Apologies in advance for asking this question - I’m there’s an answer somewhere on the forum, but I can’t find it.
What i would like to do is create a movie clip (preferably on the timeline so I can motion tween it, but created dynamically if that’s how it has to be done) that blurs the clip on the timeline layer beneath it (the clip to blur will probably be a bitmap).
I have read up on the Blur filter and can apply it directly to a clip using code of the form:
import flash.filters.BlurFilter;
var blurred:BlurFilter = new BlurFilter(5, 5, 4);
var storedBlur:Array = [blurred];
myClipToBlur.filters = storedBlur;
but I don’t understand how to blur only a section of a clip, the section being that which is ‘underneath’ another ‘blur masking’ clip.
I hope I’ve made this easy to understand. Thanks in advance to anyone who can help.
