Real Screen Width / Height on round watches

Hello, is it possible to get the real screen width on a y position or the real screen height on a x position on round watches?

You have to calculate it yourself (for semiround watches this will be an approximation ofc).

This is my (terrible) code:
```
(:round) private function getWidth(y)
{
    var radius = deviceWidth / 2;
  …
```

You have to calculate it yourself (for semiround watches this will be an approximation ofc).

This is my (terrible) code:

(:round) private function getWidth(y)
{
    var radius = deviceWidth / 2;
    //var angle = 2 * Math.toDegrees(Math.acos(1 - (y.toFloat() / radius))); // Angle = 2 * arccos(1 - height(y) / radius)
    //return (2 * radius * Math.sin(Math.toRadians(angle) / 2)).toNumber();
    return (2 * radius * Math.sin(Math.toRadians(2 * Math.toDegrees(Math.acos(1 - (y.toFloat() / radius)))) / 2)).toNumber();
}

(:semiround) private function getWidth(y)
{
    if (y == 0)
    {
        return 121; //biggest hack in the world
    }

    // not quite right
    var radius = deviceWidth / 2;
    //var angle = 2 * Math.toDegrees(Math.acos(1 - (y.toFloat() / radius))); // Angle = 2 * arccos(1 - height(y) / radius)
    //return (2 * radius * Math.sin(Math.toRadians(angle) / 2)).toNumber();
    return (2 * radius * Math.sin(Math.toRadians(2 * Math.toDegrees(Math.acos(1 - (y.toFloat() / radius)))) / 2)).toNumber();
}

Thanks, the calculation work.

But (:round) and (:semiround) does not work. I've get the error "Duplicate declaration of symbol 'getWidth' in class 'SingleBikeFieldView'."

(:round) and (:semiround) are excludes annotations,

you have to set them in your jungle file.

I try that, but it does not work:

    (:roundVersion) function getWidth(y) {
        var radius = deviceWidth / 2;
        return (2 * radius * Math.sin(Math.toRadians(2 * Math.toDegrees(Math.acos(1 - (y.toFloat() / radius)))) / 2)).toNumber();
    }
    (:regularVersion) function getWidth(y) {
        return deviceWidth;
    }

# Configure paths based on screen shape
round.resourcePath = $(base.resourcePath);resource-round
semiround.resourcePath = $(base.resourcePath);resource-semiround
rectangle.resourcePath = $(base.resourcePath);resource-rectangle

# Say that all products exclude declarations
# with the annotation :roundVersion
base.excludeAnnotations = roundVersion
# Now say that the round products exclude
# the regular version
round.excludeAnnotations = regularVersion

Where is my mistake?
