• How can I make a label of wine bottle nonrectangular in 3D in Photoshop CS6?

  I got pretty proficient with Photoshop CS6 3D tools, but the mesh of the integrated wine bottle gives me a headache.

  I would like to make the label of a bottle of wine, some other rectangular. But when I use an opacity card to control the shape of the label (to make circular, for example), the bottle becomes as transparent. I have not found a way to make the transparent label areas while leaving the glass not affected. I tried black on the card as well as the transparent opacity (WARNING: no pixels). Whatever it is, the glass also disappears. In fact, if I'm trying to keep it smaller than its original size and same label rectangular - using black, transparent, or even cropping of the opacity for a smaller size card, it always affect the same area of the bottle glass (see picture). Glass is 100% opaque and has No card opacity.)

  
  

  This could be a bug CS6?

  Thanks in advance for any help.

  I think that I thought about it.

  1. With your material label layer selected, go to the properties panel. Under opacity, select 'New Texture'. Make the size of the file of the same size as your material of the main tag that surrounds the whole bottle.
  2. Create a black mask / white standard, the white area being your irregular shape.
  3. Save on the .psb. You should see only the areas you want to be opaque have now been hidden.

  I would also add that you must set the color of "Diffuse" your label to the same as the material of your bottle, as well as the correspondence the other properties (refraction, specular, etc.) so that the 'glass' corresponds to...

  Hope that helps!

• How to make a label (javafx) to display the current time dynamically?

  Hi all

  How to make a label (javafx) to display the current time dynamically?

  I have not found a Type of event related to the time in javafx API.

  Please give me some suggestions. Thank you!

  Sage

  There are lots of examples of JavaFX clocks available, for example https://gist.github.com/jewelsea/3388637 or http://blog.crisp.se/2012/08/09/perlundholm/an-analog-clock-in-javafx

  For a simple label displaying the time, the simplest thing is to create a Timeline with duration 1 second and the number of indefinite cycle, which triggers an event handler that updates the label:

  final Label clock = new Label();
  final DateFormat format = DateFormat.getInstance();
  final Timeline timeline = new Timeline(new KeyFrame(Duration.seconds(1), new EventHandler() {
       @Override
       public void handle(ActionEvent event) {
            final Calendar cal = Calendar.getInstance();
            clock.setText(format.format(cal.getTime());
       }
  });
  timeline.setCycleCount(Animation.INDEFINITE);
  timeline.play();
  

  (If you use Java 8, use the new time API, which is much more pleasant than calendar.)

• Make invisible movieclip

  Can someone give me a code example of how I do my movieclip called "cash1" invisible?

  I tried

  back1. Visible = false;

  and received the message in the compiler that this is not supported in AS3

  Yes, there are

  But you need to plan a little ahead of what you do. I don't use root or parent as a last resort infimous. On the one hand, this can confuse you if complete you the project and want to come back later. Probably you forgot how everything has been organized, and you will have spent too much time to understand what is the parent or root... they did not name.

  Finally, I always read that whenever possible do not use, it is regarded as bad, probably practice the reason why I said earlier, or even other.

  For example, you have a MovieClip and inside a MovieClip B. If you want to call a method B of a, and it is easy mvB.methodToCall (), right?

  But consider this. You want to remove B with a button located inside B. You can't, because the compiler will tell you that the child must be removed from the parent company, i.e., B, to remove of a.

  Two options: If you remove with a call to parent, or you can make a reminder of the function of wil.

  This last option is what I always do, without any problems at all. Basically, when you instantiate B, one of the arguments is a method name, which exists in a... say deleteB(). When you press the b button to remove, B will call this function, she knows that it is A, and then removes it A B.

  It is simpler than it seems.

  Try to test it with a basic example of justo and then move on to your project.

  I think it's very clear, but be free to ask.

• Application function rounded to the whole of the channel

  I have a channel in tiara with a large amount of values (36,000,000) contain the values on 13 decimals.

  I would like to round the value to about 4 or 5 decimal places max.

  Can someone help me understand how to do this in DIAdem.

  Example:

  0.3784729837492-> 0.37847

  I want this for each value in the channel.

  can someone help me understand how to do this?

  Thanks in advance,

  Tom

  From D-cubed method of work, but with 36,000,000 points given, it will take a lot of time.  Use the calculator.  Copy this function in the ECU for analysis, and it will happen almost instantly.  Replace the 3 by the desired number of decimal places.

