Detailed Description

Use MaskEffect2D to apply a mask to 2D nodes.

Examples

To create a mask effect:

    // Create an effect template for the MaskEffect2D effect prefab.
    NodeEffectTemplate2DSharedPtr maskEffectTemplate =
        NodeEffectTemplate2D::create(MaskEffect2D::getStaticMetaclass()->getName(), "MaskEffect");
 
    // Create a node effect prefab from the effect template.
    NodeEffectPrefab2DSharedPtr maskEffectPrefab =
        NodeEffectPrefab2D::create(getDomain(), "MaskEffect prefab", maskEffectTemplate);

To set the mask effect properties:

    // Create an effect template.
    NodeEffectTemplate2DSharedPtr maskEffectTemplate =
        NodeEffectTemplate2D::create(MaskEffect2D::getStaticMetaclass()->getName(), "MaskEffect");
 
    // Set the value of the MaskProperty in the template.
    // The MaskProperty defines the mask texture which you must set before you can use the mask effect.
    TextureSharedPtr maskTexture = acquireMaskTexture(getDomain());
    maskEffectTemplate->addPropertyValue(MaskEffect2D::MaskProperty, Variant(maskTexture));
 
    // Create a mask effect prefab.
    NodeEffectPrefab2DSharedPtr maskEffectPrefab =
        NodeEffectPrefab2D::create(getDomain(), "MaskEffect prefab", maskEffectTemplate);
 
    // Assign the mask effect to a 2D node.
    node2d->setEffectPrefab(maskEffectPrefab);
 
    // Get the node-specific effect instance created from the assigned prefab.
    MaskEffect2DSharedPtr maskEffect = dynamic_pointer_cast<MaskEffect2D>(node2d->getEffect());
 
    // Set the mask stretch mode to uniform.
    maskEffect->setStretch(MaskEffect2D::Stretch::Uniform);

Member Data Documentation

◆ MaskProperty

PropertyType<ResourceSharedPtr> kanzi::MaskEffect2D::MaskProperty

static

Sets the mask texture.

The default value is no texture.

See also: setMask(), getMask()

◆ HeightProperty

PropertyType<float> kanzi::MaskEffect2D::HeightProperty

static

Overrides the mask texture height in pixels.

See also: setHeight(), getHeight()

◆ WidthProperty

PropertyType<float> kanzi::MaskEffect2D::WidthProperty

static

Overrides the mask texture width in pixels.

See also: setWidth(), getWidth()

◆ OffsetProperty

PropertyType<Vector2> kanzi::MaskEffect2D::OffsetProperty

static

Sets the mask offset along the X and Y axes in pixels.

Kanzi applies the mask offset after stretch, alignment, and scale. The default value is Vector2(0, 0).

See also: setOffset(), getOffset()

◆ ScaleProperty

PropertyType<Vector2> kanzi::MaskEffect2D::ScaleProperty

static

Sets the factor by which to scale the mask.

Kanzi applies the scale after stretch and alignment. The default value is Vector2(1, 1).

See also: setScale(), getScale()

◆ StretchProperty

PropertyType<Stretch> kanzi::MaskEffect2D::StretchProperty

static

Sets the stretch mode of the mask:

None disables stretching. This is the default.
Fill stretches the mask to fill the node.
Uniform stretches the mask using uniform scaling to fill the node in either vertical or horizontal direction, whichever requires smaller scale.
UniformToFill stretches the mask using uniform scaling to fill the node in either vertical or horizontal direction, whichever requires larger scale.

See also: setStretch(), getStretch()

◆ VerticalAlignmentProperty

PropertyType<VerticalAlignment> kanzi::MaskEffect2D::VerticalAlignmentProperty

static

Sets the vertical alignment of the mask:

Top aligns the top edge of the mask with the top edge of the node. This is the default.
Bottom aligns the bottom edge of the mask with the bottom edge of the node.
Center aligns the mask vertically to the center of the node.
Stretch stretches the mask vertically to fit the node from the top edge to the bottom edge.

See also: setVerticalAlignment(), getVerticalAlignment()

◆ HorizontalAlignmentProperty

PropertyType<HorizontalAlignment> kanzi::MaskEffect2D::HorizontalAlignmentProperty

static

Sets the horizontal alignment of the mask:

Left aligns the left edge of the mask with the left edge of the node. This is the default.
Right aligns the right edge of the mask with the right edge of the node.
Center aligns the mask horizontally to the center of the node.
Stretch stretches the mask horizontally to fit the node from the left edge to the right edge.

See also: setHorizontalAlignment(), getHorizontalAlignment()

◆ ScreenSpaceProperty

PropertyType<bool> kanzi::MaskEffect2D::ScreenSpaceProperty

static

Indicates whether to layout the mask relative to the screen.

See also: setScreenSpace(), getScreenSpace()

◆ ChannelProperty

PropertyType<Channel> kanzi::MaskEffect2D::ChannelProperty

static

Sets the mask texture channel to use as the input for the mask:

Alpha uses the alpha channel from the texture. This is the default.
Red uses the red color channel from the texture.
Green uses the green color channel from the texture.
Blue uses the blue color channel from the texture.
Luminance uses the luminance value calculated from the red, green, and blue color channels.

See also: setChannel(), getChannel()

◆ InvertProperty

PropertyType<bool> kanzi::MaskEffect2D::InvertProperty

static

Indicates whether to invert the mask.

The default value is false.

See also: setInvert(), getInvert()

◆ StrengthProperty

PropertyType<float> kanzi::MaskEffect2D::StrengthProperty

static

Sets the strength of the mask effect.

The range of the property is from 0 to 1 such that:

0 disables the mask effect.
1 applies the mask effect at full strength. This is the default.
Any other value between 0 and 1 partially applies the mask as if the non-masked result was blended with the fully masked version.
