applyHeights :: Traversable t => [Int] -> t Window -> t Window Source

strokePicture :: [Span (Endo a)] -> [(Point, a -> a)] Source

Turn a sequence of (from,style,to) strokes into a sequence of picture points (from,style), taking special care to ensure that the points are strictly increasing and introducing padding segments where neccessary. Precondition: Strokes are ordered and not overlapping.

paintStrokes :: (a -> a) -> a -> [(Point, a -> a)] -> [(Point, a)] -> [(Point, a)] Source

Paint the given stroke-picture on top of an existing picture

paintPicture :: a -> [[Span (Endo a)]] -> [(Point, a)] Source

attributesPictureB :: UIStyle -> Maybe SearchExp -> Region -> [[Span StyleName]] -> BufferM [(Point, Attributes)] Source

attributesPictureAndSelB :: UIStyle -> Maybe SearchExp -> Region -> BufferM [(Point, Attributes)] Source
