In Flash, I can go into the properties of an image in the library and check 'allow smoothing' to enable resampling when the image is scaled or rotated.
How can I achieve the same effect for images loaded dynamically by the SWF from an external URL?
For AS2
take a look here: http://www.giordanopiazza.com/blog/flash/allow-smoothing-for-external-images-as2/
For AS3
set bitmap.smoothing = true;
