VU Meter image strip jumps on the latest frame

[orange]

@Lindon said in VU Meter image strip jumps on the latest frame:

@orange - hmm looks like it's maybe in your image itself:

Image is ok I've checked.

Can we give a lmit for the read value? let's say no reading above 2 dB?

[Lindon]

@orange well I removed any dependence on the volume and replaced it in your timer with the knob value. As you will see when you move the knob it applies a "virtual volume" - so you can better check your timer code....you will see when you use it your vu meter is jumping about all over... so either your image is off - or the code you are using in your timer is the problem.

@Lindon Issue is gone when I set the height and width to the original image sizes.

What about scaling the image? How can we scale the panel image down without using width and height? Because scaling down the image makes it a little sharper.

@orange good question -maybe some combination of panels inside panels? - I never do this "rescaling to get a sharper image" thing...I leave all the image processing to photoshop (or gimp in my case..)

[orange]

Wow! Setting "width": 151, to "width": 150.9, issue gone.

Since the strip is vertical, at first I thought that the issue was about the height value, but it was width. So weird...

[Lindon]

@orange - glad you got it sorted.

[Dan Korneff]

I encountered the same issue and ended up setting the index to Amount of Images - 1. That worked on my end. (basically discarding the last frame).

[Dan Korneff]

@orange Could this be globally related to the decimal issue I'm seeing in other things?

[orange]

@dustbro Yes it could be. This decimal sample delay issue right?

[Dan Korneff]

@orange yup

[DanH]

@orange Can I ask a noob question pls:

// the yOffset is index * heightOfFilmstrip
    	this.setImage("filmstrip", 0, index * 120.0);

What's is heightOfFilmstrip referring to?

heightOfFilmstrip value is the exact height value (in pixels) of the each frame in the image strip.

Below height value is for the final resized look.

Content.setPropertiesFromJSON(name, {
      "width": 151, 
      "height": 83,
      "opaque": true 
     
    });

[DanH]

@orange Oh right, I get it now, that's what confused me! Thanks :)
