cairoFontMapGetDefault :: IO FontMapgtk3 Graphics.UI.Gtk.Cairo Retrieve the default FontMap that contains a list of available fonts.
- One purpose of creating an explicit FontMap is to set a different scaling factor between font sizes (in points, pt) and Cairo units (in pixels). The default is 96dpi (dots per inch) which corresponds to an average screen as output medium. A 10pt font will therefore scale to 10pt * (1/72 pt/inch) * (96 pixel/inch) = 13.3 pixel.
cairoFontMapGetResolution :: FontMap -> IO Doublegtk3 Graphics.UI.Gtk.Cairo Ask for the scaling factor between font size and Cairo units.
- Value is in dots per inch (dpi). See cairoFontMapGetDefault.
cairoFontMapSetResolution :: FontMap -> Double -> IO ()gtk3 Graphics.UI.Gtk.Cairo Set the scaling factor between font size and Cairo units.
- Value is in dots per inch (dpi). See cairoFontMapGetDefault.
