Functions

SEG KIGEOM::NormalisedSeg (const SEG &aSeg)
 Returns a SEG such that the start point is smaller or equal in x and y compared to the end point.
 
const VECTOR2IKIGEOM::GetOtherEnd (const SEG &aSeg, const VECTOR2I &aPoint)
 Get the end point of the segment that is not the given point.
 
OPT_VECTOR2I KIGEOM::GetSharedEndpoint (const SEG &aSegA, const SEG &aSegB)
 Get the shared endpoint of two segments, if it exists, or std::nullopt if the segments are not connected end-to-end.
 
std::array< SEG, 4 > KIGEOM::BoxToSegs (const BOX2I &aBox)
 Decompose a BOX2 into four segments.
 
std::vector< SEGKIGEOM::GetSegsInDirection (const BOX2I &aBox, DIRECTION_45::Directions aDir)
 Get the segments of a box that are in the given direction.
 
std::optional< SEGKIGEOM::ClipHalfLineToBox (const HALF_LINE &aRay, const BOX2I &aBox)
 Get the segment of a half-line that is inside a box, if any.
 
std::optional< SEGKIGEOM::ClipLineToBox (const LINE &aLine, const BOX2I &aBox)
 Get the segment of a line that is inside a box, if any.
 
SHAPE_ARC KIGEOM::MakeArcCw90 (const VECTOR2I &aCenter, int aRadius, DIRECTION_45::Directions aDir)
 Get a SHAPE_ARC representing a 90-degree arc in the clockwise direction with the midpoint in the given direction from the center.
 
SHAPE_ARC KIGEOM::MakeArcCw180 (const VECTOR2I &aCenter, int aRadius, DIRECTION_45::Directions aDir)
 Get a SHAPE_ARC representing a 180-degree arc in the clockwise direction with the midpoint in the given direction from the center.
 
VECTOR2I KIGEOM::GetPoint (const SHAPE_RECT &aRect, DIRECTION_45::Directions aDir, int aOutset=0)
 Get the point on a rectangle that corresponds to a given direction.
 
std::vector< TYPED_POINT2IKIGEOM::GetCircleKeyPoints (const CIRCLE &aCircle, bool aIncludeCenter)
 Get key points of an CIRCLE.
 

Detailed Description

Utility functions for working with shapes.

These are free functions to avoid bloating the shape classes with functions that only need to be used in a few places and can just use the public interfaces.
