/**
+ * @brief Creates a new displacement effect
*
- * Class for two state displacement effect shader that works on a per object basis. By passing a height-normal map as an effect image, the user can create
+ * Two state displacement effect shader that works on a per object basis. By passing a height-normal map as an effect image, the user can create
* various styles of buttons on an image actor. The shader requires two height-normal maps in one image, one for each state.
*
* The normals and height information for the two states of the button should be strictly specified in this format:
* Usage example:-
*
* // Create shader used for doing soft button\n
- * DisplacementEffect buttonEffect = DisplacementEffect::New();
+ * ShaderEffect buttonEffect = CreateDisplacementEffect();
* buttonEffect.SetEffectImage(Image::New( FANCY_BUTTON_HEIGHT_MAP_IMAGE_PATH ););
*
* // set shader to the soft button\n
*
*
* Animation animation = Animation::New( ... );\n
- * animation.AnimateTo( Property(buttonEffect, buttonEffect.GetStatePropertyName()), 1.0f, AlphaFunction::BOUNCE, ... );\n
+ * animation.AnimateTo( Property(buttonEffect, "uState"), 1.0f, AlphaFunction::BOUNCE, ... );\n
* animation.Play();\n
*
+ * Animatable/Constrainable uniforms:
+ * "uLightDirection" - The light direction is used in the lighting calculation. The angle of incidence directly affects the amount of light reflected.
+ * Default (0.0f, 0.7070168f, 0.7071068f), i.e angled at the surface from in front and above.
+ * "uAmbientLightColor" - The ambient light is used in the lighting calculation. Care must be taken to not saturate the image by setting this value too high,
+ * or the indentation will not look correct. Default 0.15.
+ * "uDiffuseLightColor" - The diffuse light is used in the lighting calculation. Default is (1.0f, 1.0f, 1.0f).
+ * "uLightMultiplier" - The ambient and diffuse lighting is multiplied by this factor. Since a diffuse light at an angle will cause the whole image to darken,
+ * this property can be used to scale the image back up closer to the pixel values of the original diffuse texture. Care must be taken
+ * to not saturate the image,or the indentation will not look correct. Default 1.0
+ * "uState" - The shader can have a maximum of two end states 0 or 1, Animate between these two values to do the transitions
+ * between states. Default 0.0
+ * "uHightScale" - The height displacement is multiplied by this factor. Tweak this to get the required level of depth. Default 0.1
+ * "uFixedNormal" - The Fixed normal will be used for the light calculation. Tweak this to get the required level of light.
+ * Only applicable for the FIXED type shader and not for DISPLACED type
+ *
+ * @param type The type of the effect, can be either DISPLACED, or FIXED.
+ * @return A handle to a newly allocated ShaderEffect
+ *

