• Superposition of the images on the specified point

  Hello!

  I have 2 pictures with a lot of similarities. I want to layer them on a specified point or edge or a unique feature. Is it possible to choose a point (by hand or by an algorithm) and then find the corresponding (or similar) on the other image? and then superimpose the images according to the corresponding point? Algorithm of the overlay is made, now I need to find matches between the two pictures and then you cover them according to the similarity.

  Thank you!

  Hello

  I modified the labview example. Run it, input two images (left, right), then "load", select the edge KING (see image below) and "search". Then superimpose one image over another with transparent ('overlay'). The code is a bit messy, but you can clean for your project.

  

  You said that the superposition algorithm is done, could you please share it? Maybe your solution is more sophisticated and can help me with another project.

  I hope this helps you.

• Select from a drop-down list and the specified element values are displayed in the textfield

  I need for one to be able to select from a list drop-down and specified the item values appear in textfield.

  For example, if I select Amy

  If I select Bob

  If I select Jane

  Amy

  Bob

  Jane (I want to appear as shown in the list)

  I associated a value to each item in the drop-down list so that the choice is easy to compare and determine what initial (default) value to the value in the text field. In my drop down list change event, I have the following:

  var sNewSel = this.boundItem (xfa.event.newText);

  Switch (sNewSel)

  {

  case '1': / / Amy

  TextField1.rawValue = "Amy \n";

  break;

  Switch (sNewSel)

  {

  case '2': / / Bob

  TextField1.rawValue = "Bob \n";

  break;

  Of course that's not work one name shows at a time. Help, please!

  Thank you

  Don't know what the code is supposed to do, but basically, you want to add the name of the drop-down list the addition on the current value of the TextField? Why not use the dropdownlist display value directly? For example on the change event:

  if ( TextField1.rawValue == null )
      TextField1.rawValue = xfa.event.newText;
  else
      TextField1.rawValue += ( "\n" + xfa.event.newText );
  

• Video Start at the specified Point

  Hi, I'm hoping to learn how to make a video start playing at a specified point in the middle of the video rather than from the beginning. Not sure if this is something that can easily be done in Dreamweaver or if she's involved with the flash settings, but any help would be greatly appreciated. Thank you!

  1. use:

  Fl.video import. *;
  my_FLVPlybk.addEventListener (VideoEvent.COMPLETE, rewind);
  function rewind(eventObject:VideoEvent):void {}
  my_FLVPlybk.seek (52);
  my_FLVPlybk.play ();
  }

  2. unless you're streaming your video, you must use a video with keyframes (IE, cuepoints).   That is to say, use the addASCuePoint() method.

• Specify the end point for the digital using an output circular buffer

  When you use DAQmx and a NOR-DAQ for issuance of a digital signal using a circular buffer (buffer Renault). The program works and works, but when the 'DAQmx Stop Task.vi' function is called to end the task, he stops at the output buffering as soon as it is called and does not wait until the buffer pointer reaches the final value in the buffer. I would like that the program to wait until the buffer pointer is on the last value in the buffer, does anyone know how to specify this setting?

  If you need to stop on exactly the last sample output you will need a way to trigger the stop in the material.  The options available to you will depend on what hardware DAQ, you use, but here are some possibilities on the top of my head:

  1. set up a digital output redeclenchables task finished (not all hardware supports).  Set up a counter of output to issue a periodic trigger with the necessary synchronization signal such that the end result is a "continuous" digital output without interruption.  When you stop your loop, stop the task of counter - digital output ends his generation but the trigger signal will be removed and so it will not continue after that.

  2. If you have an unused extra digital output line, add it to your task.  This line should exit 0 all except the last sample.  Physically, this additional digital line in a wire line PFI and use it to trigger a meter output.  Have the output counter generate a single pulse of some long-term (long enough to ensure that the software can respond prematurely).  Use the output from the task of counter as a trigger of break for the task of digital output.  Do not start the task of the meter until you leave your loop.  Do not stop the task of digital output until you have detected in the software that the meter has been triggered.

  If you need to stop on approximately the last sample output, you could query the TotalSamplesPerChannelGenerated property after leaving your loop and only stop the task once it reaches a multiple of the size of your circular buffer.  This is no guarantee that it stops on the last sample (if you use a device on a bus with a latency higher as USB or Ethernet the non-determinisme would be worse).

• Error-200478 - specified operation cannot be performed when there is no channels in the task

  I write a task in NiDaqmx read 8 thermocouples 2 9222 or 4 thermocouples of a NI 9223 modules. Under Source of CCM I entered the channel and specified a type K thermocouple connected to a NI 9219. All modules are located in the same chassis of cDAQ9178.

  I get the above error.

  I add the CJC channel and he complains that I have double readings of the same channel in one of the tasks.

  The environment where it will be installed will vary widely affecting thus the constant CCM is not a viable option.

  Any help would be appreciated.

  Simple reason - we already possess the 9222 s of NOR and the NI 9223. I'll check the price NI9213 and see if the Group has the budget.

  I watched your program and compared it with mine. Tried to channel the CJC as Temperature_12 but all local channels are grayed out. BUT I moved Temperature_12 the command to the top you and Voila! He is available for selection. I put all 9222 s and 9223 channels at points to Temperature_12, and it saved without error.

  So I would say put the CJC channel as the first channel to read fixes the problem - it makes sense that the following channels need a reading to serve their CCM. Where this logic breaks down is if you consider that the 9222 and 9223 channels are simultaneous channels, but that's a topic for another post!

