You could just draw the rectange with a 50% transparent white.

Current that is specified as -fill '#FFFFFF80'

For an example see Annotation Images, Label Overlays... ... /#label_on

Their is a request however to allow something like a white_50%
specification for colors, or at least something along those lines, but it
is still under discussion.
