FLASH: Tween Bug?

[Byron Canfield]

I have discovered what I believe to be a bug in shape tweening; that, or it

may simply be a limitation.


I set up an example of how to simulate tweening an increase of kerning by

breaking apart two text strings that have different kerning values applied

and then shape tweening between them. (This was in response to another

user's query.)


I decided to decrease the 528x60-pixel stage size to only what was needed

to display the tween (504x36), which I did by turning on the multiple frame

edit and selecting all object, and then using the inspector, moving

everything up and to the left by 12 pixels, then modifying the stage size

accordingly.


It would seem the mere act of reducing the stage size is causing the first

letter to shape tween improperly such that it now needs shape hints. The

results (both SWF files) can be seen at

http://www.canfieldstudios.com/flash3/tweenbug/.


These are identical files, in every respect, save that the objects have

been all moved up and to the left, and the stage size decreased.


On possibility is that it has something to do with the curves requiring

bezier control points (non-accessible to the user) that extend outside the

stage area. But if so, why are other letters not affected? Perhaps it's

only ones that extend outside the top and left side of the stage?
