MBS Overlay center on screen

Add-Ons

Hi all, I am trying to use MBS overlay to center an image used as a splash/loading image on app open. Should be pretty straight forward, but have not had luck. It seemed to work before but then I changed the zoom settings on my laptop I think and started opening slightly to the top left corner. Any advice greatly appreciated!

splashOverlay.create

'set picture and mask 
//new picture
p = new Picture(128,150,32)

//picture and it's mask
dim pg as Graphics = p.Graphics
dim mg as Graphics = p.mask.Graphics

mg.ForeColor = &cFFFFFF
mg.FillRect 0, 0, p.Width, p.Height

Dim iconPict As Picture
Dim iconMask As Picture

Dim mbPict As MemoryBlock
Dim mbMask As MemoryBlock


If APP.IsLite = False Then //regular 
  mbPict = APP.streetImage
  
Else
  mbPict = App.StreetLiteImage
end

mbMask = App.StreetImageMask

iconPict = Picture.FromData( DecodeBase64( mbPict ) ) 
iconMask = Picture.FromData( DecodeBase64( mbMask ) ) 

pg.DrawPicture IconPict,0,0
mg.DrawPicture IconMask,0,0


'create new overlay
o=new MyOverlay( (Screen(0).Width - 128)/2 , (Screen(0).Height - 150)/2 ,128,150)

'apply picture to overlay
o.Pict = p

updateBar

o.Show
timer1.Mode=2

Mac? Win?

For Windows coordinates are passed to OS as is.
So for high DPI, you need to multiply them yourself with factor.

Thanks Christian. It is Windows. Really surprised I’ve only just noticed that now, I wonder what other images are all wonky on my apps. Anyway, fixed by multiplying the overlay width and height by TrueWindow.ScaleFactor.

o=new MyOverlay( TrueWindow.ScaleFactor * (Screen(0).Width - 128)/2 , TrueWindow.ScaleFactor * (Screen(0).Height - 150)/2 ,128,150)
