Detailed Description

This path effect chops a path into discrete segments, and randomly displaces them.

Make()

sk_sp< SkPathEffect > SkDiscretePathEffect::Make ( SkScalar  segLength, SkScalar  dev, uint32_t  seedAssist = 0  )

static

Break the path into segments of segLength length, and randomly move the endpoints away from the original path by a maximum of deviation. Note: works on filled or framed paths

Parameters

seedAssist

This is a caller-supplied seedAssist that modifies the seed value that is used to randomize the path segments' endpoints. If not supplied it defaults to 0, in which case filtering a path multiple times will result in the same set of segments (this is useful for testing). If a caller does not want this behaviour they can pass in a different seedAssist to get a different set of path segments.
