• Why Firefox is made of fonts while stairs and blocks, w/no anti-aliasing?

  FF 29.01 under Windows 7. You can see the image below the link to compare how browsers should make the fonts and how my browser actually renders the police. It is not a question of magnification. I have already installed the Anti-Aliasing Tuner extension. I added the layout.paint_rects_separately boolean as well.

  This only applies to Firefox? If yes you switch to another font in Firefox settings?

• Example of signals with a filter anti-aliasing

  I use PCI-6259 6221 PCI and USB 6221 cards in different configurations. As I understand it, is that the anti-aliasing filter on all of these cards is fixed to pass to the frequencies of 1 MHz. If I'm a signal from a RG58U BNC cable that is supposed to contain higher frequency of 1 kHz sampling, but there is noise of high frequency present there. A sampling of the signal to 2 kHz would be enough to acquire the signal correctly, or these high frequencies would affect the components of low frequency on sampling?

  I read about too much sampling that allows you to use digital filters (I'm guessing that software filter can be used) If you sample the data at a higher rate. You should always use the anti-aliasing filter, but the required parameters are more relaxed. Would this work in my case? The anti-aliasing filter on my cards has a very high bandwidth, so I don't know how much I need to do to acquire the signal correctly oversampling. Is there an equation?

  Also, if the analog inputs for data acquisition cards are generated by a filter (for example when recording ECG or EEG) which allows you to specify a bandwidth frequency, I still need a filter anti-aliasing? Would be the distance between the amplifier and the DAQ card much a difference when it comes to the generation of noise on the cable?

  In general, I try just to see if my current collection method at the rate of Nyquish with the maps I have is good or not. I just save the data without even using any digital filtering (software).

  That's right - if you go down to 10kS/s then the temporal resolution and minimum pulse detection would 100us.  If it is a just sampling rate or not depends on your requirements for the accuracy of timing and jitter.  In other words, if it's OK that your pulse Detection could could delay until 100us then a 10kS/s sampling frequency should be OK.

• Filter low pass analog (anti-aliasing filter) external to the NI USB 6251 housing

  Hello everyone!

  -I m trying to acquire an analog signal of tension (high frequency content) using a connected to an edge NI USB-6251 BNC-2110. I learned in this Labview Forum that NI USB-6251 has no analog low-pass filter programmable (or anti-aliasing filter), so that I can't help but jitter when scanning my signals. For my application, the cutoff frequency of the analog low-pass filter must be equal to 100 kHz or MORE (maximum of 500 kHz). A possible solution to solve my problem, would be to work with an external analog low-pass filter before you scan the voltage signal. Based on this I'd like to know:

  (1) national Instruments develops analog external filters? I need a filter which also has one output, analog, so that I could send also the low-pass analog filter filtered signal to my NI USB-6251 box to scan correctly it!

  (2) what model of external low pass filter would be compatible with the NI USB-6251 housing?

  Any help would be much appreciated!

  Best regards!

  Hello

  all high resolution of the M series (628 x) cards are equipped with a filter low pass which can be enabled or disabled programmatically. For the anti-aliasing filter feature, examine the boards of National Instruments DSA (dynamic signals Acquisition) acoustic and vibration measurement
  currently the NOR 9221, 9225, 9227, 9229, 9233, 9234, 9235, 9236, 9239 and 9237 C Series modules feature anti-aliasing filters. These modules are intended for the high accuracy measures for which anti-aliasing filters are a necessity.

• cRIO thanks the Module NI 9237 bridge in the Interface of scanning and Anti-Aliasing

  Hello

  I have questions about the use of a Module NI 9237 bridge with CRIO and its use in Scan Interface mode. The manual speaks the data rate of the module, and a (n) parameter that can be set to adjust (to a minimum of 1613 Hz) which in turn puts across the module built in anti-aliasing filters. It seems (but not explicitly stated) that this data rate setting is available FPGA programming mode.

  Our application is currently running in mode Scan Interface, so my question is what is 'throughput' module (and therefore anti-aliasing filters) mode Scan Interface? And, if we have the analysis period the value 10msec (100 Hz), y at - it no filtering of the anti-aliasiing of software provided automatically by scanning interface itself related to the period of scanning? Or all the anti-aliasing extra something that we must build within ourselves? I looked at the example provided with Scan Interface and there is nothing more.

  I don't understand about anti-aliasing, just need to clarify what is happening for this specific module mode Scan Interface.

  Thank you

  Andy

  Hi Andy,.

  I had to have a quick sleep on this night to get my facts right, hope that the delay was too long!

  The minimum data listed in the 1613 samples/s are due to a forumla that uses the internal time base that is fairly well explained on page 20 of the Manual. The sweep period did not affect the rate of data, or to activate the anti-aliasing filter. My previous post was wrong in that sense, apologies!

  This page helps explain mode of scanning pretty well too, but the best way to explain it is that even if the frequency of the module can be attached to 1613 samples/s or higher, the compactRIO will collect only 1,000 of these samples a second, or in your case if you are using a rate of 10ms loop, 100 of these samples of 1613. The anti-aliasing cut will be based on 1613 x 0.45 as you said and so will be 725Hz (not based on the rate of loop as I mentioned incorrectly)

  In this case with these modules it is probably a good idea not to use a period of scanning slower than 1 msec for the reason you said - if you're worried about oversampling you can always you decimate readings in the software afterwards to take each readings from 1 to 10 (this page explains how do with an eerily similar situation!)

• Anti-Aliasing feature in graph does not always, but inexplicably...

  I noticed a strange bug of Aliasing in the graphical indicator in my labview 2014

  I have attached a file that has two supposedly identical graphics but on my PC (windows 7, i-3 dual core, 8 GB Ram) charts two different display modes.

