Detailed Description

Capture snapshots the current scene and save as a file.

Since:
4.0, DALi version 1.3.4

Applications should follow the example below to create capture :

 Capture capture = Capture::New();

If required, you can also connect class member function to a signal :

 capture.FinishedSignal().Connect(this, &CaptureSceneExample::OnCaptureFinished);

At the connected class member function, you can know whether capture finish state.

 void CaptureSceneExample::OnCaptureFinished( Capture capture, Capture::FinishState state )
 {
   if ( state == Capture::FinishState::SUCCEEDED )
   {
     // Do something
   }
   else
   {
     // Do something
   }
 }

Member Typedef Documentation

typedef Signal< void ( Capture, Capture::FinishState ) > Dali::Capture::CaptureFinishedSignalType

Typedef for finished signals sent by this class.

Since:
4.0, DALi version 1.3.4

Member Enumeration Documentation

enum Dali::Capture::FinishState

The enumerations used for checking capture success.

Since:
4.0, DALi version 1.3.4
Enumerator:
SUCCEEDED 

Succeeded in saving the result after capture.

FAILED 

Failed to capture by time out or to save the result.

Constructor & Destructor Documentation

Dali::Capture::Capture ( )

Create an uninitialized Capture; this can be initialized with Actor::New().

Since:
4.0, DALi version 1.3.4

Calling member functions with an uninitialized Dali::Object is not allowed.

Dali::Capture::~Capture ( )

Dali::Actor is intended as a base class.

Since:
4.0, DALi version 1.3.4

This is non-virtual since derived Handle types must not contain data or virtual methods.

Dali::Capture::Capture ( const Capture &  copy)

This copy constructor is required for (smart) pointer semantics.

Since:
4.0, DALi version 1.3.4
Parameters:
[in]copyA reference to the copied handle.

Member Function Documentation

static Capture Dali::Capture::DownCast ( BaseHandle  handle) [static]

Downcast an Object handle to Capture handle.

Since:
4.0, DALi version 1.3.4

If handle points to a Capture object the downcast produces valid handle. If not the returned handle is left uninitialized.

Parameters:
[in]handleto An object.
Returns:
handle to a Capture object or an uninitialized handle.
CaptureFinishedSignalType& Dali::Capture::FinishedSignal ( )

Get finished signal.

Since:
4.0, DALi version 1.3.4
Returns:
finished signal instance.
static Capture Dali::Capture::New ( ) [static]

Create an initialized Capture.

Since:
4.0, DALi version 1.3.4
Returns:
A handle to a newly allocated Dali resource.
Note:
Projection mode of default cameraActor is Dali::Camera::PERSPECTIVE_PROJECTION
static Capture Dali::Capture::New ( Dali::CameraActor  cameraActor) [static]

Create an initialized Capture.

Since:
4.0, DALi version 1.3.4
Parameters:
[in]cameraActorAn initialized CameraActor.
Returns:
A handle to a newly allocated Dali resource.
Capture& Dali::Capture::operator= ( const Capture &  rhs)

This assignment operator is required for (smart) pointer semantics.

Since:
4.0, DALi version 1.3.4
Parameters:
[in]rhsA reference to the copied handle.
Returns:
A reference to this.
void Dali::Capture::Start ( Actor  source,
const Vector2 &  size,
const std::string &  path,
const Vector4 &  clearColor 
)

Start capture and save the image as a file.

Since:
4.0, DALi version 1.3.4
Parameters:
[in]sourcesource actor to be used for capture.
[in]sizecaptured size.
[in]pathimage file path to be saved as a file.
[in]clearColorbackground color of captured scene
void Dali::Capture::Start ( Actor  source,
const Vector2 &  size,
const std::string &  path 
)

Start capture and save the image as a file.

Since:
4.0, DALi version 1.3.4
Parameters:
[in]sourcesource actor to be used for capture.
[in]sizecaptured size.
[in]pathimage file path to be saved as a file.
Note:
Clear color is transparent.
