I’m trying to find a way to remove aliasing from an Image I’m shrinking to 25% of it’s original size. I’m trying to use the JPGEncoder class from the Adobe lib package and Bitmap smoothing but it looks like it’s just making an image from a sceenshot of the aliased image retaining all of it’s distortions
heres what I got so far
any ideas?
PS. I’m using the caurina tweener class to rescale the image.