  The one labeled "aliasing problem" is jagged when anti-aliasing is turned on and when is broken. The other table behaves as I expect and I'm used to.

  (1) - does anyone see this difference as I do?

  (2) can someone explain the reason for this phenomenon?

  much obliged for any comment

  Thank you

  I see the same thing:

  

  There seems to be a bug specifically with the graph of scan (with the line). Power off the line, updates work fine. Also, turning aliasing seems then redraw the map with the correct folding (you can see that at Midway through the data on the first plot). You could try periodically calling the method "Force redraw' to see if that makes aliasing to update. It seems also set when you stop the VI.

  Weird bug since it is only on one of the graphics.

  (Also... What is with all the local variables and signalling of the value? (And the weird to leave timeout?)

• Full Screen anti-aliasing

  Well, today I have a question about disabling Full Screen anti-aliasing.  I installed Windows 7 on my Windows Vista OS in October when Windows 7 is released in stores.  I had a few games installed on my PC before upgrade me to Windows 7, but since I tried to install any game on my PC now that it works on Windows 7, the game will not play either or he advises me to disable the Full Screen anti-aliasing to play the games that I install.  The thing is, I don't know where to go to turn off Full Screen anti-aliasing.  I hope that it is in fact the resolution to resolve this issue.  Otherwise I won't be able to play the games that I like on my PC. Help me with this problem please.

• anti-aliasing using the 9233

  
  

  Hi Jeff,

  The first thing that you should start with is a guide to the delta sigma converter:

  It is the ADC that is used on the 9233. The delta sigma converter has a built-in inherent anti-aliasing filter. If you look at the dynamic features section of 9233 operating manual it will show you some of the features of this filter. The filter is a digital and the bandwidth and the stopband are calculated according to the sampling rate, you specify the 9233. If you give a sampling frequency of 50 kHz,-3 dB attenuation point bandwidth will be 50 k * 0.45 = 22.5 kHz. If all the components below 22.5 kHz will be kept completely and everything above that will be alleviated. This ensures that you will get no aliasing.

  If you apply a 20 kHz filter after that you'll still good data because the threshold for the anti-aliasing filter is greater than the maximum sampling frequency (50 kHz).

  Please let me know if this clarifies this question a little better.

• Windows 8 and anti-aliasing of fonts

  Hello!

  This is my first post in the Microsoft community.
  I'm a big fan of this company, and that I usually use their products in my studies, work, mail... etc.
  I've used Windows since XP, and I'm very happy with the last windows8.
  Windows 8 is much more fluid and more "BOLD", I love it!
  There's only one small problem, but it's really important me: font smoothing.
  I started using Ubuntu lately in my brother's laptop, and I was completely impressed by the display of fonts on it.
  It seems bigger, more professional and more :-)
  The police is 'acceptable' on windows only when it is greater than 50px.
  I see an evolution on this way on IE for ie9, but it certainly not the same as Ubuntu
  Can they take this thinking in mind when working with blue windows, or they will ignore it and continue with the fonts as 15years ago...

  Hello!

  I would like to offer a way to adjust your font smoothing.  To account for many types of LCD monitors and different types of pixels, Windows has adjustments to the police of smoothing method it uses.  It is possible that an optimal method of inferiority is currently used.  Here is how to adjust it:
  1. Open your startup screen and type the word "clear" (search results appear when you start typing).
  2. Select the category of settings on the right, then click on the result of research called "adjust ClearType text' to start the ClearType text.
  3. Click next in the wizard and then step through the calibration.  At each stage, you will be asked to click on the text that is best for you.  This will allow Windows to use better anti-aliasing of fonts for your system and your preference.

• JavaFX 8: how to make better anti-aliasing?

  Is it possible to determine the best antialiasing with JavaFX 8? I'm creating an application that requires controls rotation and they look pretty bad, you can see a serrated line even with smooth turned on. I also tried to adjust the default value of DISABLED SceneAntialiasing to BALANCED, but I guess it's just for 3D scenes and nothing helped. All recommendations on how I can improve this?

  Thank you.

  The smooth property is any hint how JavaFX should apply to a filtering algorithm internal to generate the imageview pixels when you have values of fitToWidth/fitToHeight for your ImageView. that is, it is unrelated to anti-aliasing.

  JavaFX does not provide parameters to configure anti-aliasing on a per node basis, on a basis of scene/subpicture.

  By default when you create a scene, JavaFX sets anti-aliasing to false for the scene.

  If you specify aliasing as SceneAntialiasing.BALANCED (rather than the default SceneAntialiasing.BALANCED), then your image in rotation will have images smooth (at least it worked for me on a Macbook Air + Java8u20 2012).

  Here is a small test program that you can try.

          );
          Node node = imageView;
  //        Node node = rectangle;
  
          node.relocate(M - 0.5, M - 0.5);
          node.setRotate(R);
  
          Group root = new Group(node);
  //        Scene scene = new Scene(root, W + M*2, H + M*2, false, SceneAntialiasing.BALANCED);
          Scene scene = new Scene(root, W + M*2, H + M*2);
          System.out.println(scene.getAntiAliasing());

• Is there a way to remove anti-aliasing on objects in PS?

  Without going into too much boring detail, I'm working on the art files created by other people. There are often dozens of smart objects (vector) that have been placed with active anti-aliasing, resulting in the rounded edges, that everyone loves so much. Fuzzy or crisp edges have no impact on the quality of the final product, but I can't get the artists to stop using it. The problem is that I need to make accurate selections of art as quickly as possible. Ideally with the magic wand. Is there a way to remove this effect, is looks like it would be simple enough to have a checkbox in the Properties window.
