Detailed Description

Use ShadowEffect2D to apply drop- and inner-shadow post-processing effects to 2D nodes.

Examples

To create a shadow effect:

    // An effect that is assigned to a 2D node is an effect prefab.
    // Before you can construct an effect prefab, you must create an effect template.
    // This example creates an effect template for the ShadowEffect2D effect prefab.
    NodeEffectTemplate2DSharedPtr shadowEffectTemplate =
        NodeEffectTemplate2D::create(ShadowEffect2D::getStaticMetaclass()->getName(), "DropShadow");
 
    // Create a node effect prefab from the effect template.
    NodeEffectPrefab2DSharedPtr shadowEffectPrefab =
        NodeEffectPrefab2D::create(getDomain(), "DropShadow prefab", shadowEffectTemplate);

To set the shadow effect properties:

    // Create an effect template.
    NodeEffectTemplate2DSharedPtr shadowEffectTemplate =
        NodeEffectTemplate2D::create(ShadowEffect2D::getStaticMetaclass()->getName(), "DropShadow");
 
    // Set the value of the AngleProperty in the template. This value serves as the default value
    // of the property in instances of the effect prefab.
    shadowEffectTemplate->addPropertyValue(ShadowEffect2D::AngleProperty, Variant(35.f));
 
    // Create an effect prefab.
    NodeEffectPrefab2DSharedPtr shadowEffectPrefab =
        NodeEffectPrefab2D::create(getDomain(), "DropShadow prefab", shadowEffectTemplate);
 
    // Assign the effect to a 2D node.
    node2d->setEffectPrefab(shadowEffectPrefab);
 
    // Get the node-specific effect instance created from the assigned prefab.
    ShadowEffect2DSharedPtr shadowEffect = dynamic_pointer_cast<ShadowEffect2D>(node2d->getEffect());
 
    // Set the shadow distance to 15 pixels for this node only. This overrides
    // the property default value defined by the ShadowEffect2D metaclass.
    shadowEffect->setDistance(15.f);
 
    // Set the direction of the shadow to 55 degrees relative to the positive x axis.
    // This overrides the default value of 35 degrees set in the shadow effect template.
    shadowEffect->setAngle(55.f);

◆ BlendModeProperty

PropertyType<int> kanzi::ShadowEffect2D::BlendModeProperty

static

Sets the blend mode to use for rendering the shadow.

See also: setBlendMode(), getBlendMode()

Since: Kanzi 3.9.8

◆ BlurRadiusProperty

PropertyType<float> kanzi::ShadowEffect2D::BlurRadiusProperty

static

Sets the softness of the shadow by defining the distance in pixels the shadow blur extends outward from an edge.

For a shadow with sharp edges, set to 0. The default value is 8.

See also: setBlurRadius(), getBlurRadius()

◆ QualityProperty

PropertyType<Quality> kanzi::ShadowEffect2D::QualityProperty

static

Sets the visual quality of the shadow.

Lower quality uses less computing and memory resources. The default value is Normal.

See also: setQuality(), getQuality()

◆ TypeProperty

PropertyType<Type> kanzi::ShadowEffect2D::TypeProperty

static

Sets the type of the shadow:

DropShadow appears behind or below an object. This is the default value.
InnerShadow appears inside an object.

setType(), getType()

◆ DistanceProperty

PropertyType<float> kanzi::ShadowEffect2D::DistanceProperty

static

Sets how far to move the shadow from the object in the direction set by the AngleProperty.

The default value is 10.

See also: setDistance(), getDistance()

◆ AngleProperty

PropertyType<float> kanzi::ShadowEffect2D::AngleProperty

static

Sets the direction of the shadow as an angle relative to the positive x-axis.

The default value is 45.

See also: setAngle(), getAngle()

◆ OverrideOffsetProperty

PropertyType<Vector2> kanzi::ShadowEffect2D::OverrideOffsetProperty

static

Sets the offset of the shadow from the object along the x and y axes in pixels.

When you set this property, the AngleProperty and DistanceProperty have no effect. To disable the offset override, remove this property.

See also: setOverrideOffset(), getOverrideOffset()

Since: Kanzi 3.9.6

◆ ActualOffsetProperty

PropertyType<Vector2> kanzi::ShadowEffect2D::ActualOffsetProperty

static

Gets the calculated offset of the shadow from the object along the x and y axes in pixels.

Kanzi calculates the offset from the values of the DistanceProperty and AngleProperty or, if the OverrideOffsetProperty is set, from its value.

See also: setActualOffset(), getActualOffset()

Since: Kanzi 3.9.6

◆ ColorProperty

PropertyType<ColorRGBA> kanzi::ShadowEffect2D::ColorProperty

static

Sets the color of the shadow.

The default value is ColorRGBA(0.f, 0.f, 0.f, 0.75f).

See also: setColor(), getColor()

◆ ShadowOnlyProperty

PropertyType<bool> kanzi::ShadowEffect2D::ShadowOnlyProperty

static

Sets whether to render only the shadow without the node contents.

The default value is false.

See also: setShadowOnly(), getShadowOnly()

◆ m_premultipliedColor

ColorRGBA kanzi::ShadowEffect2D::m_premultipliedColor

protected

Premultiplied color for the shadow.

◆ m_defaultStackingMode

ClassPropertyDefaultValue<EffectStack2D::StackingMode> kanzi::ShadowEffect2D::m_defaultStackingMode

protected

Default value for EffectStack2D::StackingModeProperty.
