iOS Question Google maps marker modification

[rboeck]

In B4A i was able to change a bitmap and add a number, before i used this bitmap for a marker.

In B4I i tried this code:

Dim Bitm As B4XBitmap = LoadBitmap(File.DirAssets,"Markerg.png")
    Cv.Initialize(Bitm)
    Cv.DrawCircle(25dip,39dip,14dip,Colors.DarkGray,True,0)
    Dim f As Font=Font.CreateNewBold(14)
    Cv.DrawText("1",25dip, 45dip, f,Colors.Yellow,"CENTER")
    m1= gmap.AddMarker3(48.54, 16.132, "Marker Nr.1", Bitm)

but i got this error: Expected: UIView, object type: UIImage
So my question: is it possible and which type of object has to be used?

You are not using Canvas correctly.

Code to create a B4XCanvas:

Public Sub CreateCanvas (width1 As Int, height1 As Int) As B4XCanvas
   Dim iv As ImageView
   iv.Initialize("")
   iv.SetLayoutAnimated(0, 1, 0, 0, width1, height1)
   Dim c As B4XCanvas
   c.Initialize(iv)
   Return c
End Sub

You should then draw the bitmap, draw the other stuff, call Cv.Invalidate and get the bitmap with Cv.CreateBitmap.
Then release the canvas with Cv.Release (unless you want to keep it and use it again).
