• 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!

• Can I turn off the setting that displays the height and width in a small black box when you use the marquee selection tool?

  In Photoshop CC on a mac...

  When you use the marquee selection tool, a little black box appears next to the cursor and displays in real time, the height and the width of the selection.  The same annoying box also appears when you drag an item with the tool move, displaying the numeric position of the cursor.  Is there anyway to disable the display of this little black box?  It makes me crazy.

  In cmd/ctrl-k preferences click "Interface". At the bottom of the interface user is a drop down menu to see the transformation. The value as 'never '.

  

• 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.

• 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.

• 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

• What is the best way to resize an image, but keep the height and width of the same original size or format?

  What is the best way to resize an image, but keep the height and width of the same original size or format?

  I tried to use the function of the size of the Image, but when I changed the size of the image, the width has not changed with it.

  Thanks for the tips!

  Hi Landon.Luu,

  You want to keep the relationship between the width and height to be the same?

  Click the constraint between width and height to keep the ratio intact.

  

  Kind regards

• The height and width settings no longer work.

  Adobe Photoshop CS5 settings went crazy in the canvas size box.  Everything appears as 0, whether inches, pixels, etc.  I tried to enter numbers instead of the zeros in the height and Width boxes, and then it creates huge margins around the image.  If I cut the number in half to try to mislead the it, it still gives big margins instead of cropping the image.  Help!

  Looks like you have Relative checked in the canvas size dialog box.
