• What you're doing there with the getShoeImageSource function looks good to me.

    In terms of the different rendering, could it be that the default 'theme' is different on Bangle.js 1 and 2? 1 uses white on black, 2 uses black on white, but they are configurable.

    The layout library is a tricky one - it does use a lot more memory/time than just manually specifying sizes, but then it is a lot more flexible. I'd love to get the memory usage down, but it's hard as it does have to store the layout information for each UI element.

    Well, just measured and calling the getShoeImageSource takes 15ms

    >var d=Date();getShoeImageSource();d=Date().m­s-d.ms;
    =15.47241210937
    >var d=Date();getShoeImageSource();d=Date().m­s-d.ms;
    =15.65551757812
    

    writing to file and then drawing it from file vs from getShoeImageSource

    var s=require("Storage")
    s.write("yyshoeimage",getShoeImageSource­())
    >var d=Date();g.drawImage(s.read("yyshoeimage­"),20,20);d=Date().ms-d.ms;
    =12.05444335937
    >var d=Date();g.drawImage(getShoeImageSource(­),20,20);d=Date().ms-d.ms;
    =26.51977539062
    

    whether 15ms of CPU time is worth optimizing (for power, when e.g. redrawing watchface periodically) is of course debatable, if drawn every second it can make a difference.
