erase a shape

Hi, Inquisit 5 community
I wish to ask whether it is possible to just erase a shape by removing it (transparently) and without adding extra color?
My background stimulus is a picture, and I wish to erase the dot without adding other colors to the picture.

<shape dot>
/ color = red
/ shape = circle
/ erase = true()
/ position = (values.ax,values.ay)
/ size = (10,10)
</shape>

Thank you for your attention;

You would not erase the shape in this case. Instead, you would re-draw the picture to the screen (per /stimulustimes or -frames, per /responsemessage, whatever is applicable in your particular case).
