Labview: "draw text" trouble

I'm trying out the "draw text" function(s) in the Picture functions subpallete, (Programming > Graphics > Picture Functions), and I found that it doesn't seem to respond to changes in [user specified font]. While it does respond to "Outline?", it doesn't respond to "Size", "Font Name", or "Bold?" (I haven't tested anything else yet).

Any suggestions?

Re: Labview: "draw text" trouble

The quickest way to try this out is simply to open the subVI that draws text. I chose Draw Text at Point.vi.

You can now enter params and see what affect they have right away, without having to write a test program.

Some of the things that can go wrong with the inputs are that the desired font isn't set to User-specified. Once it is, it uses the cluster below that describes the font. Some fonts do not support all of the options. Specifically, on Windows, they still ship a decent number of bitmap fonts. Those don't have arbitrary fonts, and will stay at a good size until you get to their next valid one. The bitmap fonts also may not support some of the other settings. If you use something like Arial, you should see all the features work. Use the Font ring to get other font names and try them out too.

If you see other things that don't work, be more specific and I'll look into it.

Thank you! I didn't notice the "desired font" control before.