/**
+ * @brief Create a new MotionBlurEffect
*
- * Class for motion blur shader that works on a per object basis. Objects will
+ * Motion blur shader works on a per object basis. Objects will
* blur when they move, or if the camera moves. Can be applied to ImageActor or
* TextActor only.
*
* Usage example:-
*
* // Create shader used for doing motion blur\n
- * MotionBlurEffect MotionBlurEffect = MotionBlurEffect::New();
+ * ShaderEffect MotionBlurEffect = CreateMotionBlurEffect();
*
* // set actor shader to the blur one\n
- * Actor Actor = Actor::New( ... );\n
- * Actor.SetShaderEffect( MotionBlurEffect );
+ * Actor actor = Actor::New( ... );\n
+ * actor.SetShaderEffect( MotionBlurEffect );
*
+ * // Constrain "uModelLastFrame" to be the same as the actor's world matrix\n
+ * Dali::Property::Index uModelProperty = MotionBlurEffect.GetPropertyIndex( "uModelLastFrame" );
+ * Constraint constraint = Constraint::New<Matrix>( MotionBlurEffect, uModelProperty, EqualToConstraint() );\n
+ * constraint.AddSource( Source( actor , Actor::Property::WORLD_MATRIX ) );\n
+ * constraint.Apply();\n
+ *
+ *
+ * Animatable/Constrainable uniforms:
+ * "uBlurTexCoordScale" - This scales the offset for texture samples along the motion velocity vector.
+ * A smaller value means the samples will be spaced closer, larger value further
+ * apart. User should use this to get the blur to look contiguous, i.e. the blur
+ * texels should not be too widely spread, with gaps in between. Default 0.125.
+ * "uGeometryStretchFactor" - This scales the amount the geometry stretches backwards along the motion velocity
+ * vector. A smaller value means the geometry stretches less, larger it stretches more.
+ * User should use this to get the blur to 'bleed' into areas outside the physical
+ * bounds of the actor. We need this as the blur is only applied inside the bounds of
+ * the actor, but you would expect motion blur trails where the actor was previously
+ * but is there no longer. Default 0.05.
+ * "uSpeedScalingFactor" - This takes the magnitude of the motion velocity vector and scales it to produce a
+ * value which is used to fade the blur in / out with the speed that the actor is moving.
+ * As the blur fades in, more of the blur is visible and less of the original actor, and
+ * viceversa. This value is also used to control how much to fade the actor near the
+ * edges, based on the speed the actor is moving. When the actor is at rest this is not applied.
+ * Default 0.5.
+ * "uObjectFadeStart" - The displacement from the centre of the actor that the actor will start to fade towards its
+ * edges. This is used to prevent an unsightly hard edge between the blurred actor and the scene.
+ * Depends on the values of the vertices in the vertex stream. When the actor is at rest this is
+ * not applied. Default 0.25, which is half way towards the edge for an ImageRenderer::QUAD.
+ * "uObjectFadeEnd" - The displacement from the centre of the actor that the actor will finish fading towards its
+ * edges. This is used to prevent an unsightly hard edge between the blurred actor and the scene.
+ * Depends on the values of the vertices in the vertex stream. When the actor is at rest this is
+ * not applied.Default 0.5, which is all the way towards the edge for an ImageRenderer::QUAD.
+ * "uAlphaScale" - Global scaler applied to the alpha of the actor. Used to make the blurred actor a bit more subtle
+ * (helps to hide discontinuities due to limited number of texture samples) and reveal a bit of the
+ * background behind it as it moves. When the actor is at rest this is not applied. Default 0.75.
+ * "uNumSamples" - The number of texture samples to be taken. Increasing the number of samples provides better quality
+ * at the cost of performance.
+ * "uModelLastFrame" - The model to world space transformation matrix of the actor in the previous frame.
+ *
+ * @param numBlurSamples Number of samples used by the shader
+ * @return A handle to a newly allocated ShaderEffect

+ * @brief Creates a new MotionStretchEffect
*
- * Class for motion stretch shader that works on a per object basis. Objects will stretch in the direction of motion when they move, or if the camera moves. Can be applied
+ * Motion stretch shader works on a per object basis. Objects will stretch in the direction of motion when they move, or if the camera moves. Can be applied
* to ImageActor or TextActor only.
*
* Usage example:-
*
* // Create shader used for doing motion stretch\n
- * MotionStretchEffect MotionStretchEffect = MotionStretchEffect::New();
+ * ShaderEffect MotionStretchEffect = CreateMotionStretchEffect();
*
* // set actor shader to the stretch one\n
- * Actor Actor = Actor::New( ... );\n
- * Actor.SetShaderEffect( MotionStretchEffect );
+ * Actor actor = Actor::New( ... );\n
+ * actor.SetShaderEffect( MotionStretchEffect );
*
+ * // Constrain "uModelLastFrame" to be the same as the actor's world matrix\n
+ * Dali::Property::Index uModelProperty = MotionBlurEffect.GetPropertyIndex( "uModelLastFrame" );
+ * Constraint constraint = Constraint::New<Matrix>( MotionBlurEffect, uModelProperty, EqualToConstraint() );\n
+ * constraint.AddSource( Source( actor , Actor::Property::WORLD_MATRIX ) );\n
+ * constraint.Apply();\n
+ *
+ * Animatable/Constrainable uniforms:
+ * "uGeometryStretchFactor" - This scales the amount the geometry stretches along the motion velocity vector.
+ * A smaller value means the geometry stretches less, larger it stretches more. Default 0.5.
+ * "uSpeedScalingFactor" - This value is used to control how much to fade the actor near the edges, based on the
+ * speed the actor is moving. When the actor is at rest this is not applied. Default 0.5.
+ * "uObjectFadeStart" - The displacement from the centre of the actor that the actor will start to fade towards
+ * its edges. This is used to prevent an unsightly hard edge between the stretched actor and
+ * the scene. Depends on the values of the vertices in the vertex stream. When the actor is at
+ * rest this is not applied. Default Vector2(0.25, 0.25), which is half way towards the edge for
+ * an ImageRenderer::QUAD.
+ * "uObjectFadeEnd" - The displacement from the centre of the actor that the actor will finish fading towards its edges.
+ * This is used to prevent an unsightly hard edge between the stretched actor and the scene. Depends
+ * on the values of the vertices in the vertex stream. When the actor is at rest this is not applied.
+ * Default 0.5, which is all the way towards the edge for an ImageRenderer::QUAD.
+ * "uAlphaScale" - Global scaler applied to the alpha of the actor. Used to make the stretched actor a bit more subtle
+ * and reveal a bit of the background behind it as it moves. When the actor is at rest this is not
+ * applied. Default 0.75.
+ * "uModelLastFrame" - The model to world space transformation matrix of the actor in the previous frame.
+ *

