How to convert bitmapDescriptor to bitmap?

Feature I am trying to implement is: enlarge marker with specific icon if it is the closest one to user's selected area. I store all markers in one collection collectionOfMarkers() and findClosest() method returns marker that is closest to user's area.

// Get closes marker
        closestMarker= getClosestItem(collectionOfMarkers(),latLng);
        mClusterRenderer.getMarker(closestMarker).setIcon(closestMarker.getIcon());

To resize that one marker I would need to pass new Bitmap with specified width and height parameters, however it also would need Bitmap source and I only have bitmapDescriptor from doing closestMarker.getIcon(). Is there a way to convert BitmapDescriptor to Bitmap? I do not have icon name or resource path, as there are multiple icons that marker could represent from, thus, it has to be extracted from marker itself.

public Bitmap resizeMapIcons(String iconName,int width, int height){
    Bitmap imageBitmap = BitmapFactory.decodeResource(getResources(),getResources().getIdentifier(iconName, "drawable", getPackageName()));
    Bitmap resizedBitmap = Bitmap.createScaledBitmap(imageBitmap, width, height, false);
    return resizedBitmap;
}

Use it like 

googleMap.addMarker(new MarkerOptions()
            .title("New Marker")
            .snippet("Check out this place.")
            .position(chelsea).icon(BitmapDescriptorFactory.fromBitmap(resizeMapIcons("image_name",100,100))));
