The user image display

• Blocks the execution of the user Image Acquisition interface

  I am currently trying to create a user interface that displays images from a camera attached to a microscope with a mobile table.  The user is able to interact with the images and can click on them, which causes the table to move to a new location.  Acquisition is made by calling a DLL, the DLL grey flycapture point camera, using a call library function node.

  When I acquire images at 15 frames per second, it has no problem with user input.  However, when I drop the acquisition at 2 frames / second (necessary if you need to have the exposure time), labview seems to take a break from the user interface while the image acquisition is underway.  Interaction of the UI seems possible in the holes between the image acquisitions.

  I'm sure that this is happening because there is a kind of blocking going on here.  The program is waiting for the new image to be returned and will not not something else happen while he waits.  I have image acquisition running in a separate, called function from a higher level, VI, which puts the image data in a global variable (I know I know... global variables).  When I need to display the image, I read of the global variable and display it on my form of user interface.

  I think I need to run things in separate threads to avoid the problems that I have because I have a dependency that is the cause of blocking.  I'm looking for any suggestions on how I can the architect this.  I have thought about using a VI server to launch the acquisition of the camera and will try to implement this, but I wonder if there is another method that I'm missing here.

  Any suggestions would be greatly appreciated!  I use LabVIEW 8.6 on a Windows 7 machine indeed.  I do not use LabVIEW image acquisition module.

  Thank you

  Hey Gerry,.

  It's Paul in Ministry here at National Instruments engineering applications. What Paul was referring to a call library function node configuration properties. If you right-click on the node library function call you can click on configure and you should see a window that looks like the image below.

  

  As you can see, you have the option to select run this library in the UI thread or any thread. This is important because there is only a single user interface thread. Therefore, deadlocks can occur when the code is written in parallel, but operations are both occurring in the UI thread. What results is a part of the code has to wait that the other part at the end and so the lock upwards in the user interface. The reason why the call library function node is set to run in the default UI thread is now, because only the security thread functions can be performed in any thread. So before you change this configuration it is strongly recommended that you check that the functions you call are thread-safe. You can also check which configuration, the node library function call is in the color of the node itself. If it is an orange color which means that it is set to run in the UI thread. If it is a pale yellow color, it is set to run in any thread. Let me know if you have any other questions!

• The initial image display problem

  I am a new Adobe product photo and Lightroom so forgive me if this is a noob question.   Also, I did a just try to find a solution before posting, but I may not know the correct nomenclature of Adobe to search for, so that is:

  When I import a library of LR3, which was shot with my Nikon D200, dynamic look thumbs.  As soon as I click a thumb Gets a tinge of greening and seems more muddy.  In addition, as the enlarged image will load on my second screen, for a while, it is great then all of a sudden LR3 applies which I suppose are parameters of the camera for the photo and the greenish and muddyness is back.

  I know my D200 present some problem of unexplained color (even with full reset), but how can I LR3 completely ignore the camera settings and show me this image brighter and more vibrant, I see a moment?

  I shoot Raw + JPG small.

  Thank you

  Sunil

  All the profiles you see listed ARE for the D200.  Lightroom displays only the profiles for any camera took the picture.  If you try to turn on a JPEG profiles, all you will see listed is "incorporated", there is no profile for JPEG images.  The camera settings are applied when the JPEG image is recorded by the camera.  Cameras Nikon seems to have a list of 'standard' profiles for their various digital SLR cameras.  I have worked with images of a number of different models, and the list of profiles is the same for each of them.  D2x profiles are for your camera.  So don't expect to see your model listed.  Which has already been supported.

  Hi Habib.

  For documentation, you can read the developer's guide. You will get all information :D

  And fallow the code below to change password I tried an example for you, hope this helps you...

  JPs JpsContextFactory = JpsContextFactory.getContextFactory ();
  JpsContext jpsContext = jps.getContext ();
  IdentityStoreService storeService = (IdentityStoreService.class) jpsContext.getServiceInstance;
  IdentityStore is = storeService.getIdmStore ();
  UserManager mn = is.getUserManager ();
  Boolean flag = mn.isModifyUserSupported ();
  String userName = "[email protected]";
  User user = (User) is.searchUser (emailId);
  System.out.println ("User details:"+user.getUserProfile().getUserName()); ")
  UserProfile userprofile = user.getUserProfile ();
  Char [] oldp is oldPassword.getValue (m:System.NET.SocketAddress.ToString () .toCharArray ());.
  Char [] newp is newPassword.getValue (m:System.NET.SocketAddress.ToString () .toCharArray ());.
  If (newPassword.GetValue (). ToString(). Equals (confirmPassword.GetValue (). ToString()))
  {
  If (! newPassword.GetValue ().) ToString(). Equals (oldPassword.GetValue (). ToString()))

• How to display all the other images in the image indicator

  Hi all

  I use IMAQ for capture and record high freq and images high resolution. I have an indicator of image directly from 'Image Grab acquire'. Thus, the indicator image displays images at very high frequency too. To display frames, but not necessarily all alone (enough so that the operator can see what's happening). So, I wonder how I can view, say all the other images (for example all the odd/even number of images), or jump on two and show the third?

  Any help will be appreciated!

  Thank you!

  Wenlong

  Here are some general observations.

