How should I do to render fluids in a bar in a GUI?

I read about TextureAtlasSprite on this forum, but it was on 1.15.2.

 

I suppose to have to:

get the amount of fluid and I did it with FluidTank#getFluidAmount(),

get the still texture of fluid and I did it with Fluid#getAttributes()#getStill().

 

Now how can I do to render in the bar?

What version are you developing for?

1.14.4

I haven't tried doing what you are doing or something similar yet, but I would say probably take a look at the furnace, and see how it renders the progress bar. I know your thing isn't a progress bar, but it should give an idea about rending an image based on a % of completeness (or, fullness).

It Is almost useless for me because I know how to fill the bar based on a %.

I am trying to render each fluid in a bar

i.e. 

If It contains water, bar will be blue, if lava, will be red... 

Of course furnace doesn't do it.

This is what I would do.
