Question about BMP and ActionScript...
I've read in a few places about how ActionScript allows for "caching of objects as internal bitmap representations of instances" using the cacheAsBitmap property. Also, the BitmapData class allows for creating and manipulating arbitrarily sized transparent or opaque bitmap images...
First of all, what does the "caching of objects as internal bitmap representations" mean exactly?
Secondly, when it's said that the BitmapData class can create transparent bitmap images, are "they" referring to actual bitmap imagery which supports transparency or is this instead being used to describe some sort of generic way of thinking about creating an image using a class within ActionScript? I guess I'm just shocked that BMP files supposedly support transparency when usually I see an immense advocacy for PNG usage in this sort of image attribute need.
