What does a "white-on-transparent" image mean?

Question

Reading Android's new instructions to adapt my app icon (in a status bar), I am stuck on this:

Notification icons should only be a white-on-transparent background image.

What does it mean a "white-on-transparent background image"?

Basically, I currently own a .PNG image with the icon of my app (not transparent).

This means the icon should have a white color for any lines/shapes that your icon has and be transparent in all other areas.

@Mik378 For that image, just make the blue transparent and it should be fine

No need to touch on the "W" ?
