LV 2021 thick line decoration changed

[brentjustice]

The thick line changed in LabVIEW 2021.  More specifically, it looks like it is now anti-aliased with smooth edges.

While that is a nice feature, it breaks a bunch of my old UI things where I had expected the thick link to have no aliasing.

Ideally, this would be an optional property of the line decoration.

Thoughts?  This seems bad

Add this to your labview.ini and the good old sharp lines are back:

SmoothLineDrawing=False

I don't see any anti-aliasing, no matter what I set "SmoothLineDrawing" to.

It's for line decorations only (and the objects that include them). Other cosmetics seem to be unaffected.

I never get smoothing.  It always looks the same regardless of the state of SmoothLineDrawing.  It always looks like this:

Maybe it's a difference in what graphics cards or drivers you're using??? 🤔  For some strange reason, I see Paul working on an old Mac.  Probably a Lisa. 😅

I am old and crotchety, and do tend to hang on to old stuff as long as it works, but  I'm not that bad.

I've tried it on 2 different Windows 10 machines (one laptop, one rack-mount)

I just discovered this a few days ago:
The change seems to have happened between LV 2021 and LV2021 SP1.

What version are you using?

WOOT!  Thank you for the INI key

[brentjustice]

If I might ask, how did you figure this out?

I'm right there with you Paul.  My first PC was a Mac 512K with TWO floppy drives!  The Lisa was way too expensive, but I hear it was quite a powerful machine in its time.  Just like us.  😎

BTW, I tried the SmoothLineDrawing=False trick and it didn't work for me either.  I have a basic HP i5 Win10 PC but it does have a GTX1050 GPU so I expected it to work.

EDIT: Just saw the post about it happening in LV2021.  I'm still on 2019.
