Create drawing

Hello

I have a simply problem, but I guess the solution will be not simple...

I have an image on a Page
<Image x:Name="testImage" Source="testImage"></Image>

And I would like to put a drawed layer (some shapes) to testImage with opacity so the testImage would be lower and the layer would be the upper. But I should make new image or drawing or bitmap, beacuse the layer is not a file.. But I don't know how I should do this?

I think I should create a bitmap, after then I should draw some shape, and after then how can I put this bitmap onto the testImage?

I tried the next:

Android.Graphics.Bitmap bitmap = Android.Graphics.Bitmap.CreateBitmap(200, 100, Bitmap.Config.Argb8888);
Xamarin.Forms.Image img = new Xamarin.Forms.Image();

but img.Source = bitmap is not ok, beacuse img.Source would be an ImageSource instance, but where is the conversion between bitmap and ImageSource?

If you are know javascript there is the canvas tag, and I can put a canvas onto an existed div . (for example)

Thank you very much.
