Rounding the sharpness of the display buffer graph

[orange]

I can get the graph below, but is there any chance we can round these sharp lines?

const var dp = Synth.getDisplayBufferSource("HardcodedMasterFX");
const var gr = dp.getDisplayBuffer(0);

gr.setRingBufferProperties({
"BufferLength": 65536,
"NumChannels": 1
});

const var Panel1 = Content.getComponent ("Panel1");
const var a = Panel1.getLocalBounds(0);
const var Cmpt = Engine.createTimerObject();

Cmpt.setTimerCallback(function()
{	
	Panel1.setPaintRoutine(function(g)
	{
		g.setColour (this.get("bgColour"));
		g.fillRect(a);
		g.setColour(this.get("itemColour"));
		var p = gr.createPath(a, [0,1,0,-1], 1.0);
		g.fillPath(p, a);
	});
});

Cmpt.startTimer(40);

For example like this:

@orange I've added a Path.roundCorners(var radius) some times ago

That's great. I tried below method but this doesn't work.

p1 = gr_peakreduct.createPath([a[0], a[1], a[2], a[3]], [0,1,0,-1], 1.0);

p1r = p1.roundCorners(10);
	
g.fillPath(p1r, a);

@orange Strange, that's the way I use it myself in many projects where it works...
And 10 seem to be large enough... Still, have you tried to increase it?

Can you put together a minimal snippet that shows the issue?

[ustk]

@orange You can also try to reduce the width for which you create the path. Using a (so a[2]) means that the path will be create with a 1 pixel granularity regarding the size of the panel. Reducing that value will lead in a smoother path, that you can then draw in the full panel's size so in definitive, reduce the granularity. Then roundCorners should work.

No luck, it gives "undefined parameter" error. This is the basic snippet.

@orange Oh wait... Can you please make a search in the Hise folder for this function roundCorners?

I might just have it locally and didn't make a pull-request...

[orange]

@ustk

I've already checked that. It shows up in the API list.

[ustk]

@orange Oh yes

The function does not return a new path but modifies the existing one. so just drop the p1r

And to reduce the number of points:

p1 = gr_peakreduct.createPath([a[0], a[1], a[2]*0.2, a[3]], [0,1,0,-1], true); // a[2]*20%

But although it works, it looks weird when I am testing it.
In my projects I tend to get the raw buffer and create the path from scratch myself instead of calling DisplayBuffer.createPath()

But since I use it essentially for spectrum curves, it might be an issue with the kind of signal you're using :man_shrugging:

[orange]

@ustk
I already modified the existent path, did you see the snippet?
I think this won’t work because of the same error.

[ustk]

@orange Yes I did, but I don't see where this path has been modified, the width is still the one from the panel with no reduction

p1 = gr_peakreduct.createPath([a[0], a[1], a[2], a[3]], [0,1,0,-1], 1.0);

[a[0], a[1], a[2], a[3]] this is equivalent to just write a
