computeCornerTangentControlPoint()

static VECTOR2I computeCornerTangentControlPoint ( const VECTOR2I & aAnchor, const VECTOR2I & aCornerCenter, double aBias, const VECTOR2I & aDesiredDir )

static

Helper to compute a control point for a teardrop anchor on a rounded rectangle corner.

The control point is placed along the tangent to the corner arc at the anchor point, in the direction that best aligns with the desired direction (typically toward the track).

Parameters

aAnchor	the anchor point on the pad edge
aCornerCenter	the center of the corner arc
aBias	the distance from the anchor to place the control point
aDesiredDir	the direction we want the control point to go (toward track)

Returns

the computed control point

isPointOnOvalEnd()

static bool isPointOnOvalEnd ( const VECTOR2I & aPoint, const VECTOR2I & aPadPos, const VECTOR2I & aPadSize, const EDA_ANGLE & aRotation, VECTOR2I & aArcCenter )

static

Check if a point is on the curved (semicircular) end of an oval pad.

An oval is a stadium shape with semicircular caps on the ends of the minor axis.

Parameters

aPoint	the point to check
aPadPos	the pad center position
aPadSize	the pad size (width, height)
aRotation	the pad rotation
aArcCenter	[out] if on curved end, receives the semicircle center

Returns

true if point is on a curved end of the oval

isPointOnRoundedCorner()

static bool isPointOnRoundedCorner ( const VECTOR2I & aPoint, const VECTOR2I & aPadPos, const VECTOR2I & aPadSize, int aCornerRadius, const EDA_ANGLE & aRotation, VECTOR2I & aCornerCenter )

static

Check if a point is within a rounded corner region of a rounded rectangle pad.

Returns true if the point is in a corner arc region and provides the corner center.

Parameters

aPoint	the point to check
aPadPos	the pad center position
aPadSize	the pad size (width, height)
aCornerRadius	the corner radius
aRotation	the pad rotation
aCornerCenter	[out] if in corner, receives the corner arc center

Returns

true if point is in a corner arc region

static VECTOR2D NormalizeVector ( const VECTOR2I & aVector )

static

Returns
