Android Question How to add drop shadow effect to bitmap?

[Inman]

Is it possible to add a drop shadow effect to a bitmap file or onto the Imageview holding it? What makes it particularly tough in my case is that the image is circular shaped and not rectangular.

I found some code here. Could you please take a look and see if this can be achieved with B4A?

Look through the image getting the value of each pixel, obtain the alpha of each pixel, draw that alpha as a shade of grey (r,g,b all have the same value) to a second image. Then draw the second one under the first one