- * @brief PageTurnEffect is a custom shader effect to achieve page turn effect for Image actors.
- *
- * Usage example:-
- *
- * // create shader used for doing page-turn effect\n
- * PageTurnEffect pageTurnEffect = PageTurnEffect::New();
- *
- * // set image actor shader to the page-turn one\n
- * // for portrait view, one image actor for each page\n
- * // for landscape view, the page turned over is still visible, so back image is needed \n
- * // in this case, create another image Actor using the back image and added to the page actor \n
- * ImageActor pageActor = ImageActor::New(....); \n
- * ImageActor backImageActor = ImageActor::New(....); \n
- * pageActor.Add(backPageActor);\n
- * pageActor.SetShaderEffect ( pageTurnEffect ); \n
- *
- * //set initial values
- * pageTurnEffect.SetPageSize();\n
- * pageTurnEffect.SetOriginalCenter();\n
- * pageTurnEffect.SetIsTurningBack();\n
- * pageTurnEffect.SetCurrentCenter();\n
- *
- * //Animate it with the current center property\n
- * Animation animation[mAnimationIndex] = Animation::New( ... );\n
- * animation.AnimateTo(Property( pageTurnEffect, pageTurnEffect.PageTurnEffect::GetCurrentCenterPropertyName() ),
- * currentCenter,
- * AlphaFunction::...);\n
- * animation[mAnimationIndex].Play(); \n

