• extract a part of a picture to manipulate

  I tried to extract a part of a picture so that I can work on only a part of it.

  First of all, I import an image and use the tools KING to get the global rectangle.  Then I try to use the global rectangle to extract the part of the image that I want to work on.  That seems to work, except when I move the Courvite back on the original image, the original image "becomes" the extracted image... I tried to copy the original image before working, but the same thing seems to happen... any thoughts.

  This is because you have connected your destination "img" imaq extract.vi to a new imaq create. Create one, give it a different name. It will work.

• Can someone tell me how to extract a part of a digital waveform?

  I am trying to extract a part of 2 analog waves (using the http://zone.ni.com/devzone/cda/epd/p/id/4149 for example) analog signals is synchronized with a digital waveform.  I need to extract the same portion of a digital waveform.  Can someone tell me how to add the digital extractor in the example above?

  Hello

  Here's your extractor example slightly modified in order to add the digital data extraction.

  The principle is exactly the same, the tricky part is how to get digital data which is different from analog data.

  You can also add nodes property to identify the value read on the analog graph sliders on the digital chart.

  Kind regards

• How can I extract a part of a signal inside a loop control and simulation?

  I would like to extract the part of my signal between 0 and 3 seconds. I tried to use the extract of Portion of Signal VI Express, but it does not work. I'm setting the length to the offset 0 and 3 seconds. However, nothing is displayed in the output. I used this before VI successfully, but it wasn't in a loop control and simulation. Is there something special I need to do to make this work properly in this case?

• Extract a part of SelectedItem.data of ComboBox

  Hello!

  I only use AS2.

  A ComboBox is filled with elements all built on the same pattern:

  Each element contains:

  1 - name of the location (which can contain hyphens, spaces and apostrophes)

  2 - details (always indicated in parentheses)

  The user selects an item that will be sent to research purposes via PHP to query a MySQL database.

  The variable to send should only be the name of the place , because the location of my MySQL Table column contains the names of place without details.

  How can I extract only the name of the place?

  Thank you very much in advance for your help!

  Best regards.

  You can use...

  dataToSend = String (yourCBName.selectedItem.data) .split ("(") [0]; ")

  where 'yourCBName' is replaced by any name you assign to the combobox

  This line will split the data line in two parts where begins the parentheses and point to the first part of it.

  We know not if you use the appearance selectedItem.label of the combobox, that could help.  What you might consider doing is to have just the data part of the combobox control have the data you want to send, and use of the part of the label to display the entire bit of text you show... or the reverse of the where the label is just the part of name and that is what you send.

• Extract a part of a large MP4 in a swf

  I would like to create a swf (about 2 minutes) from a file (12 minutes) larger MP4. I can do using other software, such as Roxio Videowave, to extract the desired part and create a new shorter than Flash Pro MP4 can handle. My question is whether it is possible or even practical, to make video extraction using just Flash Pro. It would be desirable to do so because the step of additional software seems to reduce the quality of output.

• Y at - it an easy way to do it (this part of skin of object)

  Lets say I want to draw a look almost close, it would be great if I could do with an ellipsis (for eye) and a circle (for the student)

  The problem is that the student (who will be at the center of the eye) go beyond the border of the eye above and below.

  I was wondering if there is a way to get the point of intersection of 2 objects, so I want to show only the intercection of the pupil in the eye

  Select both and press Ctrl + 7, (mostly down) the student is going to get cut to the eye (top of page)

• Possible to extract a part of code HTML of WebView and exposes to QML?

  Spending a few hours to research this, but not really sure.

  My application has a lyrics Viewer, it opens the page with a WebView then uses evaluateJavaScript to strip all normal visible header and the actual words, everything works great and leaves me with just the text words.

  I would like to take that text and somehow move it to QML so I can strip things html and ending up with a gross QString with the text of the words and finally display it with a tag, but not really sure how.

       webView.evaluateJavaScript(
                           "var content = document.getElementById('mw-content-text');" +
                           "while (document.head.firstChild) { document.head.removeChild(document.head.firstChild); }" +
                           "while (document.body.firstChild) { document.body.removeChild(document.body.firstChild); }" +
                           "var header = document.createElement('h1');" +
                           "header.style.color = ('white');"+
                           "header.innerHTML = '" +  lyricsDataArtist+ " " +  lyricsDataSong + " Lyrics';" +
                           "document.body.appendChild(header);" +
                           "var lyrics = content.getElementsByClassName('lyricbox')[0];" +
                           "lyrics.removeChild(lyrics.firstChild);" +
                           "document.body.appendChild(lyrics);"+
                           "lyrics.style.color = ('white');"+
                           "document.body.style.background = ('black');"
                           );
  

  Any ideas appriciated.

