Centering An Image On roImageCanvas

I’m working with the roImageCanvas for the first time today, and am using it as a “Screen Facade” as recommended in the Developer Guidelines handbook. I’d like to center an image on the roImageCanvas, but am having issues getting it to do this.

    screenFacade = CreateObject("roImageCanvas")
    screenFacade.SetLayer(0,{Color:"#FF000000", CompositionMode:"Source"})
    canvasItems = [
                    { 
                        url:"pkg:/images/Splash/Splash.png"
                        TargetRec:{x:390, y:357, w:400, h:200}
                    }
                    {
                        Text:"Loading..."
                        TextAttrs:{
                                    Color:"#FF0000", 
                                    Font:"Medium",
                                    HAlign:"HCenter",
                                    VAlign:"VCenter",
                                    Direction:"LeftToRight"
                                  }
                    }
                  ]

    screenFacade.SetRequireAllImagesToDraw(true)
    screenFacade.SetLayer(1,canvasItems)
    screenFacade.Show()

No matter what I set in the “TargetRec” for my image, it is always displaying in the upper left corner of the monitor. What am I doing wrong and how do I center it?

Thanks all!!

TargetRect has a “t” on the end.

Ahh!! Great, silly mistake on my part. I was thinking wrong on how the “TargetRect” was used, thanks for the great catch Mark!
