Just wanted to point out that Glen's response is to Omar's (similar)
question... so Omar, don't ignore this one!

Re: [Flashcoders] Using BitmapData to make a mask (AS3)

Hi,

   There are a few examples on the www about sending Bitmap data to the 
server Mario's is a good starting point - 
http://www.quasimondo.com/archives/000572.php 
  
   Anyway, there are other examples about which do 
compression/decompression on your data so you could save it into your DB 
too..


   Hope this is useful

Is there

of the bitmap?

Put the bitmap on a display container, set the .mask of the masked 
object as being that object that contains the bitmap, set cacheAsBitmap 
of both to true. So it'll be a normal masked object, but it'll respect 
the bitmap transparency (instead of using the image's box as the 
transparency mask).

You should be able to copyChannel the BitmapDataChannel.ALPHA from the image
you loaded onto the bitmap you use for the gleam. However animating this
then means moving only a single channel. Which may or may not be possible
without reprocessing the bitmapData.
It's only a rough idea, but take a look...
You could also copy the alpha channel onto all the other channels of a new
bitmapData which will give you a black silhouette which you could use as a
mask.

[Flashcoders] Using BitmapData to make a mask (AS3)

2008-08-14 Thread jonathan howe 
Hallo,

I'm loading transparent pngs in as Bitmaps and placing them within a display
object. I'd like to create a mask that is the same shape as the
non-transparent pixels, (so that I can overlay a gleam animation).  Is there
an easy way to use a Bitmap or BitmapData as a mask that respects the shape
of the bitmap?

Please lend me your awesomeness for a moment,
-jonathan