  • Image acquisition is "a horse of a different color" - in contrast to many other I/o devices, the memory containing the data (here called the "buffer") is handled by the driver and is not directly available for LabVIEW.
  • I'm guessing that you are using hardware OR video, because you use the IMAQ functions (I used only IMAQdx).  Is this true?  What camera do you use?
  • The (probably) "Awakenings" IMAQ extraction buffer herself to the camera (I say 'probably' because I don't know the hardware you use).  This means that While the loop containing it will work at the rate of the camera images (so you can easily calculate the frame rate, as your example code).

  This looks like a routine NI Demo, so I think that you don't have much experience with the treatment of Vision.  If you have a lot of other LabVIEW experience, you should be able to make the leap to the vision, once you have the idea of the functioning of the buffers.  Unfortunately, there isn't much in the way of tutorials and white papers on Vision than on other subjects of LabVIEW.

  Yes to your question - how to view every Nth frame.  This is the loop key (which arises directly from your code):

  

  As menioned above, this routine is 'clocked' by the function of extraction buffer.  What you do to display each image is th is to place control of the Image inside something like a Case statement that "triggers" each nth time.

  Here is a version of 'Nth' of the loop above (details omitted)-

  

  We always roll the filling of each buffer with a frame loop.  But we then use the whole function divide to select the nth image (those who have a remainder of 0 when i is divided by n-th) and of the 'image' line (it does not really an image) for 'Image' control, with the other case being "Default" (for all the other Valentine go) and nothing inside.  Thus each nth time in this loop, the output of the extraction buffer is the wire to an Image (and displayed), the other N-1 times the thread is going nowhere.

• Display multiple lines of data collection defined by the user in an e-mail message

  I created a collection defined by the user that displays several lines of data. I created a custom rule and have linked this collection set by the user to this rule and configure an e-mail action. Variable Seveity, I have defined it in the rule to contain the column values. But it will only contain the first line of data. How can I display multiple lines of data in the alarm itself as well as the e-mail? Any help is appreciated.

• Image display the user selected using FileReference

  I use FileReference to allow users to choose an image of their hard drive. Once the user selects the image I would like the image to display in the .swf before they download it.
  
  I tried this:

  ....
  var bmpData:BitmapData = BitmapData (fileRef);
  var bm = new Bitmap (bmpData, "auto");
  screenHolder.addChild (WB);
  
  and this:

  var request: URLRequest = new URLRequest (fileRef);
  Loader.Load (request);
  screenHolder.addChild (loader);
  
  but these don't work.
  
  does anyone have any suggestions? What I do is it possible? Or do I have to use a server?

• Display image based on the value of the variable of the choice by the user

  Hi all, I hope someone can help with what I think is a simple request. Ive only been using Captivate 7 for a few days and still feeling my way around things.

  I installed a question multiple choice quiz that has 4 possible answers (correct 1: incorrect 3.)

  It works fine out of the box, and when a user presses the button send the response box appears showing if the user responded to this correctly or not.

  What I want to do, that is forward a bit, and if the user gets the answer wrong I would a small image of a check mark appears next to the correct answer.

  I have included my image on the stage, he gave an alpha of 0 to hide effectively.

  In interactions in advance, I created a variable called showImage with an initial value of 0

  What I am struggling with now is how to increase the value of the variable to 1 when a user selects a wrong answer and change the alpha of 0 to 100 for show the image illustrating the choice of the correct answer.

  I know that what I have described, is essentially what is happening at the end of the quiz, if a user has access to review their answers but I would like to be able to do as they progress through the questions.

  Thanks a lot for your help

  D

  Hi D,

  What you need to do is rather than make his alpha 0. It completely hide the scene until the user gives the correct answer.

  So, I want you.

  (1) insert a picture

  2) go to image and all properties panel up - untick 'Visible output.

  (3) open properties Quiz, select under Actions failure level 1/2/3

  (4) select 'Last attempt' as 'Show' and the image you you inserted

  This way the image will appear if the user selects an incorrect answer.

  I hope this helps.

  See you soon,.

• Individual images WVC80N FTP on an interval defined by the user to a remote server does

  Hello

  I'm shopping for a wireless webcam to provide periodic fixed images that are accessible via any web browser. I'm not interested in live streaming video, or what I must have remote users to directly access the camera.

  I currently own a Panasonic BL-C131A that performs the necessary function well. I set it up to send a simple jpeg image to a remote server every 60 seconds (assigning the same file name each time). My web site (http://www.creston-community.com/Public/Webcam.html) has a page that displays the uploaded image, i.e. the .jpg file, in the same interval. Of course, whenever the web page pulls the top of the file, it contains a more recent image this file contained on the previous cycle.

  I need a second camera, but Panasonic is expensive. I seems that maybe the WVC80N could be an alternative to a price much lower. However, I have reviewed the user for the WVC80N guide and the only mention of ftp of it lies in the section dealing with motion detection. Can someone tell me if the camera can do what I ask, independent of any movement detection settings? If Yes, can I specify jpeg as the file type, set a preferred file name that will be assigned to each image and set the frequency (interval) between ftp downloads?

  Thanks for any information anyone can provide. !

  The WVC80n doesn't have the specific feature you are looking for, not exactly.

  However, it can achieve the desired result in a different way.

  The willing WVC80n of a CGI interface that your web server could pull left to draw the image, instead of the camera by pressing the image.

  In other words, you can set a timer for one minute on the web server to retrieve a single image of the WVC80n jpeg and save it like that.
