I know there is a Notebook option WindowOpacity can be used to adjust the opacity of a whole notebook. But what I want is keeping the text and graphics and so on being Opacity[1] while the other parts of the window being Opacity[0.3], which may look like (the pic is roughly produced by photoshop):
I guess this effect might be achieved by capture the screen prior and set it as the background of a Cell/Cells. But even if that is applicable, it must be very inefficiency.
My questions are: how to achieve this transparent effect in Mathematica (maybe with some help from external applications)? and how to do it effectively?
Backgroundsays "The setting for Background can be any color or opacity specification" so I thought you could locally setOpacityat the cell level to override theWindowOpacityand get the sort of effect you want but I get an error message when I useOpacitywithBackground. – Mike Honeychurch Jan 19 '12 at 6:26Opacitysettings at the cell level are being overridden by theWindowOpacity. Interesting problem. – Mike Honeychurch Jan 19 '12 at 6:37
