Detailed Description

Apply a dash effect to the child geometry.

Follows the same semantics as SkDashPathEffect, with one minor tweak: when the number of intervals is odd, they are repeated once more to attain an even sequence (same as SVG stroke-dasharray: https://www.w3.org/TR/SVG11/painting.html#StrokeDasharrayProperty).

Implements sksg::GeometryNode.

◆ onContains()

Implements sksg::GeometryNode.

◆ onDraw()

Implements sksg::GeometryNode.

◆ onRevalidate()

SkRect sksg::GeometryEffect::onRevalidate ( InvalidationController *  ,
const SkMatrix &

Implements sksg::Node.

◆ ref()

void SkRefCntBase::ref ( ) const
inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

◆ revalidate()

const SkRect& sksg::Node::revalidate ( InvalidationController *  ,
const SkMatrix &   
)
inherited

◆ unique()

bool SkRefCntBase::unique ( ) const
inlineinherited

May return true if the caller is the only owner.

Ensures that all previous owner's actions are complete.

◆ unobserveInval()

void sksg::Node::unobserveInval ( const sk_sp< Node > &  )
protectedinherited

◆ unref()

void SkRefCntBase::unref ( ) const
inlineinherited

Decrement the reference count.

If the reference count is 1 before the decrement, then delete the object. Note that if this is the case, then the object needs to have been allocated via new, and not on the stack.
