• Get and set the value to allow selected rolling Shuffle and facing page

  Hello world

  I work with the page and spread,

  For now, I want to value page spead shuffle and type of document.

  but I just find the function to get and set the value for the Document Pages allow Shuffle using the

  InterfacePtr < IPageLayoutPrefs > iPageLayoutPrefs (static_cast < IPageLayoutPrefs * > (: QueryPreferences (IID_IPAGELAYOUTPREFERENCES, iDocument)))

  It has no function to set and get the value of enable selected rolling Shuffle and facing page

  No one knows about it?

  I thank in advance

  There is no code for this example in the SDK or internet. Just understand and apply the concept.

• How to get and set the length and the width of the content of the layer?

  How to get and set the length and the width of the content of the layer

  All layers are packed not equal. a layer as adjustment have no limits. Layer to smart object can have two different sizes. The size of the object and the size of the object may be transformed. All smart object layers have an associated transform. To transform a smart object layers you need to work with the size of the object the generated pixels fot the layer. Text layer can be resized with a transform or by changing the font size. Pixelated layers are resize via a transformation.  The script method is resize.  When you resize the number of pixelsits made by interpolation. You can specify what method to use or set Photoshop interpolation preferably by default.

  There is also a bug in Photoshop scripts if you pause the story said make a selection and use resize. Photoshop will properly support up to a State before where you suspended history. This bug seems to be in all versions of Photoshop.

  If you look ate the script in my bug report, you should get a good idea of how to resize a layer.

• Get and set a Position of the pre-numbered WPF legend

  I'm creating a WPF application that displays a chart of data (several courses) and adds several annotations programmatically. The user has the ability to drag the annotation (InteractionMode = AnnotationInteractionModes.DragLabel) labels. I need to be able to record the new position of the label and load it later.

  I use the NationalInstruments.Controls.PointAnnotation a NationalInstruments.Controls.Graph object.

  I thought it would be reflected in the LabelAlignment, but that does not change the value that I set when I initially create the annotation of.

  Here's how I add the annotations on the graph:

  /// 
  
          /// Add the annotations to the graph
          /// 
          /// 
          ///

          private void DisplayAnnotations(DataHandler dataHandler, DateTime StartDate, DateTime EndDate)
          {
              PointAnnotation tmpAnnotation = new PointAnnotation();
              //Iterate through all the annotations in the source data set
              foreach (Post_Job_Charting.Annotation dataPointAnnotation in dataHandler.Annotations)
              {
                  TimeSpan DateDiff = EndDate - StartDate;
                  TimeSpan HalfWay = new TimeSpan(StartDate.AddSeconds(DateDiff.TotalSeconds / 2.0).Ticks);
  
                  //Only add annotations that are in the visible data range
                  if (dataPointAnnotation.Date >= StartDate && dataPointAnnotation.Date <= EndDate)
                  {
                      tmpAnnotation = new PointAnnotation();
                      tmpAnnotation.HorizontalPosition = dataPointAnnotation.Date;
                      tmpAnnotation.VerticalPosition = dataPointAnnotation.Value;
                      tmpAnnotation.Label = dataPointAnnotation.Text;
  
                      if (dataPointAnnotation.Date.Ticks < HalfWay.Ticks) { tmpAnnotation.LabelAlignment = new AnnotationLabelAlignment(BoundsAlignment.None, 0, -25); }
                      else { tmpAnnotation.LabelAlignment = new AnnotationLabelAlignment(BoundsAlignment.None, -75, -25); }
                      tmpAnnotation.InteractionMode = AnnotationInteractionModes.DragLabel;

                      else { tmpAnnotation.Visibility = System.Windows.Visibility.Hidden; }
  
                      //Tag the annotation so I can find it later
                      tmpAnnotation.Tag = dataPointAnnotation.ID;
  
                      //Display annotation on the graph
                      niGraph.Children.Add(tmpAnnotation);

          }
  

  Once I have the position of the label, I need to be able to reset the label to this post, but let's start first of all, I need to get this job.

  Any help you can offer would be greatly appreciated.

  Best regards

  -Marcel

  There is no property on the annotation of point that sets the position of the label. I created a task to look by adding this.

  However, you can monitor the changes using a custom BoundsAlignment application that registers the new offset as it is updated:

  public sealed class RecordingBoundsAlignment : BoundsAlignment {
        public Vector LastOffset { get; private set; }

  public override Point AdjustPosition( AlignmentArgs args ) {
            LastOffset = new Vector( args.XOffset, args.YOffset );

  return None.AdjustPosition( args );
        }
    }

  When you create the annotation, you use an instance of the alignment of the record, and when you want to store the position you will be able to read the value of the recorder:

  tmpAnnotation.LabelAlignment = new AnnotationLabelAlignment(
        new RecordingBoundsAlignment( ),
        initialXOffset,
        initialYOffset );

  // ...

  var recorder = (RecordingBoundsAlignment)tmpAnnotation.LabelAlignment.Alignment;
    Save( recorder.LastOffset );

• How to get and set the size of the pool AM in life

  Hi, I want to get and programmatically, set the following parameters:

  
  

  ------------------------------------------------------------------------------

  Size of the initial Pool (jbo.ampool.initpoolsize)

  Maximum Pool size ( jbo.ampool.maxpoolsize )

  Referenced Pool size ( jbo.recyclethreshold )

  --------------------------------------------

  
  

  In AMImpl or other place?

