Make the shape oval

[ussama7]

Hi, the library is working great. I was wondering if it's possible to make the circular shape (and so the related pulsing shapes on background) oval. I mean for example to make the shape width=100dp and height=70dp. I tried to set different widths and heights but it remains circular, taking the size of the smaller parameter set (in this it's transformed in a circle of 70dp x 70dp). Thanks in advance!
