Arguments: stream
Returns the line height of the argument. The line height is the number of pixels taken up by a line of text, from the baseline of one line to the baseline of the next.
Note: incompatible change in release 6.0: in releases prior
to 6.0, when a frame-with-single-child
instance
was passed to this operator, the operator was actually applied to the
child (the result of applying frame-child to the
frame-with-single-child instance). In release 6.0, this redirection no
longer occurs. If you intend this operator to apply to the
frame-child, pass that to this operator rather than the parent. This
is a non-backward-compatible-change. See the release notes for more
information.