  Ch("[1]/Channel") = Round (ch("[1]/ChannelToBeRounded"), 3)

  If you need a VB Script:

  Dim ChannelToRound, DecimalPoints
  
  ChanneltoRound = "[1]" / ChannelToBeRounded "  ' set the channel to round here"
  
  DecimalPoints 6 =             ' specify the number of decimals
  "This will create a new channel called"Channel"in Group 1 with the rounded values

• How can we make invisible static value in a text field to the OPA

  Hi all

  I have invisible static value in a text field in the OPA.

  For ex: field contains the value 100 while we manage the maintenance should not display the value 100 or make us the text as invisible field. whenever we submit the interview the value should be passed.

  I made the background color of the text in white field, but it reflects all the text fields. I need to make the text of the particular text as invisible field. Can someone give me a solution for it.

  Use two different attributes (the one that is indicated in the interview to the need - for example, as "the id selected user" or whatever the phrase is appropriate) and a different attribute, which is the mapped attribute.  The second attribute must not be on any screen of the interview (by thus "invisible" for the user).  Write a table of rules that concludes that the value of the attribute mapped on is EITHER static value or the selected/expected value according to some logic is appropriate to make a decision in your model of strategy.

• function round date

  cant that I round the date like that?
  or only sysdate can be rounded or if the date is stored in a variable can only be rounded
  
  Select double round('21-feb-1999','mon');

  Hello

  No, there is nothing in particular SYSDATE. Any DATE may be rounded off.

  or if the date is stored in a variable can only be rounded

  No, it does not matter if the DATE is a column, a literal, a variable, the result of a function, or any other form of expression, just as long as it's a DATE.

  Select double round('21-feb-1999','mon');

  The problem is that 21 February 1999 "is not a DATE; It's a VARCHAR2.

  TO_DATE allows to convert a DATE VARCHAR2:

  SELECT  ROUND ( TO_DATE ('21-feb-1999', 'dd-mon-yyyy')
                , 'mon'
                )       AS r
  FROM    dual;
  

  or use a literal DATE:

  SELECT  ROUND ( DATE  '1999-02-21'
                , 'mon'
                )       AS r
  FROM    dual;
  

• Can't make invisible buttons

  I am using the buttons to view the definitions of words on the mouseover.  The definition is in the balloon and is used as the label.  The definition of the watch, but I can't create the invisible button.  It shows as a solid with the label block.  I changed the appearance of no line and no fill, but nothing changes.

  What happens when you select the hand tool? The field must be set to Visible (or Visible but does not print) to interact with him, so don't set it to hidden.

• I installed the MapQuest toolbar. How can I make invisible by default when I start Firefox?

  I looked in tools/options/manage add-ons, but I don't see a way to change the default screen.

  So, you want the MapQuest toolbar? (this is rare)

  You can either make visible or not, there is no automatic way to make to hide. But I'm not 100% sure what you're asking for either.

• Math function questions

  Hello

  I am interested in some details over two routines of the advanced analysis library:

  (1) NonLinearFitWithMaxIters: what is stopped / criterion of convergence? a change in chi ^ 2 lower to...?

  By the Way, I would like to have a NonLinFit function that would allow one) to specify the error bars / b) return the number of iterations and weighing used. The latter would judge if the number of iterations specified enough by far or chance, the first to take into account the experimental or statistical counting errors.

  (2) what is the difference of the two Convolveex algorithms for the user? Y at - it a preference for one method or the other, for example time compared to memory consumption... I couldn't find such information.

  Thanks, Wolfgang

  Hi Wolfgang,.
  (1) the NonLinearFit routine is a bit complicated. We take the absolute and relative value into consideration. If the iteration stops when the absolute or relative difference research value.
  (2) 1000 data points should be considered as large in the choice of the Convolveex algorithm. The main difference between the two algorithms lies in the speed. The data that results could be consulted as the same, except the extremely small difference of digital. If you choose the FREQ_DOMAIN algorithm, the function performs an FFT first, followed by multiplication in the frequency domain, and finally the IFFT for time domain data. If the FREQ_DOMAIN algorithm will be much faster when the data set is important. (More than 10 times faster for 1000 points of data on my machine)

  Hope my answer helps.

  Best wishes
