Detailed Description

Use BlurEffect2D to apply a Gaussian blur post-processing effect to 2D nodes.

Examples

To create a blur effect:

    // Create an effect template for the BlurEffect2D effect prefab.
    NodeEffectTemplate2DSharedPtr blurEffectTemplate =
        NodeEffectTemplate2D::create(BlurEffect2D::getStaticMetaclass()->getName(), "BlurEffect");
    // Create a node effect prefab from the effect template.
    NodeEffectPrefab2DSharedPtr blurEffectPrefab =
        NodeEffectPrefab2D::create(getDomain(), "BlurEffect prefab", blurEffectTemplate);

To set the blur effect properties:

    // Create a blur effect template.
    NodeEffectTemplate2DSharedPtr blurEffectTemplate =
        NodeEffectTemplate2D::create(BlurEffect2D::getStaticMetaclass()->getName(), "BlurEffect");
    // Set the value of the RadiusProperty in the blur effect template.
    // RadiusProperty defines the amount of blur.
    blurEffectTemplate->addPropertyValue(BlurEffect2D::RadiusProperty, Variant(6.f));
    // Create a blur effect prefab.
    NodeEffectPrefab2DSharedPtr blurEffectPrefab =
        NodeEffectPrefab2D::create(getDomain(), "BlurEffect prefab", blurEffectTemplate);
    // Assign the blur effect to a 2D node.
    node2d->setEffectPrefab(blurEffectPrefab);
    // Get the node-specific effect instance created from the assigned prefab.
    BlurEffect2DSharedPtr blurEffect = dynamic_pointer_cast<BlurEffect2D>(node2d->getEffect());
    // Set the MaskedProperty to true. Masked mode maintains the original alpha channel and
    // prevents the blur from spreading to fully transparent pixels.
    blurEffect->setMasked(true);

Member Data Documentation

PropertyType<float> kanzi::BlurEffect2D::RadiusProperty

static

Sets the amount of blur by defining the radius of the circular area of pixels that blend into each other.

The blur radius determines the distance in pixels that the blur expands the render area by extending outward from an edge, unless you set the MaskedProperty to true. To disable the blur effect, set to 0. The default value is 8.

See also: setRadius(), getRadius()

PropertyType<Quality> kanzi::BlurEffect2D::QualityProperty

static

Sets the visual quality of the blur effect.

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

See also: setQuality(), getQuality()

PropertyType<bool> kanzi::BlurEffect2D::MaskedProperty

static

Sets whether to blur only pixels with non-zero alpha values.

When enabled the blur does not spread to fully transparent pixels and the edges of the content stay sharp. The default value is false.

See also: setMasked(), getMasked()

float kanzi::BlurEffect2D::m_radius

protected

Cached radius for the blur effect.

Kanzi uses this to determine whether the effect is renderable.

The documentation for this class was generated from the following file:
