Graphics, Figures & Tables ⇒ Tree in a scaled Bracket

[lericjee]

I try to enclose my syntax tree in a growing double bracket using \left \llbracket ... \right \rrbracket. However, the tree always sits in the lower half and leaving the upper half blank, which is very ugly. What's more, I cannot make the angle bracket grow with the tree.

Code: Select all

\documentclass{article}
\usepackage{stmaryrd}
\usepackage{qtree}
\usepackage{tikz-qtree}
\begin{document}

$\left \llbracket \textbf{\Tree [.S [.S [ [.NP [.N Ann ] ] [.VP [.V smokes ] ] ] ] and [.S [ [.NP [.N John ] ] [.VP [.V drinks ] ] ] ] ]} \right \rrbracket$ \\
$\left \langle \left ( \Tree [.S [.NP [.N Ann ] ] [.VP [.V smokes ] ] ] \right ) \right \rangle$

\end{document}
