GI.Pango.Structs.FontMetrics
Contents
Description
A #PangoFontMetrics structure holds the overall metric information for a font (possibly restricted to a script). The fields of this structure are private to implementations of a font backend. See the documentation of the corresponding getters for documentation of their meaning.
- newtype FontMetrics = FontMetrics (ForeignPtr FontMetrics)
- noFontMetrics :: Maybe FontMetrics
- fontMetricsGetApproximateCharWidth :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetApproximateDigitWidth :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetAscent :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetDescent :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetStrikethroughPosition :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetStrikethroughThickness :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetUnderlinePosition :: MonadIO m => FontMetrics -> m Int32
- fontMetricsGetUnderlineThickness :: MonadIO m => FontMetrics -> m Int32
- fontMetricsNew :: MonadIO m => m FontMetrics
