Font Sizes in LabVIEW - Conversion Utility VI

[SimonH]

Someone recently asked me if there was a way to standardize LabVIEW font sizes relative to other Windows applications as altenbach describes in his idea exchange post

I did some digging and was able to write a VI to convert a point size into the equivalent LabVIEW size.

I'm posting here just in case anyone else is in need of this functionality. (Note that I haven't tested the backsaved LabVIEW 8.0 VI)

Something funny is still going on, I run the program to find out what size 72 point Arial should be.  Your code says 107 "point".

Create a label with 107 "point" Arial and it measures 0.75".  (72/96 = 0.75)

MS Word produces a 1.0" font with 72 pt Arial.

And the backsaved version was completely messed up and crashed my LV9 mercilessly.

Edit:  Found a non-standard display setting on my machine which must not have been sniffed down by this program.  It actually gets it much closer now.  I use a lot of graphic drawing programs so I really like to have 72pt = 1 in.

Darin,

Do you know which setting it was? If it's a common one we could track down where Windows keeps track of it and correct for it.

When I use 107 as my size in LabVIEW it lines up perfectly with 72 in WordPad (which I'm assuming renders the same as Word).

[Darin.K]

I'll see if I can track it down on that machine again.  I just turned off a few third-party tools and it snapped into place.

I may never use the code as you intended, but I always appreciate adding a few CLFN wrapped Windows functions to my collection.

I would appreciate you publishing that collection!

[David_Staab]

Darin, did you ever reproduce the problem?

[David_Staab]

Not working for me, either. I asked for 11pt Arial, but the recommended LV font (18 pt Arial) is one pixel taller than what WordPad shows at 100% zoom.

So this is useful and I appreciate it, but what about the reverse function?  Given a LabVIEW sized font text, what point size is that?  I can probably just run the posted VI for every point size I expect, and generate a list of LabVIEW font sizes, then reverse this in some look up, but if there is a more straight forward solution I'd appreciate it.

Just a note, please keep in mind that Windows offers a "font scaling" option that tends to mess up applications. Win10 is "supposed" to be a bit better, but this sort of functionality would almost certianly not work with the windows scaling feature.

Just for kicks, I looked it up and found an article suggesting Labview *does* take windows font scaling into consideration:

Thanks a lot，but it seems like your result do not suit me. Px for 蓝湖 is compared with pt for labview,but I can't find the regular to convert.

Hello SimonH，Hello Darin.k
I used the VI you wrote, but I got the same result as Darin.k

I checked that the zoom ratio on my machine is 100%, which should satisfy the default Windows of 96DPI per 1 inch, so I'm not sure what other display Settings I need to change to achieve the same results as yours
