func ApplySettings ¶
func ApplySettings(settings frontend.TypesettingSettings, ih *FormattingStyles)

func ParseHorizontalAlign ¶
func ParseHorizontalAlign(align string, styles *FormattingStyles) frontend.HorizontalAlignment
ParseHorizontalAlign parses the input ("left","center") and returns the HorizontalAlignment value.
func ParseRelativeSize ¶
func ParseRelativeSize(fs string, cur bag.ScaledPoint, root bag.ScaledPoint) bag.ScaledPoint
ParseRelativeSize converts the string fs to a scaled point. This can be an absolute size like 12pt but also a size like 1.2 or 2em. The provided dflt is the source size. The root is the document's default value.
func ParseVerticalAlign ¶
