◆ asPoints()

bool SkPathEffectBase::asPoints	(	PointData *	results,
		const SkPath &	src,

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

◆ getFlattenableType()

SkFlattenable::Type SkPathEffectBase::getFlattenableType ( ) const

inlineoverridevirtual

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.

Implements SkFlattenable.

Filter the input path.

The CTM parameter is provided for path effects that can use the information. The output of path effects must always be in the original (input) coordinate system, regardless of whether the path effect uses the CTM or not.

Implemented in Sk1DPathEffect, SkCornerPathEffectImpl, SkDashImpl, SkTrimPE, SkDiscretePathEffectImpl, Sk2DPathEffect, SkComposePathEffect, SkSumPathEffect, SkPath1DPathEffectImpl, and SkLine2DPathEffectImpl.

◆ onNeedsCTM()

Path effects requiring a valid CTM should override to return true.
