I have just now committed a small example of how to use a ScaleDecorator to
zoom in and out of an image. Hope this will help.

Hi Josh,
Welcome to Pivot! Have you looked at using a ScaleDecorator on
your ImageView? This may work better than adjusting the Border size. And it
has settings for the alignment (left/center/right) of the scaled image as well.
I might be able, in a couple of days, to try to implement a small example.
Sorry there isn’t one already in the examples part of the code….
Let us know,

I need help getting an image to display centered inside a larger ScrollPane.
My application displays an image that can be zoomed in and out. A snippet of
my current bxml is below. I adjust the zoom by changing the dimensions of the
Border container. When the border is zoomed out such that it is smaller than
the ScrollPane size, it's aligning to the top-left. I'd like to center it
vertically and horizontally. I've tried various combinations of TablePane,
FillPane and BoxPane as parents of the Border. BoxPane with fill:true (maybe
nested BoxPanes with opposite orientations) isn't expanding to fill the
ScrollPane as I'd expect; It shrinks to the size of the Border/Image
<ScrollPane>
<Border>
<ImageView styles="{fill: true}"/>
</Border>
</ScrollPane>
Thanks,
Josh
