Resizing Image doesnt work

Hi all

here is my code. I have an Image on a Container with RowLayout, the problem is, I have tried using Image.setActualSize(Number,Number); OR Image.width and Image.height, but it doesn't have any effect on the Image.

The seize of the image follows the size of the original image.

 

var foregroundLayout:RowLayout= new RowLayout();
foregroundLayout.type=RowLayoutType.VERTICAL;
foregroundContainer.setActualSize(screenWidth,screenHeight); //set foregroundLayout as the layout of foregroundContainer foregroundContainer.layout=foregroundLayout;
[Embed(source="/../assets/images/start_image.png")] //ORIGINAL IMAGE SIZE IS 240x320
var startPNG: Class;
var startImage:Image=new Image();
startImage.setImage(new startPNG()); startImage.setActualSize(100,100); //THIS LINE DOESNOT HAVE ANY EFFECT //add startImage to foregroundContainer foregroundContainer.addChild(startImage);

 

 

I have spent the last hours trying to figure it out but i still cant.

 

Any thoughts on this? Thanks.

Try adding this line:

 

startImage.setActualSize(100,100); //THIS LINE DOESNOT HAVE ANY EFFECT
startImage.invalidateProperties();

Re: Resizing Image doesnt work

Well, that's why I said to "try it" - I don't yet fully understand all the lifecycle methods of the Flex framework, but in some of my apps, the invalidateProperties() call has been "necessary" to force the display tree to get re-measured and re-laid out so that component sizes that I set are honored.  I have some white papers and presentations bookmarked to go read so I understand it better, because I hate doing cargo cult programming, but sometimes finishing a bigger task means being "pragmatic" about going with things that "seem" to be needed.

 

Maybe if you post your sample code here, I or someone else can experiment with it and get it to work.

Re: Resizing Image doesnt work

figured it out,

I changed the layout to GridLayout..

And I create a GridData for every single control hosted within.