  Thank you

  I suspect you can do what you need by calling navigator.cascades.postMessage () of your injected JavaScript and catch with the WebView::messageReceived signal. I use this mechanism in my application support to get stuff to the pages loaded in my C++ code, but it also works well with QML.

• Extract parts of value date Selected DateField

  Hi people,

  I would like to extract the part of the year of the value selected from my datefiedl.

  For example, I would get 2010 from: 23/12/2010

  And check if the extracted year is less than the current year.

  How can I do in LiveCycle (JavaScript is better)?

  Thank you

  Yair

  var Input = Num2Date (Date2Num ($.formattedValue, JJ.)) (("" MM. YYYY '), 'YYYY')

  Var Num2Date = (date (), "YYYY")

  If (input only those) then

  xfa.host.messageBox ("bad year")

• [Q] can Vision track multiple objects in the same area - objects that might cross?

  Hello

  Sorry for this long title, but this is my question.

  Can Vision track multiple objects in the same area - objects that could cross?

  Because I'm able to do, extraction of XY, but it seems that "IMAQ County objects ' don't follow framework after but framework opposed, but extract the coordinates XY always in the same way, as for example from top and whenever he sees an object, it retrieves the XY, but if the objects pass through (then it will extract XY without worrying that the objects was the earlier but just based on"scan from top to bottom").

  That's why I open this topic in the forum of Vision no part: http://forums.ni.com/t5/LabVIEW/Sort-XY-by-closest/td-p/2440428

  Thank you

  Sébastien

  Thank you for your response.

  My problem is that we work with very small insects and the shape/color is the same for all.

  Then the solution is: Let's wait for "IMAQ County objects 3 ' then .

  Thank you

• method accewwing from another thread causes some 'bad object type' error with c# VS2008

  I'm snapping a picture to a main Viewer, draw a rectangle around an alignment and extract the part of the image to a different viewer for further processing. I tried everthing and all was good until I started to build a Wizard for the operator through the process of the market and do things automatically. If I have access to this method of the mainform thread, everything works fine. If I access it from the thread of substantive assistants work it fails and gives the error "you have provided the wrong type of object to the function. Spend a CWIMAQRectangle instead. »

  public int ExtractToGP1()

  {

  CWIMAQLearnPatternOptions LearnOptions = new CWIMAQLearnPatternOptions();
  CWIMAQRectangle RoiRectangle = new CWIMAQRectangle();

  int Count, result;

  Extract the region corresponding to the model selected in the main Viewer

  Result = axCWMachineVision1.GetSelectedRectangleFromViewer (axCWIMAQViewer1.GetCWIMAQViewer (), RoiRectangle, true, 1); //<--error>

  Result = axCWIMAQVision1.Extract2 (axCWIMAQViewer1.Image, axCWIMAQViewer5.Image, RoiRectangle, 0, 0);

  I tried to use:

  axCWMachineVision1.Invoke (delegate (MethodInvoker)

  {Result = axCWMachineVision1.GetSelectedRectangleFromViewer (axCWIMAQViewer1.GetCWIMAQViewer (), RoiRectangle, true, 1) ;})} ;

  axCWMachineVision1.Invoke (delegate (MethodInvoker)

  {Result = axCWIMAQVision1.Extract2 (axCWIMAQViewer1.Image, axCWIMAQViewer5.Image, RoiRectangle, 0, 0) ;})} ;

  but this only works if the method is called by the main thread.

  Resolved to myself. Not really a problem of OR.

  I moved

  CWIMAQLearnPatternOptions LearnOptions = new CWIMAQLearnPatternOptions();

  CWIMAQRectangle RoiRectangle = new CWIMAQRectangle();

  for my vision instead of having it in the method class, which is in the mainform class

  Then use Vision.RoiRectangle vs RoiRectangle and Vision.LearnOptions vs LearnOptions.

• Get the name of the object raising the event

  If I have a change event for a checkbox that is declared like this:

  topmostSubform.Page2.Competitions_CB.Checkbox::change - (JavaScript, client)

  How can I get the path of the object in a variable to process and extract the part "Competitions_CB"? Same route to the top of the tree of objects would be nice, but I can't seem to find the property that returns the object names.

  I went through all properties that seemed likely, xfa.event, events and this, but nothing seems to be what I'm after.

  Hello

  With the help of 'this.somExpression' will return a string of the trajectory of the entire article;

  XFA [0] form [0] .topmostSubform [0]. Page 2 [0]. Competitions_CB [0]. Box [0]

  You can also use 'xfa.context.somExpression' to return to the same thing, using xfa.context is very convenient when the code is in a script object and called many events of the object.

  In addition, "parent.name" would return the "Competitions_CB" part, so parent.somExpression would return

  XFA [0] form [0] .topmostSubform [0]. Page 2 [0]. Competitions_CB [0]

  Concerning
