Hello,

I am trying to figure this out for weeks, and I am lost. 

I have my original image:  https://www.dropbox.com/s/ni1jiik9q936131/help1.png?dl=0

Which has a transparent inside since it’s used for a bouncing ball.

I applied an effect button to it.  (or any other effect)

To get this:    https://www.dropbox.com/s/bjd9l5vr35a97ve/help2.png?dl=0

But I am losing my transparency.

Even in my other program, I selected  Grey as transparency.  It’s still not working.

So  how can I fill it with an effect,  that it’s only doing the blue part, and not the inside of it?

Or  how can I make the Grey part  transparent in Inkscape?

Thank you so much
