    Image width on adding

    real_ideveloper

      Hi all.

       

       

      I would like to know how i can figure out the width of an image after adding it to the canvas.

       

      I was trying to call the width getter method, but it returned 0.

       

      I could get width with the MOUSE.CLICK - Event, but i need it immediately after adding to the canvas.

       


      Could somebody give me an advice to solve this problem?

          If you're loading the image dynamically, you may need to wait until the complete event handler before you can access the image's dimensions.

            Hi Peter.

             

            Thank you for your fast answer.

             

            When I wait until the creation is complete and afterwards i am trying to get the width parameters with EVENT.COMPLETE handler then i get the same value of 0.

             

            Or do i something wrong?

             

            Could somebody post me an example???

              Hi,

               

              Use following code, may be this is what you are looking for:

               

              <?xml version="1.0" encoding="utf-8"?>
              <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
                  <mx:Script>
                      <![CDATA[
                          private function onImageLoadHandler(event:Event):void
                          {
                              var bmp:Bitmap = event.target.content as Bitmap;
                              trace("Height :: " + bmp.height);
                              trace("Width  :: " + bmp.width)
                          }
                      ]]>
                  </mx:Script>
                  <mx:Image source="image.png" complete="onImageLoadHandler(event)">
                     
                  </mx:Image>
              </mx:Application>

               

              Cheers

                Vikash, it was the solution.

                P.S.:

                 

                After I have read your codesnippet, I've found that the event.targent.contentWidth does the same
