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

◆ filterPath()
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.

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 |

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.

Returns the name of the object's class.
Implemented in SkDrawable.
◆ Make()
radius must be > 0 to have an effect.
It specifies the distance from each corner that should be "rounded".
◆ MakeCompose()
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()
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)

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.
