Polygons with hole inside

Hello everyone,

I have an application that allows me to draw and manipulate all kind of shapes. Now i would like to be abble to draw a polygon with an hole in it.
Can anyone help me with that?

Thanks in advance, sebastien.

You can have shape with hole using <path> element.
You describe outline with M .... and inner with M .... but in other direction.
A sample :
<path d="M50 50h200 v200 h-200z M100 100 v50 h50 v-50z" fill="red"/>
If you want to get this shape in your application, you can let user draw two polygons, but you have to manage outline and innerline ...
