At the moment, this is not possible. ImageJ uses AWT, which does not allow
transparent components.

Re: ImageCanvas transparency

You could just use the java.awt.Image, obtained from the
ImagePlus.getImage, and paint it with transparency by setting the alpha
in the Graphics object of your Component.
To paint ROIs same thing: get it from the ImagePlus.getRoi() and call
paint on it passing your Graphics object.
