Detailed Description

SHAPE_LINE_CHAIN.

Represents a polyline (an zero-thickness chain of connected line segments). I purposedly didn't name it "polyline" to avoid confusion with the existing CPolyLine in pcbnew.

SHAPE_LINE_CHAIN class shall not be used for polygons!

PointInside()

bool SHAPE_LINE_CHAIN_BASE::PointInside ( const VECTOR2I &  aPt, int  aAccuracy = 0, bool  aUseBBoxCache = false  ) const

inherited

Function PointInside()

Checks if point aP lies inside a polygon (any type) defined by the line chain. For closed shapes only.

Parameters

aPt	point to check
aUseBBoxCache	gives better peformance if the bounding box caches have been generated.

Returns

true if the point is inside the shape (edge is not treated as being inside).

To check for interior points, we draw a line in the positive x direction from the point. If it intersects an even number of segments, the point is outside the line chain (it had to first enter and then exit). Otherwise, it is inside the chain.

Note: slope might be denormal here in the case of a horizontal line but we require our y to move from above to below the point (or vice versa)

Note: we open-code CPoint() here so that we don't end up calculating the size of the vector number-of-points times. This has a non-trivial impact on zone fill times.
