Replace your DrawableFillOpacity() statement with
  • Img.fillColor("transparent");
to draw a non-opaque circle.

Im is attempting to fill with the transparent color, however the image you created does not have an alpha channel to handle a transparent color.

As "none" is actually fully-transparent black, the fill color comes out as black.

To fix add a -matte option before your -draw to ensure the image has a transparent channel. Or set the canvas with a color containing transparency
for example: xc:none or xc:#FF000000


I am not sure how you do this in an API.
