ExtendedCamera Class

Namespace: id3.Devices

Definition

Enhances Camera with functionalities for detailed stream management, supporting operations to query available streams, control stream states, and access live framesets.

Python

class ExtendedCamera

Dart

class ExtendedCamera implements Finalizable

C#

public partial class ExtendedCamera

Java

public class ExtendedCamera implements AutoCloseable, Serializable

C

typedef struct id3DevicesExtendedCamera *ID3_DEVICES_EXTENDED_CAMERA;

Usage

Python

extendedCameraInstance = ExtendedCamera()
# ...

Explicit destruction

# ...
del extendedCameraInstance

Dart

final extendedCameraInstance = sdk.ExtendedCamera();
// ...

Explicit destruction

// ...
extendedCameraInstance.dispose()

C#

using (var extendedCameraInstance = new ExtendedCamera())
{
   // ...
}

Explicit destruction

var extendedCameraInstance = new ExtendedCamera()
// ...
extendedCameraInstance.Dispose()

Java

try (ExtendedCamera extendedCameraInstance = new ExtendedCamera()) {
// ...
}

Explicit destruction

ExtendedCamera extendedCameraInstance = new ExtendedCamera();
// ...
extendedCameraInstance.close();

C

ID3_DEVICES_EXTENDED_CAMERA hExtendedCamera{};
int err = id3DevicesExtendedCamera_Initialize(&hExtendedCamera);
if (err == ID3_SUCCESS) {
    // ...
    id3DevicesExtendedCamera_Dispose(&hExtendedCamera);
}

Methods

Name	Description
addDeviceFilter	Adds a filter to specify the types of devices this channel should handle.
applyParameters	Applies a set of parameters to the device.
checkCommand	(C++/dotnet): Checks if a specific command is available on the device.
checkParameter	Confirms if a parameter exists on the device.
clearDeviceFilter	Clears all set device filters, removing any type restrictions.
closeDevice	Controls closing the associated device.
enableStream	(C++/dotnet): Toggles the activation state of a specified stream.
getCurrentFrame	Fetches the most recent frame from the live feed.
getCurrentFrameset	Fetches the most recent set of frames captured across enabled streams.
getLastSnapshot	Fetches the most recent snapshot taken by the takeSnapshot function.
getMeasurementData	Retrieves a list of measurement data collected during capture sessions.
getParameter	Retrieves a device parameter’s value.
getParameterDescriptor	Fetches the descriptor of a device parameter.
getParameterList	Obtains all supported parameters, optionally filtered by category.
getParameterNameList	Retrieves names of all supported parameters, optionally filtered by category.
getParameterValueInt	Gets the integer value of a device parameter.
getSpecificFrame	Gets a specific live frame.
getStreamStatus	Queries the current status (enabled/disabled) of a specific stream.
getSupportedStreams	Retrieves a list of all streams supported by the device.
isPreviouslyDisconnectedDevice	Checks if the specified device was previously disconnected.
openDevice	Controls opening the associated device.
sendCommand	(C++/dotnet): Issues a command to the device.
sendCommandBoolean	(C++/dotnet): Issues a command with a boolean as result to the device.
sendModelCommand	(C++/dotnet): Dispatches a command to the device model.
setParameter	Sets a device parameter’s value.
setParameterValueInt	Assigns an integer value to a device parameter.
startCapture	Initiates data capture, allowing for an optional parameter to specify capture modes or configurations.
stopCapture	Ends the data capture process, stopping the live feed or any ongoing capture activity.
takeSnapshot	Triggers a snapshot capture process, with the result accessible through getLastSnapshot.
waitForCapture	Waits for new capture data within a specified timeout period.
