customize the shape

Hi, I need to customize the shape of the clouds for displaying tags on maps.
Only <rect> is accepted inside the tag <shape> ? There are other ways to insert at least tilted rectangles with 4 pairs of coordinates? thank you very much

Hi Sergio. It is not intended that you generate those <rect> tags yourself.
Just create an image and do everything written on the guide (http://tagul.com/custom-shape-with-api)
