Yeah Bitman is awesome but I don't think it really helps with anti-aliased display of 2D primitives like lines and arc's

Just wondering, since we have some SVG afficianado's in the audience, if it is possible to use LV to dynamically creat SVG content and display within a .net container? I can see that it is possible to place a .net picture control on the front panel but I think SVG would be much more elegant. A little ranting here... I am a little frustrated that all LV programmers have for developing embedded custom 2D graphics is the very very very old 2D picture control. The rest of the world has marvelous tools like WPF, SVG or even GDI+. Yes, I know, as many have pointed out, that you can do anything with the 2D picture control and I think LV'ers get a kick out of how much they can force out of such primitive tools. Wow, how did you get the picture control to do that nice anti-aliased display with z-ordering of emulated alpha channel bitmaps? I think some people would be willing to pay for a nice 3rd party 2D graphics toolset.

I have been looking for a way to generate perfect antialiased circles that I can programmatically manipulate (position, radius, color). Seems like a simple enough goal but is not very easy to do unless you want to jump into the 3D picture control api and generate meshes for every anti-aliased primitive you want. Finally I found that the silver gauge control has some ultra cool antialiased circular decorations that can be used for this purpose. I am attaching an example to demonstrate. It would be really nice if the decoration palatte would get some native anti-aliased primitives and of course it would be extra nice if the picture control would also get anti-aliased as well. Actually I think the holy grail would be a 2D version of the 3D picture control. BTW, you can use the xy graph to draw antialiased circles but they always look a bit bumpy. Antialiased Circle.vi

Hi Vugie, I am also exploring various 3D engines for use in aircraft simulators. I thought at first to use the native 2D picture control with your BITMAN library (very nice!) but found that I would need native support for transparency and anti-aliasing. Do you have any examples of using LabVIEW with VTK? Thanks

I would like to be able to capture a controls image but have noticed that the Get Image method does not include mask data or any way to preserve transparency. Perhaps someone has found another way to do this?

and when you really really really think about it... free will is a somewhat convoluted concept.

Ok, here is what I have found... Anti-aliasing options need to be selected in the advanced settings of your computers graphics card. Once I enabled antialiasing (there are many different modes, see http://www.tomshardware.com/reviews/anti-aliasing-nvidia-geforce-amd-radeon,2868.html for a good tutorial) for all applications on my machine then my 3D picture control started drawing with anti-aliasing. You can configure anti-aliasing to be global for all app's or tailored to specific app's with the app determining if anti-aliasing is enabled or not. I think if you do this then the anti-aliasing enable property node in LV might start working. Thanks Vugie!

Maybe you guys are a little too hard on this fellow. Personally I enjoy unusual 'educational' threads like this. Actually some of my favorite threads ended up with someone getting kicked off the list

Interesting...could you post your code, I would like to see if I get anti aliased output on my machine. Thanks.

Has anyone ever seen this feature working? I am gearing up to start design on a aircraft EFIS emulator and would very much like to have features such as anti aliasing and transparency. Transparency works out of the box with 3D picture controls but anti aliasing is still a no-go...

Next Generation of User Interfaces... http://zone.ni.com/wv/app/doc/p/id/wv-3567 I really love LV so it is especially disheartening to see what we are missing...

I had a problem with a flickering numeric display and was able to fix it by placing caption text inside of the indicator. In my case it was a time display so the caption 's' to the right of the left justified numeric seemed fitting.

If I set the digital display in a text ring to hexadecimal I expect that I should be able to show the radix. The option is not available (I was wondering why) and the only way to sort of get it to look correct is to use the advanced format option and insert a 'x ' in the format string. The does not look correct since the normal radix display does not seem to use a normal font. Was wondering if anyone had any better ideas?

Great Idea - just kudoed it.

In 15 years I never used the matrix control before, nice! It does not unfortunately get the gap smaller than a classic array. Looks like we would need someone with access to the LV debugger to get down to a one pixel gap.

I am trying to create an array of numerics that are as close together as possible. A long time ago (maybe on info-labview) I seem to remember a discussion on this subject and a technique for doing this. But so far I cannot figure out what the trick was.

I was wondering if there were any tools that can take a project and compile hyperlinked HTML/Word/PDFdocuments of all of the vi's in a project including vi connector, vi documentation and organizes the vi's within the document to reflect the project organization. Thanks

For the uninitiated, it would be nice to repost that infamous NIWEEK video....

By golly that does work! Must be a Monday morning

Greetings All, I have a multicolumn listbox that has a user defined right click menu. I would like to be able to have the listbox selection highlite change automatically to the row that has been right clicked. I have tried everything that I can think of but cannot get this to work. Any suggestions greatly appreciated!

Would anyone venture to guess if the 'unlimited' desktop RTE includes Linux installations?

Yeah, that makes sense. But I seem to remember a very long time ago getting a quote from NI for a pack of 50 RTE's. I guess only old timers like me can remember such antiquated practices.

Is it true that the LabVIEW RTE has an unlimited license? Of course I know that some toolkits are exceptions but I seem to recall that at one time NI required at least one piece of their HW to allow unlimited use of the RTE on a target machine.

Thanks I will give that a try.

A very old DOS legacy system needs to be replaced and it uses the RS232 handshaking lines to drive a solenoid. I seem to remember that I used to have a vi that could set the DTR line directly but cannot find it. Anybody happen to have something like this in an old dusty toolbox?
