makeRect :: forall a. a -> a -> a -> a -> Rect a

Constructs a Rect from four values

length :: forall p. ToPos Number p => p -> Number

Get the length of a position vector

diagonal :: forall s. ToSize Number s => s -> Number

Get the diagonal of a size

inside :: forall n p r. ToRegion n r => ToPos n p => Ord n => Semiring n => r -> p -> Boolean

Checks if a position is inside a region. Size of the region should be positive. Inclusive on the lower bound, exclusive on the higher bound.

outside :: forall n p r. ToRegion n r => ToPos n p => Ord n => Semiring n => r -> p -> Boolean

inside, but with its result negated.

putInsideMod :: forall n p r. ToRegion n r => AsPosEndo n p => EuclideanRing n => r -> p -> p

Put a position inside a region by using the modulus operator

area :: forall n s. ToSize n s => Semiring n => s -> n

Get the area of a size

perimeter :: forall n s. ToSize n s => Semiring n => s -> n

Get the perimeter of a size

ratio :: forall n s. ToSize n s => EuclideanRing n => s -> n

Get the ratio of a size by dividing the width by the height

midPos :: forall n p s. ToRegion n s => FromPos n p => EuclideanRing n => s -> p

Get the center position of a region

dot :: forall n p. ToPos n p => Semiring n => p -> p -> n

Get the dot product of two vectors

perpendicular :: forall n p. ToPos n p => Semiring n => Eq n => p -> p -> Boolean

Check if two vectors are perpendicular

parallel :: forall n p. ToPos n p => EuclideanRing n => Eq n => p -> p -> Boolean

Check if two vectors are parallel

toRectangleWith :: forall r n. ToRegion n r => Semiring n => (n -> Number) -> r -> Rectangle

Turn a region into a Rectangle

toRectangle :: forall r. ToRegion Number r => r -> Rectangle

Turn a rection represented with Numbers into a Rectangle