  
  

  Is it methods?

  
  

  Thank you.

  To get information about the pool, you can use code like this in your applicationModuleImpl

• How focus a JavaFX Group properly and set the pivot (reverse) by using translations in 3D space?

  Description:

  I m referring to the Oracle tutorial http://docs.Oracle.com/JavaFX/2/transformations/jfxpub-transformations.htm using the transformations.zip source code, which is available for download on this page. I Don t understand why they Center the xylophone in space 3D like this and why they calculate the pivot (reverse) using translations. So they are creating a large number of groups, including rectangles, representing the xylophone, in addition to finally to a group called "cam".    

  class Cam extends Group {     
       Translate t  = new Translate();     
       Translate p  = new Translate();     
       Translate ip = new Translate();     
       Rotate rx = new Rotate();     
       { rx.setAxis(Rotate.X_AXIS); }     
       Rotate ry = new Rotate();     
       { ry.setAxis(Rotate.Y_AXIS); }     
       Rotate rz = new Rotate();     
       { rz.setAxis(Rotate.Z_AXIS); }     
       Scale s = new Scale();     
       public Cam() { 
            super(); getTransforms().addAll(t, p, rx, rz, ry, s, ip); 
       }     
  }    
  
  final Cam camOffset = new Cam();    
  final Cam cam = new Cam();    
  ...    
  camOffset.getChildren().add(cam);    
  ...    
  final Scene scene = new Scene(camOffset, 800, 600, true);    
  ... 
  

  The Group "cam" is added to another group called "camOffset", which is added to the 'scene' as root the node.

  Until there , everything is understandable to me, but there is a method, called "frameCam (.)" which calls 4 other methods: ""

  public void setCamOffset(final Cam camOffset, final Scene scene) {         
       double width = scene.getWidth();         
       double height = scene.getHeight();         
       camOffset.t.setX(width/2.0);         
       camOffset.t.setY(height/2.0);     
  }

       final double pivotY = bounds.getMinY() + bounds.getHeight()/2;         
       final double pivotZ = bounds.getMinZ() + bounds.getDepth()/2;         
       double width = scene.getWidth();         
       double height = scene.getHeight();         
       double scaleFactor = 1.0;         
       double scaleFactorY = 1.0;         
       double scaleFactorX = 1.0;         
  if (bounds.getWidth() > 0.0001) {            
       scaleFactorX = width / bounds.getWidth(); // / 2.0;        
  }        
  if (bounds.getHeight() > 0.0001) {            
       scaleFactorY = height / bounds.getHeight(); //  / 1.5;         
  }

       scaleFactor = scaleFactorY;         
  } else {            
       scaleFactor = scaleFactorX;         
  }        
       cam.s.setX(scaleFactor);         
       cam.s.setY(scaleFactor);         
       cam.s.setZ(scaleFactor);     
  }

  If the method ' setCamScale (...) 'is understandable,' setCamOffset (...) ' puts the root node ('camOffset') in the center of the screen, but I Don t understand the 2 following methods at all. Of course, the child ("cam") is not centered, by putting just the root node ('camOffset') in the center of the screen, but how they focus the xylophone / "cam" and set the pivot, using translations:

  Questions:

  1. Why they use 3 different translations (', 'ip', 'p')?
  2. Referring to ' setCamPivot (...) ': Why they are the first translation of 'cam.p' to "pivotX", 'pivotY' and 'pivotZ' and then 'cam.ip' to '-pivotX', '-pivotY' and '-pivotZ' (marked in the source code with * 1 * and * 2 *)? Should he not just put the Group at his position, where it has been positioned before, as if the method has never been called? That would be my guess, because I expect that an object is placed in the same position as before, if I first move with the values X, Y, Z and then return with the same values - X, - Y, - Z in the opposite direction.
  3. Even with the method ' setCamTranslate (...) ' ': Why use another translation "cam.t", moving the Group ("cam") with the same values "-pivotX', '-pivotY' (and not '-pivotZ'), which they used in the"setCamPivot (...) method `?

