• What is the unit allocation size that is displayed in the window to format USB?

  Original title: allocation unit size

  What is the unit allocation size that is displayed in the window to format usb

  Hi Moaz,

  Thanks for posting your question in the Microsoft Community.

  I understand that you want to know the unit allocation size that is displayed in the format USB window. Correct me if I'm wrong.

  I will certainly help the question of fixing.

  In computer file systems, a cluster is the unit of allocation of disk space for files and directories. To reduce the load of the management of data on disk structures, the file system allocates no individual disk sectors, but contiguous groups of sectors, called clusters.

  On a disk that uses 512-byte sectors, a 512-byte cluster contains one sector, whereas a 4-Kibibyte (KiB) contains eight sectors.

  Refer to the below mentioned article and see if it provides information that you are looking for.

  By default for NTFS cluster size, FAT and exFAT:

• 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.

• How to export the same MB size of my cr2 files in jpg or tiff files in Lr?

  How to export the same MB size of my cr2 files in jpg or tiff files in Lr?

  Let's say that my height is 22 MB, when I export the file in TIFF or jpg, although careful Iam with size of file settings, size, resolution, I can't manioukate how I want it.

  With jpg I tried everything, no matter what I do or a change in file size or meanless remains the same size - 7 mb instead of 22...

  Please advise,

  Best wishes

  T

  You should not even try to do it.

  JPG uses compression technology, so the files will have to be smaller than the original size of your RAWs. In addition, JPGs are 8-bit, while your RAWs are probably 14 bits, so the size needed to store your image will be smaller.

  Thus, there is absolutely nothing wrong with getting a 7 mb JPG of a 22 MB RAW.

• 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"?

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

  When I try to change my composition height and width using extendScript, it works but with anchor point at the upper left corner. How to maintain it in the Center?

  result:

  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{
    alert("Invalid argument(1):\nComp Object required.");
    }
    }else{

• 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

  });

  HI koyissa,

  I worked on what was the problem - my external publication that was created to animate dashboard was centered horizontally and vertically.

  He created the problem. When I took this out of the box of fancy worked well.
