how to bend text in as3?

I have a text 'hello world' in my ActionScript3 file.

What I am trying to achieve is to make the middle portion of the text bigger in height.

So, it will start off with a small 'h' and then moving towards the middle, each letter's size will increase.

The exact thing is shown in this image -

Any ideas how I can achieve this? Than开发者_C百科ks in advance.

Because this has per-glyph distortion, the only way to do it correctly is with a DisplacementMapFilter (which would actually work well with animation too). Here's a good example on how to do that.

You could use drawTriangles from Graphics object. First, create a BitmapData and do a copy of your TextField (enlarged). Then you just have to map your BitmapData to a bended mesh (made of triangles).

If I had to do this, I would put every character in a separate TextField, every TextField in a Sprite, set a proper font size for every character, place the Sprites on proper positions and distort the Sprites using whatever methods you need (Transformation Matrix, 3D, whatever).
