Picture in a watchface

7276067

Hello,

and first of all - I know there are already several threads on this topic.

A Picture on a watchface. Done! - Discussion - Connect IQ - Garmin Forums

...

But they all didn't help me get mine running, so please let me ask for help cause I really can't see the fault.

I tried to stick to the altitude8k example but I just can't get it running

https://github.com/worksasdesigned/altitude8k

as soon as I add the resources.xml it doesn't work any more and putting the png file in the drawables folder,

listing it in the drawables.xml

         <drawables>
              <bitmap id="LauncherIcon" filename="launcher_icon.png" />
              <bitmap id="Picture" filename="everestline.png" />
        </drawables>

and calling it via

        dc.setColor(Gfx.COLOR_BLACK, Gfx.COLOR_BLACK);
        dc.clear();
       
        var picback = null;
        dc.setColor(Gfx.COLOR_WHITE, Gfx.COLOR_TRANSPARENT);
       
        picback = WatchUi.loadResource(Rez.Drawables.Picture);
        dc.drawBitmap(1, 42, picback);

only results in no errors accuring and the simulator is showing me the time but no image.

So please. Anybody any ideas?

Regards Marcus

    That's mayfull code of the viewfile. drawables you find above:

    using Toybox.Graphics as Gfx;
    import Toybox.Lang;
    using Toybox.System as Sys;
    import Toybox.WatchUi;

    class testWFView extends WatchUi.WatchFace {
        var picback;

        function initialize() {
            WatchFace.initialize();
        }

        function onLayout(dc as Dc) as Void {
            setLayout(Rez.Layouts.WatchFace(dc));
           
        }

        function onShow() {
        }

        function onUpdate(dc) {
            dc.setColor(Gfx.COLOR_BLACK, Gfx.COLOR_BLACK);
            dc.clear();
           
            var picback = null;// FREE MEMORY    
            dc.setColor(Gfx.COLOR_WHITE, Gfx.COLOR_TRANSPARENT);
           
            picback = WatchUi.loadResource(Rez.Drawables.Picture);
            dc.drawBitmap(1, 42, picback);

            var clockTime = System.getClockTime();
            var timeString = Lang.format("$1$:$2$", [clockTime.hour, clockTime.min.format("%02d")]);
            var view = View.findDrawableById("TimeDisplay") as Text;
            view.setText(timeString);

            View.onUpdate(dc);
        }

        function onHide() as Void {
        }

        function onExitSleep() as Void {
        }

        function onEnterSleep() as Void {
        }

    }

    When you call View.onUpdate)_ that clears the screen first so anything you draw using the dc (drawBitmap) is lost.  Include the bitmap in your layout, or don't use a layout and use dc.DrawText() to draw the time over the bitmap and comment out View.onUpdate()

    Hey Jim,

    thanks - that was the part I didn'z understood. Ithought the view.onupdate would be essential to update the screen to see new figures ... but now it see it also works without.
