Re: [Flashcoders] Question regarding Bitmap distorting bottom half of Stage elements
sounds like you need to use 2 bitmaps drawn with copypixels and a clipping rectangle to capture the correct half and scale the bottom half with something like the flash and math BitmapTransformer http://www.flashandmath.com/intermediate/gummy/ hope this helps a On 16 June 2011 20:48, Eric E.

Re: [Flashcoders] Question regarding Bitmap distorting bottom half of Stage elements
Hi Eric, You could try making a shell MC that is duplicated so you have two MCs with the same content right on top of each other. Then mask one so it shows on the top half and the other to show on the bottom. With the one on the bottom being a lesser z access, and covered by the top (non-distorted view) you then distort just the mc on the bottom. You could even copy the bottom MC into a bitmap image. (hiding the real bottom mc) Then you can put your transformations on that copy and just recreate the bitmap of the bottom mc as you need for updating. Then you only have to update one MCs content and both will populate. Giving you the effect you desire with a little control. Well, something along those lines anyway.
