# Arrowheads

## 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 -> ArrowHTSource

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

arrowheadDart :: Angle -> ArrowHTSource

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

arrowheadSpike :: Angle -> ArrowHTSource

Isoceles triangle with curved concave base. Inkscape type 2.

arrowheadThorn :: Angle -> Double -> ArrowHTSource

Curved sides, linear concave base. Illustrator CS5 #3

# Arrow tails

## Standard arrow tails

## Configurable arrow tails

arrowtailQuill :: Angle -> ArrowHTSource

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