SVGFonts-1.7.0.1: Fonts from the SVG-Font format

Native font support for the diagrams framework (http://projects.haskell.org/diagrams/). Note that this package can be used with any diagrams backend, not just the SVG backend. The SVG-font format is easy to parse and was therefore chosen for a font library completely written in Haskell.

You can convert your own font to SVG with http://fontforge.github.io/, or use the included LinLibertine and Bitstream fonts.

Features:

• Complete implementation of the features that Fontforge produces (though not the complete SVG format)
• Kerning (i.e. the two characters in "VA" are closer than the characters in "VV")
• Unicode
• Ligatures
• An example that shows how to do text boxes with syntax highlighting using highlighting-kate: http://hackage.haskell.org/package/highlighting-kate

XML speed issues can be solved by trimming the svg file to only those characters that are used (or maybe binary xml one day).

Version 1.0 of this library supports texturing, though this only makes sense in a diagrams backend that does rasterization in Haskell, such as diagrams-rasterific.

Example:

 # LANGUAGE NoMonomorphismRestriction #

main = do linLibertine <- loadDataFont "fonts/LinLibertine.svg"
          t <- text'''' linLibertine "Hello"
          mainWith (t :: Diagram B)

text'   font t = stroke (textSVG t 1) # fc purple # fillRule EvenOdd
text''  font t = stroke (textSVG' (TextOpts font INSIDE_H KERN False 1 1) t) # fillRule EvenOdd
text''' font t =        (textSVG_ (TextOpts font INSIDE_H KERN True  1 1) t) # fillRule EvenOdd

-- using a local font
text'''' font t = do
   font <- loadFont "/path/to/font.svg"
   return $ stroke (textSVG' (TextOpts font INSIDE_H KERN False 1 1) t)
