Fit the Waveform LAF inside an ellipse

[Mighty23]

I would like to fit the shape of the waveform with the drawn ellipse, can anyone help me with my trigonometry homework?

// WAVEFORM LAF - Global LAF for waveforms
const LAF = Engine.createGlobalScriptLookAndFeel();

// Current Playback Position
LAF.registerFunction("drawThumbnailRuler", function(g, obj)
{
    g.setColour(0x60FFFFFF);
    var x = obj.xPosition;
    g.drawLine(x, x, 0, obj.area[3], 2.0);
});

LAF.registerFunction("drawThumbnailRange", function(g, obj)
{
    var a = obj.area;
    g.setColour(Colours.antiquewhite);
    // Draw an ellipse instead of a rounded rectangle
    g.drawEllipse([a[0] + 2, a[1] + 1, a[2] - 3, a[3] - 2], 2);
});

LAF.registerFunction("drawThumbnailText", function(g, obj)
{
    g.setColour(Colours.white);
    g.setFont("Oxygen", 12.0);
    g.drawAlignedText(obj.text, [310, 5, 70, 15], "right");
});

LAF.registerFunction("drawThumbnailPath", function(g, obj)
{
    var a = obj.area;
    g.setGradientFill([0x80762EFF, a[0], a[1], 0xFF2EFFE9, a[2], a[3]]);
    g.fillPath(obj.path, obj.area);
});

@Mighty23 Just made that post https://forum.hise.audio/topic/10292/paint-routine-rounded-image/4
That should put you on the track

@ustk Thanks for pointing me in the right direction; I'll do some testing.
