Standard arrowheads and tails. Each arrowhead or tail is designed to be drawn filled, with a line width of 0, and is normalized to fit inside a circle of diameter 1.



Standard arrowheads

Configurable arrowheads

Creates arrowheads of the same shape as the standard heads but where the angle parameter is used to specify the angle to the top left point of the arrowhead.

arrowheadTriangle :: Angle -> ArrowHT Source

Isoceles triangle style. The above example specifies an angle of `2/5 Turn`.

arrowheadDart :: Angle -> ArrowHT Source

Isoceles triangle with linear concave base. Inkscape type 1 - dart like.

arrowheadSpike :: Angle -> ArrowHT Source

Isoceles triangle with curved concave base. Inkscape type 2.

arrowheadThorn :: Angle -> Double -> ArrowHT Source

Curved sides, linear concave base. Illustrator CS5 #3

Arrow tails

Standard arrow tails

Configurable arrow tails

arrowtailQuill :: Angle -> ArrowHT Source

The angle is where the top left corner intersects the circle.
