It is shown that the singular values of the operator $aP\,-\,Pa$, where $P$ is Bergman's projection over a bounded domain $\Omega $ and $a$ is a function analytic on $\bar{\Omega }$, detect the length of the boundary of $a\left( \Omega \right)$. Also we point out the relation of that operator and the spectral asymptotics of a Hankel operator with an anti-analytic symbol.
