• Get the height and width of an image

  I have therefore some images in my program that I'm loading. These images are much longer than the size of the screen. So I put in a ScrollView. My question is how can I get the height and width of an image. The image.width and image.height doesn't return the correct values.

  //add the image
  private function addImage():Container {
      var sp1:Container = new Container();
      sp1.sizeUnit = SizeUnit.PIXELS;
      sp1.debugColor = 0xFFFFFF;
      sp1.margins = Vector.([1,0,0,0]);
      sp1.align =ContainerAlign.NEAR;
      //sp1.setSize(650, 800);
  
      var myPattern:RegExp = / /g;
      var fileName:String = "./com/swiz/img1.png";
      var icon:Image = new Image();
      icon.setImage(File.applicationDirectory.resolvePath(fileName).url);
      //icon.setPosition(0,0);
      //icon.setSize(320,800);
      sp1.addChild(icon);
      sp1.setSize(650, icon.height);
  
      return sp1;
  }
  

  and my code scrollview is

  //add to the scrollView
  var scroller:ScrollPane = new ScrollPane();
  scroller.width = 650;
  scroller.height = 505;
  scroller.y = 0;
  scroller.addScrollContent(addImage());
  addChild(scroller);
  

  Thanks in advance!

  Hey shethab,

  in order to retrieve the height and width of your image, you must use use the an event listener on your image and check for the Event.COMPLETE event. What is happening because the image you upload is not built, it takes time to load into your application using the setImage() method. and when you check the width height after the setImage method, the image was not loaded and has no height and width to this second. If you use the event listener, you can retrieve the height and width as it was finally loaded.

  Try the following code:

  import flash.events.Event;
  
  //add the image
  private function addImage():Container {
      var sp1:Container = new Container();
      sp1.sizeUnit = SizeUnit.PIXELS;
      sp1.debugColor = 0xFFFFFF;
      sp1.margins = Vector.([1,0,0,0]);
      sp1.align =ContainerAlign.NEAR;
      //sp1.setSize(650, 800);
  
      var myPattern:RegExp = / /g;
      var fileName:String = "./com/swiz/img1.png";
      var icon:Image = new Image();
      icon.setImage(File.applicationDirectory.resolvePath(fileName).url);
      icon.addEventListener(Event.COMPLETE, onImageLoaded);
      //icon.setPosition(0,0);
      //icon.setSize(320,800);
      sp1.addChild(icon);
      sp1.setSize(650, icon.height);
  
      return sp1;
  }
  
  private function onImageLoaded(e:Event):void
  {
      trace("image height: " + e.target.height + " image width: " + e.target.width);
  }
  

  hope that somethings brightened. Good luck!

• Minimum height and width does not work in the responsive project

  I'm working on a responsive project in Captivate 9, breakpoint Office, for one of the items minimum height 50px and Minimum width to 50px.

  In points out of office and Tablet, she gets no smaller than 50px. However, breaking Mobile, point it turns into 32px Min-Height and Min-Width 4.0px.

  The 32px Min-Height and Min-Width 4.0px take a coral color in the breakpoint Mobile.

  Why don't the 50px which was update to stop Office remain the same on all breakpoints?

  What is the purpose? A 50 x 50 pixel png? I just create a project that is sensitive with a png of 200 x 200, placed in the desktop view and then set the size of the object and the height to 50 pixels. When I pass between breakpoints, the size remains the same. The size and position properties are all a light purple color on each breakpoint, which I guess means that these attributes are inherited from the Office discovers.

  If the boxes under "Height" and "Width" have transformed a coral-colored, I guess that means that these attributes have been changed for this breakpoint.

  And you obviously already know. I guess that I'm just trying to say that he expected to run, as it does for me!

  You are able to adjust these modified figures go back to your desired size? The same thing happens if you create, say, a dynamic square object in the view of the Office? Have you tried right clicking on the object in the desktop view and selecting "Apply position properties from all points of view"?

• Animate FancyBox iframe in Edge - do not show the correct height and width

  Hi all

  Can someone please provide advice or a solution to this problem.

  I tried to use the edge Fancybox.js animate to call an iframe (as a pop up album).

  However when I try this it does not show the correct height and width properties - even though I am their definition.

  When I test this on my hard drive it works fine in Chrome and Firefox. But when tried on line on a test server I get a slim pop up that has not properly set the height.

  Would be - because the iframe is pre-configured before composition/html page first affecting the size?

  Help, please

  CODE USED:

  $. fancybox.open)

  {

  type: "iframe"

  autoScale: 'false. '

  height: '600'.

  Width: '600',

  HREF: 'llink.htm site publication. "

  }, {

  padding: 0

  });

• How to set the size (height and width) 100% swf

  Hi all

  Here, I want to put my SWF height and width to 100%.

  If I want to increase my height by hanging out on my corner SWF then automatically the width should change.

  If the two should be 100% in all cases. How to get there.

  In the browser? Flash can not set the size of itself - its size is defined in the HTML code. You must use JavaScript to set the Flash object width and height on window resize event.

• show the height and width of the screen

  Is it possible to display the height and width of the screen in a labelfield?

  Yes. To do this, ask yourself two questions:

  (1) is it possible to display a string that I want in a LabelField? (The answer is Yes)

  (2) is it possible to set the height and width of the screen in a string? (The answer is Yes)

  (3) is it possible to find the height and width of the screen? (The answer is Yes)

  Now, just try to find how to do it ask these three questions. #1 is right there in the documentation for class, LabelField . #2 is trivial if all goes well. # 3, take a look in the view class.

• How keep the anchor in the Middle during the change of height and width for extendscript model?

  Thank you

  OK, here is therefore the function for resizing of the model code. I tested several times with anchor points are offset on layers and centered, even with layers that are not yet within the limits of the Model Viewer. I'm sure there will be some users who eventually find something that will break it, but for now it seems to work perfectly.

  app.beginUndoGroup("CompResize");
    var myComp = app.project.activeItem;
    resizeComp(myComp, 500, 500);
  app.endUndoGroup();
  /* TESTING ABOVE */
  
  function resizeComp(compObj, newWidth, newHeight){
    if(typeof newWidth == "number" && typeof newHeight == "number"){
    if(compObj instanceof CompItem){
    var locData, allLayers, allLayersLen, curLayer, clAP, clPos, xShift, yShift, oldCW, oldCH, clH, clW, xOff, yOff;
    pData = new Array();
    cWidth = newWidth;
    cHeight = newHeight;
    allLayers = compObj.layers;
    allLayersLen = allLayers.length;
    oldCW = compObj.width;
    oldCH = compObj.height;
    compObj.width = cWidth;
    compObj.height = cHeight;
    for(var i=1; i<=allLayersLen; i++){
    curLayer = allLayers[i];
    clW = curLayer.width;
    clH = curLayer.height;
    clPos = curLayer.transform.position.value;
    clAP = curLayer.transform.anchorPoint.value;
    xShift = (oldCW - cWidth)/2;
    yShift = (oldCH - cHeight)/2;
    curLayer.transform.position.setValue([clPos[0] - xShift, clPos[1] - yShift]);
    }
    }else{