  For now, I thank very you much for your help.

• To access the 'specified values' through script

  When you specify (on the link tab) point values for a drop-down list field, how to access a script specified values - as opposed to access the string value?

  I use the example of WindJack script (part 1 of the list of programming) to feed a combo, but he needs to complete the initial drop string value - chains I have are a little long and unweildy and if they change I need to update the scripts, etc.. Be able to access the value of the drop-down list would make things much simpler.

  }
  

  Hi Jono,

  You can specify a value as the second parameter to the addItem method and then access this value using the method boundItem as when the values are entered in the designer.

  So in your case, you can load your values

  ReasonList.addItem (aReasons [i] m:System.NET.SocketAddress.ToString (), aReasons [i] m:System.NET.SocketAddress.ToString () .substring (0.2));

  In the click event (or both) then you can use;

  this.boundItem (xfa.event.change)

  to return the value which was adopted as the second parameter of the addItem.

  In your case, you can get out with the help of the .substring (0.2) to get the value, but an alternative would be to have an array of objects.

  'QHC returned the returned cheque': [{id: 1, text: "01: unclaimed at the address"}, {id: 2, text: "02: unknown address"}, {id: 3, text: "03: incomplete address"}, {id: 4, text: "04: No Such Post Office"}, {id: 5, text: "05: No Such address"}, {id: 6, text: "06: d."}, {id: 7, text: "07: moved, address unknown"}, {id: 8, text: "08: refused by the addressee"}, {id] [{: 9, text: ' 09: no reason given on the envelope "}, {id: 10, text:}" 10: returned twice to the same address "}, {id: 11, text:}" 11: additional information required - re - direct to the Department "}, {id: 12, text:}" 12: declined - duplicate payment "}]
  ,......

  Then, you might have;

  ReasonList.addItem (aReasons [i] .text, aReasons [i].id.toString ());

  ... Just in case they come with a 100th reason for not producing the cheque.

• The point value of graphic display WPF overview

  Hello

  Y at - it an easy way to display the value of a point (with formatting similar to a slider) flying over when the mouse point? I use the chart control WPF (MStudio 2013) with several plots represented graphic on an AxisDouble. (y-axis) and AxisPrecisionDateTime (x axis). Let me know if you need more information and thanks in advance.

  When a Cursor is set to align the data, it uses the FindNearestValue method to find the value of land near. When it is not set to align the data, he reports the value of the current screen with the ScreenToData method. The following code example shows how to use both to display the current value of the mouse on a chart using a ToolTip:

  private static readonly GraphQueryArgs query = new GraphQueryArgs(

        PlotsToSearch.Any, SearchDimensions.HorizontalAndVertical,

        SearchDirections.ForwardAndReverse, isInclusive: true );

  public MainWindow( ) {

        InitializeComponent( );

  graph.PlotAreaMouseMove += this.OnPlotAreaMouseMove;

        graph.PlotAreaMouseLeave += delegate { graph.ToolTip = null; };

        ToolTipService.SetInitialShowDelay( graph, 0 );

        ToolTipService.SetShowDuration( graph, int.MaxValue );

    }

  private void OnPlotAreaMouseMove( object sender, MouseEventArgs e ) {

        IPlot plot = graph.AllPlots[0];

        Point screenPosition = graph.GetPlotAreaPosition( e );

        IList pixelValue = graph.ScreenToData( plot, screenPosition );

        string tip = string.Format(

            "Absolute value at point {0} is {1}.",

            screenPosition, FormatValue( pixelValue ) );

        Point relativePosition = graph.ScreenToRelative( screenPosition );

  PlotValue nearestValue = graph.FindNearestValue( plot, relativePosition, query );

        if( nearestValue != null )

            tip += Environment.NewLine + string.Format(

                "Nearest value on {0} is {1}.",

                nearestValue.PlotObserver.Label,

                FormatValue( nearestValue.Value ) );

  graph.ToolTip = tip;

    }

  private static string FormatValue( IList values ) {

        return string.Join( ", ", values.Cast

    }

• How do the box values ring to have figures after the decimal point

  How do the box values ring to have figures after the decimal point

  Thanks in advance

  Control properties editor:

  Change the representation in the floating point data Type tab type, DBL will do.

  Then go to the Page of display Format and increment 'Numbers' to something greater than 1

  That toggles the column of values on the tab change the items to % .6f, or 6 digits of precision. Uncheck sequential following, values and you're there.

  If you think that's too restrictive, go back the display Format, then select if rating and you can type anything (but, the editor has a hissing fit, so you must load chains and property [] with a property node values programmatically)

• Write to digitall all ports (channels) with the decimal value

  Hello

  It is possible to write all digital channels with a value decimal for a device with 96 channels at the same time?

  I have a USB-6509 camera and I want to write each value of Pentecost bit 1 in the loop (for the first transfer I write 0,1,2,4,8,16, 32, 64 and 128) with the line "Dev3/port0 / line0:7", but if I want to write all ports at the same time, how to set the line and the "write.vi DAQmx?

  Thank you.

  You can configure the reading and writing in the ports of 8 bits with the 6509.  For example, you could write just 128 to "Dev3/port0.  If you want to write to all 12 ports, I recommend doing a task that is several channels on the 6509 module, each channel of the task being a port.  You can then use the channel Multiple, single sample of writing of your values.  Your values must be in a table of U8.