/**
+ * @brief Creates a new soft button shader effect
*
- * Class for soft button shader that works on a per object basis. Using animatable parameters user can create effect of button pushing in / out. Can be applied to ImageActor only.
+ * Soft button shader effect works on a per object basis. Using animatable parameters user can create
+ * effect of button pushing in / out. Can be applied to ImageActor only.
*
* Usage example:-
*
* // Create shader used for doing soft button\n
- * SoftButtonEffect softButtonEffect = SoftButtonEffect::New();
+ * ShaderEffect softButtonEffect = CreateSoftButtonEffect();
*
* // set image actor shader to the soft button one\n
* ImageActor imageActor = ImageActor::New( ... );\n
*
* // animate a button push, using e.g. AlphaFunction::BOUNCE. With these values the button pushes in and pops out slightly at the end\n
* Animation animation = Animation::New( ... );\n
- * animation.AnimateTo( Property(softButtonEffect, softButtonEffect.GetLightingIndentationAmountPropertyName()), 0.25f, AlphaFunction::BOUNCE, ... );\n
- * animation.AnimateTo( Property(softButtonEffect, softButtonEffect.GetLightingIndentationAmountPropertyName()), -0.05f, AlphaFunction::BOUNCE, ... );\n
- * animation.AnimateTo( Property(softButtonEffect, softButtonEffect.GetTextureDistortionAmountPropertyName()), 0.25f, AlphaFunction::BOUNCE, ... );\n
- * animation.AnimateTo( Property(softButtonEffect, softButtonEffect.GetTextureDistortionAmountPropertyName()), -0.05f, AlphaFunction::BOUNCE, ... );\n
+ * animation.AnimateTo( Property(softButtonEffect, "uLightingIndentationAmount), 0.25f, AlphaFunction::BOUNCE, ... );\n
+ * animation.AnimateTo( Property(softButtonEffect, "uLightingIndentationAmount"), -0.05f, AlphaFunction::BOUNCE, ... );\n
+ * animation.AnimateTo( Property(softButtonEffect, "uTextureDistortAmount"), 0.25f, AlphaFunction::BOUNCE, ... );\n
+ * animation.AnimateTo( Property(softButtonEffect, "uTextureDistortAmount"), -0.05f, AlphaFunction::BOUNCE, ... );\n
* animation.Play();\n
*
+ * Animatable/Constrainable uniforms:
+ *
+ * "uLightingIndentationAmount" - This property changes the lighting, to make it look like the button is pushed in. User should animate
+ * this in conjunction with texture distortion. Allowable values range from [-1..1], higher values give
+ * more change in lighting. Default 0.0 (no lighting change).
+ * "uTextureDistortAmount" - This property changes the distortion, to make it look like the button is pushed in. User should animate
+ * this in conjunction with lighting indentation. Allowable values range from [-1..1) - note 1.0 is NOT
+ * allowed - higher values give more distortion. Default 0.0 (no distortion).
+ * "uAmbientLight" - The ambient light is used in the lighting calculation. Care must be taken to not saturate the image by
+ * setting this value too high, or the indentation will not look correct. Default 0.15
+ * "uDiffuseLight" - The diffuse light is used in the lighting calculation. Default is (0.0, 0.7070168, 0.7070168),
+ * i.e. a light angled at the surface from in front and above. Note that you need to Normalize()
+ * the Vector3 that you set with this property
+ * "uLightMultiplier" - The ambient and diffuse lighting is multiplied by this factor. Since a diffuse light at an angle will
+ * cause the whole image to darken, even outside the soft button indentation, this property can be used
+ * to scale the image back up closer to the pixel values of the original diffuse texture. Care must be
+ * taken to not saturate the image,or the indentation will not look correct. Default 1.2.
+ * "uInsideCircleSizeScale" - The SoftButtonEffect consists of two shapes, one inside the other. The outside shape fits exactly to
+ * the actor, touching its edges but completely contained. The inside shape size is given by a multiplier
+ * of the outside shape size. For example a value of 0.5 means that the inside shape is half the size of
+ * the outside one. Allowable values are in the range (0.0 - 1.0), note that 0.0 and 1.0 themselves are
+ * not allowed. Default 0.75.
+ * "uOutsideCircleDepth" - The SoftButtonEffect consists of two shapes, one inside the other. The depth of the indentation at the
+ * transition between the inside and outside shapes is controlled by this property. The values lies in the
+ * range [0.0 - 1.0]. A value of 0.0 means the outside shape has no depth (and is thus invisible), value of
+ * 1.0 means the outside shape has maximum depth (and the inside shape is thus invisible). Default 0.05
+ * "uEffectRegion" - The soft button effect is applied within the supplied rect region of the texture. Default values for this
+ * is (0.0, 0.0, 1.0, 1.0) which is the entire image with 0,0 being the top left and 1.0, 1.0 being the bottom
+ * right. If the image texture is split between multiple ImageActors then the developer should specify the pixel
+ * area of the texture the effect should be applied with. Example, If the Image is split among two ImageActors
+ * side by side, with the left one using left half of the texture and right one using the right half of the
+ * texture then the pixel area value for the left ImageActor will be (0.0, 0.0, 0.5, 1.0) and the pixel area for
+ * the right will be (0.5,0.0,1.0,1.0).
+ * "uRectangleSizeScale" - This property can be used to set the mix between proportion of rectangle and proportion of ellipse - the
+ * result is a rectangle with rounded corners. If the value is 0.0, the shape is an ellipse. If the value is
+ * close to 1.0, the shape is close to a rectangle. The value lies in the range [0.0 - 1.0). Note that a value
+ * of 1.0 is NOT allowed.Default 0.5.
+ *
+ * @param type The type of the soft button, can be either ELLIPTICAL, RECTANGULAR, or FIXED.
+ * @return A handle to a newly allocated ShaderEffect

+ * "uSpineShadowParameter" - The two parameters are the major&minor radius (in pixels) to form an ellipse shape. The top-left

+ * "uIsBackImageVisible" - Set whether the current page is with its backside visible. Need to pass the parameter as true for

+ * View provides a container where different Dali::Layer instances and a background could be added. It

+ * This method rotates all layers accordingly with the given orientation, it emits an OrientationAnimationStartsSignal signal just before the rotation animation starts.
+ *
+ * By default view anchor point and parent origin are centered, the size is full screen and is got directly from the Dali::Stage. However, by passing \e false to the
+ * Toolkit::View::New() method a custom size could be specified, and after initialization, anchor point and parent origin could be updated.
+ *
+ * If a background is set, a background layer will be created and dropped to the bottom.
+ *
+ * Use example (application is a Dali::Application object):
+ * \code{.cpp}
+ * Stage stage = Stage::GetCurrent();
+ *
+ * // Create default View. By default it gets the stage size.

+ *
+ * // Add the view to the stage before setting the background.
