Diagrams.Backend.Postscript

A Postscript rendering backend for diagrams.

To build diagrams for Postscript rendering use the Postscript type in the diagram type construction

d :: Diagram Postscript R2
d = ...

and render giving the Postscript token

renderDia Postscript (PostscriptOptions "file.eps" (Width 400) EPS) d

This IO action will write the specified file.

Backend token

data Postscript

This data declaration is simply used as a token to distinguish this rendering engine.

Postscript-specific options

Unfortunately, Haddock does not yet support documentation for associated data families, so we must just provide it manually. This module defines

data family Options Postscript R2 = PostscriptOptions
          { psfileName     :: String       -- ^ the name of the file you want generated
          , psSizeSpec     :: SizeSpec2D   -- ^ the requested size of the output
          , psOutputFormat :: OutputFormat -- ^ the output format and associated options
          }

Postscript-supported output formats

data OutputFormat

Postscript only supports EPS style output at the moment. Future formats would each have their own associated properties that affect the output.
