Detailed Description

SkCornerPathEffect is a subclass of SkPathEffect that can turn sharp corners into various treatments (e.g. rounded corners)

Member Typedef Documentation

◆ Factory

typedef sk_sp<SkFlattenable>(* SkFlattenable::Factory) (SkReadBuffer &)

inherited

Member Enumeration Documentation

◆ DashType

enum SkPathEffect::DashType

inherited

If the PathEffect can be represented as a dash pattern, asADash will return kDash_DashType and None otherwise.

If a non NULL info is passed in, the various DashInfo will be filled in if the PathEffect can be a dash pattern. If passed in info has an fCount equal or greater to that of the effect, it will memcpy the values of the dash intervals into the info. Thus the general approach will be call asADash once with default info to get DashType and fCount. If effect can be represented as a dash pattern, allocate space for the intervals in info, then call asADash again with the same info and the intervals will get copied in.

Enumerator
kNone_DashType	ignores the info parameter
kDash_DashType	fills in all of the info parameter

Does applying this path effect to 'src' yield a set of points? If so, optionally return the points in 'results'.

◆ computeFastBounds()

Compute a conservative bounds for its effect, given the src bounds.

The baseline implementation just assigns src to dst.

◆ filterPath()

bool SkPathEffect::filterPath	(	SkPath *	dst,

inherited

Given a src path (input) and a stroke-rec (input and output), apply this effect to the src path, returning the new path in dst, and return true.

If this effect cannot be applied, return false and ignore dst and stroke-rec.

The stroke-rec specifies the initial request for stroking (if any). The effect can treat this as input only, or it can choose to change the rec as well. For example, the effect can decide to change the stroke's width or join, or the effect can change the rec from stroke to fill (or fill to stroke) in addition to returning a new (dst) path.

If this method returns true, the caller will apply (as needed) the resulting stroke-rec to dst and then draw.

◆ flatten()

void SkCornerPathEffect::flatten ( SkWriteBuffer & ) const

overrideprotectedvirtual

Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).

DEPRECATED public : will move to protected ... use serialize() instead

Reimplemented from SkFlattenable.

◆ getFactory()

virtual Factory SkFlattenable::getFactory ( ) const

pure virtualinherited

Implement this to return a factory function pointer that can be called to recreate your class given a buffer (previously written to by your override of flatten().

Implemented in SkDrawable.

◆ GetFlattenableType()

static SkFlattenable::Type SkPathEffect::GetFlattenableType ( )

◆ getFlattenableType()

SkFlattenable::Type SkPathEffect::getFlattenableType ( ) const

inlineoverridevirtualinherited

Implements SkFlattenable.

◆ getTypeName()

virtual const char* SkFlattenable::getTypeName ( ) const

pure virtualinherited

Returns the name of the object's class.

Implemented in SkDrawable.

◆ Make()

static sk_sp<SkPathEffect> SkCornerPathEffect::Make ( SkScalar radius )

inlinestatic

radius must be > 0 to have an effect.

It specifies the distance from each corner that should be "rounded".

◆ MakeCompose()

static sk_sp<SkPathEffect> SkPathEffect::MakeCompose	(	sk_sp< SkPathEffect >	outer,
		sk_sp< SkPathEffect >	inner
	)

staticinherited

Returns a patheffect that applies the inner effect to the path, and then applies the outer effect to the result of the inner's.

result = outer(inner(path))

◆ MakeSum()

static sk_sp<SkPathEffect> SkPathEffect::MakeSum	(	sk_sp< SkPathEffect >	first,
		sk_sp< SkPathEffect >	second
	)

staticinherited

Returns a patheffect that apples each effect (first and second) to the original path, and returns a path with the sum of these.

result = first(path) + second(path)

Implements SkPathEffect.

◆ ref()

void SkRefCntBase::ref ( ) const

Increment the reference count.

Must be balanced by a call to unref().

static void SkFlattenable::Register	(	const char	name[],
		Factory
	)

static void SkPathEffect::RegisterFlattenables ( )

◆ serialize() [1/2]

◆ serialize() [2/2]

size_t SkFlattenable::serialize	(	void *	memory,
		size_t	memory_size,
		const SkSerialProcs *	= `nullptr`
	)		const

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.

◆ 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.
