rectangle :: Point -> Point -> Image Source

Draw an axis-aligned rectangle with the given opposite corners.

type Length = Scalar Source

type Angle = Scalar Source

triangle :: Length -> Length -> Length -> Image Source

Draw a triangle with the given side lengths. The corner opposite the third side is located at the origin and the first side is drawn along the x-axis.

triangleA :: Length -> Length -> Angle -> Image Source

Draw a triangle given by two side lengths and an angle. The corner of the angle is drawn at the origin and the first side along the x-axis.

triangleAA :: Length -> Angle -> Angle -> Image Source

Draw a triangle given by two angles and the length of the side shared by the angles. The first angle is drawn at the origin and the side along the x-axis.

regularPoly :: Int -> Image Source

Draw an n-sided regular polygon centered at the origin and one corner at unitY.

angleArc Source

Arguments

:: Scalar	Radius of the arc in pixels
-> Point	A
-> Point	B
-> Point	C
-> Image

Draw an angle arc for the counter clockwise angle BAC.

labelledAngle Source

Arguments

:: String
-> Vec	Position of the text relative to the angle
-> Point
-> Point
-> Point
-> Image

Draw an angle arc labelled by the given string.

arrow :: Point -> Point -> Image Source

Draw a line segment with an arrow head.
