Region.Spanerator

class Spanerator

Returns the line segment ends within Region that intersect a horizontal line.

Methods

__init__	Sets Region.Spanerator to return line segments in Region on scan line.
next	Advances iterator to next span intersecting Region within line segment provided in constructor.

Methods

Spanerator.__init__(self: skia.Region.Spanerator, region: skia.Region, y: int, left: int, right: int) → None

Sets Region.Spanerator to return line segments in Region on scan line.

Parameters:

• region (skia.Region) – Region to iterate

• y (int) – horizontal line to intersect

• left (int) – bounds of iteration

• right (int) – bounds of iteration

Returns:

Region iterator

Spanerator.next(self: skia.Region.Spanerator, left: int, right: int) → bool

Advances iterator to next span intersecting Region within line segment provided in constructor.

Returns true if interval was found.

Parameters:

• left (int) – pointer to span start; may be nullptr

• right (int) – pointer to span end; may be nullptr

Returns:

true if interval was found
