Constructing path-based diagrams

Description

Paths in two dimensions are special since we may stroke them to create a 2D diagram, and (eventually) perform operations such as intersection and union.

Synopsis

Constructing path-based diagrams

stroke :: Renderable (Path R2) b => Path R2 -> Diagram b R2 Source

Convert a path into a diagram. The resulting diagram has the names 0, 1, ... assigned to each of the path's vertices.

Note that a bug in GHC 7.0.1 causes a context stack overflow when inferring the type of stroke. The solution is to give a type signature to expressions involving stroke, or (recommended) upgrade GHC (the bug is fixed in 7.0.2 onwards).

strokeT :: Renderable (Path R2) b => Trail R2 -> Diagram b R2 Source

A composition of stroke and pathFromTrail for conveniently converting a trail directly into a diagram.

Note that a bug in GHC 7.0.1 causes a context stack overflow when inferring the type of stroke and hence of strokeT as well. The solution is to give a type signature to expressions involving strokeT, or (recommended) upgrade GHC (the bug is fixed in 7.0.2 onwards).
