• 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!

• Get the height and width of the jpg or png of bitmap without loading the file

  Is there a way to get the height and width of a bitmap, such as jpg or png file, without loading the complete file of the image first.

  Thank you!

  Hi JamesColeman,

  While you can't get the width and height of the jpg or png without access to the file, you can get this information without access to the entire file. A PNG for example (in raw hex) indicates the width and height of the image it contains. The first 21 bytes contain the file-specific information such as name, etc, but just after the IHDR header 4 bytes indicate the width and the other 4 bytes indicate height. If enough for you to read the first 29 bytes of the PNG to be able to get its dimensions, which, while it still requires access to the file is much easier.

  I have the code to read this information here and if you want to learn more about the specifications you can find information on this site.

  Best wishes

  To implement the above I used the code below

  var number = xfa.record.List1.List [0].nodes.length; (Does not work)

  But if var account = xfa.record.List1.nodes.length; (work)

  and also I want to delete a tag inside the < List > tag. How?

  Very Urgent.

  Thanks in advance.

  Yes, you need to use the name instead of the value to get the tag name...

• How to get the height and width of the exact text in TextLayout framework

  Hello fellow developers,.

  I'm starting to work with TLF when there are three different CFC now, I work with unique CFCS with flex 4 and a lot of things are changed as

  I use calculateHeight (), calculateWidth () now these methods are not available.

  If someone knows the replacement of these methods then do let me know.

  Thank you

  If the text exceeds the container, what can happen in a container to scroll where you have to scroll to see some of the text, then returns getContentBounds values are estimated values. It is because we do not want to force the text to recompose all the way at the end of a very long TextFlow in order to return a value. However, if you want to get the exact amount and is not afraid to take the time to redial, call textFlow.flowComposer.composeToPosition (), before calling getContentBounds. This forces all text redial at the end, and then getContentBounds displays the calculated value entirely instead of her estimate.

• 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 the length of each string in a column

  Hi all

  Is there a way to get the length of each string in a column:

  for example:

  If the table contains lines like below:

  Select 'test test1 test31' col1 of double

  Union of all the

  Select 'sectest1 sectest234' double col1

  The output should be as below:

  col1

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

  4 5 6

  8 10

  That is to say get the count of each separated from the chain of space in a column. Is this possible using regexpr_substr?

  Thanks in advance.

  Roy.

  Try the below

  SELECT LISTAGG(val1,' ') IN ONE GROUP)

  New_val ORDER BY lvl)

  Of

  (SELECT LENGTH (REGEXP_SUBSTR (col1,'[^] +', 1, LEVEL)) val1,)

  RN,

  LEVEL lvl

  Of

  (SELECT col1,

  ROWNUM rn

  Of

  (SELECT 'test test1 test31' col1 OF double)

  UNION ALL

  SELECT 'sectest1 sectest234' double col1

  )

  )

  CONNECT BY LEVEL<= regexp_count(col1,'="">
