Scale an image in as3?

I have a bitmap in as3, I want its height to be 800, I want the width to be adjusted with the correct ratio so the image doesn't look squashed. How can I do this programatically in as3?

myImageBM.height = 800;
myImageBM.width = ??

Simply:

myImageBM.height = 800;
myImageBM.scaleX = myImageBM.scaleY;

Hope you'll find this usefull!!

Try: 

myImageBM.height = 800;
myImageBM.width = myImageBM.scaleY * myImageBM.width;

This is assuming you are just displaying it. For further processing of the image I would apply a matrix to it's bitmap data.

Of course if you are dealing with both portrait and landscape images it would be slightly more complicated, but the general idea is you set either height or width, then use the bitmap's scale properties to adjust the other dimension.
