Instances
fo_fonts :: Lens' FileOptions (IO (FontSelector Double)) #
renderableToFile :: FileOptions -> FilePath -> Renderable a -> IO (PickFn a) #
Generate an image file for the given renderable, at the specified path. Size, format,
and text rendering mode are all set through the FileOptions parameter.
toFile :: (Default r, ToRenderable r) => FileOptions -> FilePath -> EC r () -> IO () #
Generate an image file from from the state content of an EC
computation. The state may have any type that is an instance of
ToRenderable
cBackendToFile :: FileOptions -> BackendProgram a -> FilePath -> IO a #
Generate an image file for the given drawing instructions, at the specified path. Size and
format are set through the FileOptions parameter.
Fonts
loadSansSerifFonts :: forall n. (RealFloat n, Read n) => IO (FontSelector n) #
Load sans-serif fonts only
loadCommonFonts :: forall n. (RealFloat n, Read n) => IO (FontSelector n) #
Load serif, sans-serif and monospace fonts.
type FontSelector n = FontStyle -> PreparedFont n #
