Drawing text
textSVG :: (Read n, RealFloat n) => String -> n -> Path V2 n #
A short version of textSVG' with standard values. The Double value is the height.
import Graphics.SVGFonts textSVGExample = stroke $ textSVG "Hello World" 1
textSVG' :: RealFloat n => TextOpts n -> String -> Path V2 n #
Create a path from the given text and options. The origin is at the center of the text and the boundaries are given by the outlines of the chars.
import Graphics.SVGFonts
text' t = stroke (textSVG' (TextOpts lin INSIDE_H KERN False 1 1) t)
# fc blue # lc blue # bg lightgrey # fillRule EvenOdd # showOrigin
textPic0 = (text' "Hello World") # showOrigin
textSVG_ :: forall b n. (TypeableFloat n, Renderable (Path V2 n) b) => TextOpts n -> String -> QDiagram b V2 n Any #
Create a path from the given text and options. The origin is at the left end of the baseline of of the text and the boundaries are given by the bounding box of the Font. This is best for combining Text of different fonts and for several lines of text. As you can see you can also underline text by setting underline to True.
import Graphics.SVGFonts
text'' t = (textSVG_ (TextOpts lin INSIDE_H KERN True 1 1) t)
# fc blue # lc blue # bg lightgrey # fillRule EvenOdd # showOrigin
textPic1 = text'' "Hello World"
Options
Constructors
| INSIDE_H | The string fills the complete height, width adjusted. Used in text editors. The result can be smaller or bigger than the bounding box:
|
| INSIDE_W | The string fills the complete width, height adjusted. May be useful for single words in a diagram, or for headlines. The result can be smaller or bigger than the bounding box:
|
| INSIDE_WH | The string is stretched inside Width and Height boundaries. The horizontal advances are increased if the string is shorter than there is space. The horizontal advances are decreased if the string is longer than there is space. This feature is experimental and might change in the future.

Provided fonts
bit :: (Read n, RealFloat n) => PreparedFont n #
Bitstream, a standard monospaced font (used in gedit)
lin :: (Read n, RealFloat n) => PreparedFont n #
Linux Libertine, for non-monospaced text. http://www.linuxlibertine.org/ Contains a lot of unicode characters.
lin2 :: (Read n, RealFloat n) => PreparedFont n #
Linux Libertine, cut to contain only the most common characters. This results in a smaller file and hence a quicker load time.
