Documentation

shapeText :: Cursor -> StackContext a -> Text -> IO [PlacedRun] Source #

Perform text segmentation and shaping

The next step would be converting the

shape :: Cursor -> StackContext a -> ((?shapeContext :: ShapeContext) => IO ()) -> IO [PlacedRun] Source #

data Cursor Source #

Constructors

Cursor
Fields curX :: Float curY :: Float lineHeight :: Float Space between the baselines, as a multiple of the font size.
