How to add a background to a watchface

Hello,

I am trying to adapt my forerunner 945 watchface to the forerunner 965.

Before, I was doing this to add the background :

function initialize() {
    WatchFace.initialize();

    background = new WatchUi.Bitmap({
        :rezId=>Rez.Drawables.totoro,
        :locX=>0,
        :locY=>0
    });
}

function onUpdate(dc) {
    dc.clearClip();
    
    // Background
    background.draw(dc);
    background.setLocation(0, 0);
}

It was working fine withe the 945, but now, with the 965, it displays nothing...

Can you help me figure out why ?

Thank you

I guess you should switch the last 2 lines. It makes no sense to set the location after drawing it. But Probably that will also not fix the problem.

Thank you for the answer, but as you said , even if I change that, the image is not visible.

what about the other things you draw? Are they displayed?

Yes, they are. But they are not images.

Why are you setting the location twice?

Under initialize, something like:

image = WatchUi.loadResource(Rez.Drawables.myImage);

And onUpdate:

dc.drawBitmap (0,0,image);

How does totoro drawable look in the xml? Maybe the format that works on the 945 doesn't work on 965 (though hard to believe)

It looks like this :

<drawables>
    <bitmap id="LauncherIcon" filename="brothers-icon.png"/>
    <bitmap id="totoro" filename="../drawables/totoro_couleur.png"/>
</drawables>

Do you have any tutorial of a watchface that integrates an image in the background ?

0 flocsy🤠 16 days ago in reply to HACHIKO.AUD

I don't know if that would help if the same code works on one device but not on another.

BTW where do you have the problem? sim? real device? both?

Maybe it's somehow related to the difference between MIP and AMOLED display.

The problem is on the simulator and on a real device.

I think it has something to do with the AMOLED Display, because a few years ago I didn't have any problems migrating from forerunner 935 to 945. Or maybe it has something to do with the new version of the sdk...

It's too bad that garmin doesn't give any examples/tutorials.
