CameraRunApp (Function)

In french: CaméraLanceAppli

Starts the device's native camera application to record a video or to take a photo.

Remarks:

Note: Syntax 2 using a non-blocking call is recommended, especially from iOS 8 onwards.
In a WINDEV application, CameraCapture can be used to record a video or to take a photo with the camera of the device.
This function is equivalent to VideoStartApp.

Example

sPhoto is string
sPhoto = CameraRunApp(viPictureCapture)
IF sPhoto <> "" THEN
	Info("Photo sauvegardée dans le fichier " + sPhoto)
END

nTypeEnregistrement is int
// Laisse l'utilisateur décider du type de capture
IF Dialog("Souhaitez-vous enregistrer une image ou une vidéo ?", ["Une image", ...
	"Une vidéo"], 1, 2, dlgIconQuestion) = 1 THEN
	nTypeEnregistrement = viPictureCapture
ELSE
	nTypeEnregistrement = viVideoCapture
END
// Lance l'application
CameraRunApp(nTypeEnregistrement, CaméraLanceAppli_Callback)

INTERNAL PROCEDURE CaméraLanceAppli_Callback(sChemin is string)
	// Si le retour vaut chaîne vide (""), une erreur a eu lieu
	IF sChemin ~= "" THEN
		Error(ErrorInfo())
		RETURN
	END
	// Message de fin d'enregistrement
	Info("Le fichier a été enregistré ici : " + sChemin)
END

Remarks

Photos and videos saved

The photo and video settings (format, resolution, size) are the ones defined in the native camera application.

To display the photo in an Image control, open the Image control description, go to the "Details" tab and check "Orientate according to the image's Exif data".

Backup directories

In Android applications, the photo or video is stored on the SD Card of the device and is automatically added to the album.
If photos must be used in your Android applications, we advise you to work with thumbnails and not with the initial photos taken by the device. To generate the thumbnails, use CameraGenerateThumbnail.

In iPhone/iPad applications:
By default:

the photos are saved in the "Documents" directory of application.
the videos are saved in the "tmp" directory of application.

For the images, you can also:

store the binary content of the image in a database, via a Memo item.
add the photo to the photo album of the device with AlbumSave. In this case, the image can be re-used via AlbumPicker.
