paragraphMap :: (b -> b') -> Paragraph (a, b, c) -> Paragraph (a, b', c) Source #

layoutMap :: (b -> b') -> ParagraphLayout (a, b, c) -> ParagraphLayout (a, b', c) Source #
Apply an operation to the 2nd field of a laid-out paragraph's userdata, for it's entire subtree.
treeMap :: (b -> b') -> FragmentTree (a, b, c) -> FragmentTree (a, b', c) Source #
