Hi,
what needs to be changed in the script if bitmap isn’t placed in point 0,0 but in the centre of the movie clip?

this technique can use in a game?., for example a maze game., i’ll make a map in one .png file, then the other object can pass on the non pixelated parts of the map., do i make sense?

Hi. This is a great article and exactly what I was looking for.

I am having trouble understanding the source code however.

Are you using a created BitMapDataObject, checking it, then creating a BitMapObject of the already created bitmapobject and measuring again? Sorry, Ive only been using AS3 for 4 months, but loving it.

Im working on a project at the moment, and my understanding of this is critical.

Another way to this is to define a Sprite as a custom hitarea for a PNG Image. I wrote a simple function that generates a sprite out of a PNG Image with transparent regions: http://www.webverwirklichung.com/en/blog/programming/flex/creating-hitarea-png-image-transparent-alpha-regions-flex