  Annotations:

  Of course it works, the xylophone is located in the center of the screen and could turn perfectly, without change of rotation point / pivot point, but I Don t understand how they did it. I read everything about layoutBound, boundsInLocal, boundsInParent, blogs about page layout and page layout goes into javaFX https://blogs.oracle.com/jfxprg/entry/the_peculiarities_of_javafx_layout and http://amyfowlersblog.wordpress.com/2011/06/02/javafx2-0-layout-a-class-tour/ and finally a large number of questions to stackoverflow, but I still Don t understand the meaning behind the methods stated.

  Before the call of ' frameCam (...) ', they ask:

  double halfSceneWidth = 375;  // scene.getWidth()/2.0;     
  double halfSceneHeight = 275;  // scene.getHeight()/2.0;    
  cam.p.setX(halfSceneWidth);    
  cam.ip.setX(-halfSceneWidth);    
  cam.p.setY(halfSceneHeight);    
  cam.ip.setY(-halfSceneHeight); 
  

  I deleted these lines, because it doesn't change anything.

  The base in place, is that there are three defined different rotations, one around each axis. Of course, these could be combined into a single rotation, but doing so would make the geometry in the mouse dragging very complex managers. As it is, the degree of rotation around each axis can be calculated and changed independently.

  In general, the rotations are defined by an angle, an axis and a (pivot) point. The axis is a 3D vector and goes through the pivot point; the rotation is around this axis through that point.

  In the configuration in the example, the pivot of each of the individual rotations is set to the default (0,0,0). Because we really want the rotation to be around the center of the group, not the original, the Group translates first point appropriate pivot (ip), the rotations are applied then (around (0,0,0) after translation by ip), then the group is reflected in its location of origin (p). These operations are not commutative, yes show ip, then the rotation, then p is not the same as when you run ip, then p, then the rotation (in the second, ip and p would cancel and rotation would be about (0,0,0) instead of around the Center).

  For good measure, there is a scale, that is also applied after ip (so that scaling occurs from the Center, not the original) and then a final translation.

  The final effect is that there is a lot of transformations that can be controlled independently. There is a scale (s), a rotation about each axis (rx, ry, rz), and a translation (t). The p in translations and its inverse ip are just "housekeeping" to ensure that rotation and scaling are done from the center of the screen, instead of (0,0,0).

  So:

  1. Why they use 3 different translations (', 'ip', 'p')?

  p and ip are translations for the rotation and scaling are done from the Center and not to the origin. t is a general translation, the user sees.

  Referring to ' setCamPivot (...) ': Why they are the first translation of 'cam.p' to "pivotX", 'pivotY' and 'pivotZ' and then 'cam.ip' to '-pivotX', '-pivotY' and '-pivotZ' (marked in the source code with * 1 * and * 2 *)? Should he not just put the Group at his position, where it has been positioned before, as if the method has never been called?

  He puts the group to its original position, but other changes are between p and ip. These transformations behave differently (in a planned way) because the group is translated when they are applied.

  Even with the method ' setCamTranslate (...) ' ': Why use another translation "cam.t", moving the Group ("cam") with the same values "-pivotX', '-pivotY' (and not '-pivotZ'), which they used in the"setCamPivot (...) method `?

  The t values are changed in the mouse Manager (with alt-middle mouse button-drag, which I can't test actually using my trackpad...). As you have noted, the effect of p and IP translation cancel out, so we end up with t, which can be changed by the user. They could have combined t and p a single transformation, but updated since the mouse Manager would have been more delicate, and the intent of the code would be less clear.

• Create bookmark and set the Page Destination Script

  Greetings,

  I created a batch Script that will create children bookmarks and set the destination page.

  Bookmarks are listed in the script in the order in which they appear in ascending order.  (for example, Name1, name2, Name3, name4)

  However, once the script is run, the bookmarks are inserted in descending order. for example (Name3, name4, Name1, name2).

  Can someone advise please how do I get the script to create bookmarks in ascending order, as noted in the script?

  var bm =
  this.bookmarkRoot.createChild ("Name1", "this.pageNum = 0");
  this.bookmarkRoot.createChild ("Name2", "this.pageNum = 1");
  this.bookmarkRoot.createChild ("Name3", "this.pageNum = 2");
  this.bookmarkRoot.createChild ("Conjoint4", "this.pageNum = 3");

  var bm = this.bookmarkRoot.children [0];

  BM. Color = color.red;

  The script should also be changed to all bookmarks in red color.  The script for color bookmarks only works on the first bookmark.  Any intervention on changing the script for this would be most appreciated as well?

  Thank you.

  Use something like this:

  var bm;

  this.bookmarkRoot.createChild ("Bill Smith","this.pageNum = 0", 0); BM = this.bookmarkRoot.children [0];

  BM. Color = color.red;

  this.bookmarkRoot.createChild ("David Smith", "this.pageNum = 1", 1 "); BM = this.bookmarkRoot.children [1];

  BM. Color = color.red;
