CameraConfigure (Function)

In french: CameraConfigure

Allows you to configure the video capture driver. This configuration can be set by the user (via a dialog box) or programmatically (resolution configuration).

Warning: This function can only be used with Camera fields in compatible mode (option "Use the former 'Video for Windows' APIs (compatibility)" checked in the field description)..

Note: This function is equivalent to VideoConfigure.

Example

// Affiche la boîte de dialogue standard permettant la configuration du driver de capture vidéo 
// utilisé pour le champ "CAM_MaVidéo"
CameraConfigure(CAM_MaVidéo)

// Spécifie une résolution de 640 par 480
CameraConfigure(CAM_VIDEO1, viResolution, 640, 480)

Syntax

<Result> = CameraConfigure(<Camera control> [, <Type of configuration> [, <Resolution in width> , <Resolution in height>]])

<Result>: Boolean

True if the standard dialog box is displayed,
False if an error occurs. The corresponding error message is returned by ErrorInfo.

<Camera control>: Control name

Name of the Camera control to be used.

<Type of configuration>: Optional integer constant

Type of configuration to perform:
viConfigureFormat Display a dialog box (if it exists) allowing the user to specify the camera resolution, the number of colors used, etc.
viConfigureSource
(default value) Display a dialog box (if it exists) allowing the user to specify the name of camera to use and the parameters of this camera (saturation for example).
This dialog box depends on the driver used by the Camera control.
viResolution Used to specify a resolution for the camera, via <Resolution in width> and <Resolution in height>.

<Resolution in width>: Optional integer

Width of camera resolution (in pixels). This parameter must be specified if <Type of configuration> is set to viResolution.

<Resolution in height>: Optional integer

Height of the camera resolution (in pixels). This parameter must be specified if <Type of configuration> is set to viResolution.

Remarks

Operating mode of the Camera control when displaying dialog boxes

If the panel for configuring the format is displayed, the Camera control is frozen.
If the configuration panel is displayed by the viConfigureSource constant, the Camera control continues to operate. The modifications of the parameters are immediately taken into account and applied to the Camera control in "direct live".
