Overview

Control of a WINDEV Mobile window

The Camera control is used to:
You can save this video or save a video snapshot.
Remark: You can use the native camera of the device to record a video or take a photo (CameraRunApp).
New in version 28
Mac Catalyst This control is now available in Catalyst mode.

Creating a Camera control

To create a Camera control:
  1. On the "Creation" tab, in the "Graphic controls" group, click "Camera".
  2. Click at the desired location to create the control. The control appears in the editor.
To view the characteristics of the control, select "Description" in the context menu.
The Camera control can be handled programmatically using the Camera functions.
Remark: These functions are also available with a prefix syntax. For more details, see Camera functions (Prefix syntax).
Remarks:
  • A single Camera control can be used in a window.
  • The Camera control exists in 2 versions:
    • Mode 27 or higher: Camera control created in version 27. It allows using all the new functions and properties available from version 27 onwards (see below).
    • Version-26-compatible mode: Camera control created before version 26. It uses features deprecated by Google. The "Version-26-compatible" mode, available in the control description window, is used to keep the same behavior as in previous versions. If this option is unchecked, the control will be set to mode 27 or higher.

Smart control

WINDEV Mobile features a Smart control to use the camera of the device. All the main functionalities are integrated in this Smart control. It has a Button control (to be added in the window that will open the camera of the device) and a window (opened by the Button control).
To add the Smart control in your window:
  1. In the editor, open the window in which the camera button will be integrated.
  2. On the "Creation" tab, in the "Graphic controls" group, expand "Camera".
  3. Click the control that appears and then click in the window to set the position of the button. The button is created and the "WIN_Mobile_Camera_UI" window is added to the project. This window contains different planes that allow you to manage photo capture and video recording.

Managing thumbnails

If photos must be used in Android applications, we advise you to work with thumbnails and not with the initial photos taken by the device. These thumbnails can be generated by CameraGenerateThumbnail.
This example presents how to take photos and generate thumbnails.
sImageFile is string
sThumbnail is string
 
// Takes a photo with the camera of the Android device
sImageFile = CameraRunApp(viVideoCapture)
IF sImageFile = "" THEN
Error("Unable to take the photo.", ErrorInfo())
RETURN
END
 
// Generates a thumbnail from the photo taken by the device
// and displays the thumbnail in an Image control
sThumbnail = fExtractPath(sImageFile, fDrive + fDirectory + fFile) + "_thumb.jpg"
IF CameraGenerateThumbnail(sImageFile, sThumbnail) = True THEN
IMG_Photo = sThumbnail
ELSE
Error("Unable to generate the thumbnail.", ErrorInfo())
END
