Member Function Documentation

◆ begin()

virtual SkScalar Sk1DPathEffect::begin ( SkScalar contourLength ) const

protectedpure virtual

Called at the start of each contour, returns the initial offset into that contour.

Implemented in SkPath1DPathEffectImpl.

◆ computeFastBounds()

bool Sk1DPathEffect::computeFastBounds ( SkRect * ) const

inlineoverrideprivatevirtual

Implements SkPathEffectBase.

Definition at line 68 of file Sk1DPathEffect.cpp.

68{ return false; }

◆ next()

virtual SkScalar Sk1DPathEffect::next	(	SkPath *	dst,
		SkScalar	dist,
		SkPathMeasure &
	)		const

protectedpure virtual

Called with the current distance along the path, with the current matrix for the point/tangent at the specified distance. Return the distance to travel for the next call. If return <= 0, then that contour is done.

Implemented in SkPath1DPathEffectImpl.

◆ onFilterPath()

bool Sk1DPathEffect::onFilterPath	(	SkPath *	,
		const SkPath &	,
		SkStrokeRec *	,
		const SkRect *	,
		const SkMatrix &
	)		const

inlineoverrideprotectedvirtual

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.

Implements SkPathEffectBase.

Reimplemented in SkPath1DPathEffectImpl.

                SkScalar delta = this->next(dst, distance, meas);
                if (delta <= 0) {
                    break;
                }
                distance += delta;

        return true;
