted by a camera connected to the current computer.
You have the ability to save this video sequence or a photo of this video sequence.

Creating a Camera control

To create a Camera control:
  1. In the window editor, click(or select "Insert .. Control .. Camera control").On the "创建" pane, in the "显示控件" group:
    • WinDev expand "Video and Capture" and select "Camera".
  2. Click the position where the control must be created in the window. The control appears in creation mode.
To display the characteristics of the control, select "Description" from the popup menu of the control.

The Camera control can be handled by programming via the Video functions.
