Re: [flexcoders] Masks, Filters, Soft Wipes

In case anyone else is interested, the solution to the bitmap cached  
mask issue is to make the mask a sibling of the target, rather than a  
child of the target, in the display hierarchy.


Then you can position it as you wish and it filters properly.

 Sure enough, that creates a nice feather on the mask. Trouble is  
that

 the mask now refuses to be rendered in negative space. Even though I
 can trace the mask co-ordinates and verify they are in negative
 space, the mask shape renders on screen as if it was set at 0, 0.

I've tried a few combinations of this, and I give up. Seems like the
mask just won't go into negative space if it has bitmap caching turned
on (either cacheAsBitmap=true or at least one filter applied).

Hi,

Can anybody help shed some light on an odd problem with filters? I  
want to create soft edge wipe effects. I've got a pretty good proof  
of concept that works like so:

target.cachePolicy = 'on'
mask.filters = [new BlurFilter(20,20)]

Sure enough, that creates a nice feather on the mask. Trouble is that  
the mask now refuses to be rendered in negative space. Even though I  
can trace the mask co-ordinates and verify they are in negative  
space, the mask shape renders on screen as if it was set at 0, 0.

Removing either of the above lines fixes the problem (but then, so  
soft wipe of course).

Anyone understand why this should be?
