Remarks

Contains methods to manipulate rectangles.

Unfortunately, C# often can't infer the type parameters. Many of these methods must be called with explicit type parameters.

static bool Loyc.Geometry.RectangleExt.Contains< Rect, Point, T > ( this Rect  a, Point  b  )

inlinestatic

Determines whether a rectangle contains a given point.

Returns false if the rectangle is not normalized.

Type Constraints

Point	:	IPointReader<T>
Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
Rect	:	Rect
Rect	:	T
T	:	IComparable<T>

static bool Loyc.Geometry.RectangleExt.Contains< Rect, T > ( this Rect  a, Rect  b  )

inlinestatic

Determines whether a rectangle fully contains another rectangle.

May not work correctly if either of the rectangles is not normalized.

Type Constraints

Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
Rect	:	Rect
Rect	:	T
T	:	IComparable<T>

static bool Loyc.Geometry.RectangleExt.ExpandToInclude< Rect, Point, T > ( this Rect  a, Point  b  )

inlinestatic

Expands a rectangle's boundaries to include a given point.

Returns

Returns true if the rectangle changed.

Type Constraints

Point	:	IPointReader<T>
Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
Rect	:	Rect
Rect	:	T
T	:	IComparable<T>

static bool Loyc.Geometry.RectangleExt.ExpandToInclude< Rect, Point, T > ( this Rect  a, IEnumerable< Point >  bs  )

inlinestatic

Expands a rectangle's boundaries to include a series of points.

Returns

Returns true if the rectangle changed.

Type Constraints

Point	:	IPointReader<T>
Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
Rect	:	Rect
Rect	:	T
T	:	IComparable<T>

static Rect Loyc.Geometry.RectangleExt.Intersect< Rect, T > ( this Rect  a, Rect  b  )

inlinestatic

Computes the intersection of two normalized rectangles, i.e. the region covered by both original rectangles.

The results may be incorrect if one or both rectangles are not normalized. If the rectangles do not overlap, a non-normalized rectangle is returned.

Type Constraints

Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
Rect	:	Rect
Rect	:	T
T	:	IComparable<T>

static bool Loyc.Geometry.RectangleExt.Overlaps< Rect, T > ( this Rect  a, Rect  b  )

inlinestatic

Determines whether a rectangle overlaps another rectangle.

May not work correctly if either of the rectangles is not normalized.

Type Constraints

Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
Rect	:	Rect
Rect	:	T
T	:	IComparable<T>

static Rect Loyc.Geometry.RectangleExt.Union< Rect, T > ( this Rect  a, Rect  b  )

inlinestatic

Computes the union of two normalized rectangles, i.e. a rectangle large enough to cover both original rectangles.

The results may be incorrect if one or both rectangles are not normalized.

Rect	:	IRectangleBase<T>
Rect	:	INewRectangle
