Hi to All
my problem is that I would like to draw a simbol centered at a given Marker, in a GoogleMaps map. For example, let's assume that the symbol is a rectangle. I use a canvas to draw the rectangle in a Bitmap. The code was written by Erel in another post, for drawing a text on a marker, and I report it hereunder, modified for my needs, just drawing a rectangle:
With this code, the rectangle is drawn centered on X, with respect to marker position, but "above" the Marker, as shown in the attached image (44.png)
The yellow line connects Markers positions. What I am not able to do, is to draw a rectangle centered at the Marker position. I begin to think that I must change the following AddMarker3 call, using Latitude and Longitude modified to shift the rectangle with respect to the marker position. This seems a rather tricky solution, because the offsets are in meters.
The function CreateBitmap is called with:

Dim c As B4XCanvas
font=xui.CreateDefaultFont(20) ' just used for getting a suitable size
larg=text.Length*font.Size
alt=font.Size
p.SetLayoutAnimated(0, 0, 0, larg, alt)
c.Initialize(p)
c.DrawRect(c.TargetRect,colore,False,2)
Return c.CreateBitmap
