I\'m using a transparent PNG as my marker, and would like for the transparent area to be filled a certain color. I previously accomplished this using marker shadows, but tho
I have encountered the quite similar issue. I wish to convert my icon background to to transparent instead.

The following is the example of the icon with transparent output in google map. Hope it helps.
