Odp: FLASH: tweening skew - FLASH BUG

hi Andrew


this is a bug in the FLASH apllication


it's a conversion problem between transformation matrix and

scale/rotate/skew transform


for example:


the normal matrix:

[1.000   0.000]

[0.000   1.000]


horizontal skew done by stage area controls results with matrix:

[1.000   0.000]

[-0.954   1.000]


changed one element -> flash recognize this as

v scale 100.0 %

h scale 138.2 %

rotate h: 43.6 ; v:0

skew


this transforms (instead of matrix) are used to create tweening and results

with bad "beetween" matrixes:

[1.000   0.000]

[-0.040   1.019]


[1.000   0.000]

[-0.082   1.037]


[1.000   0.000]

[-0.125   1.052]

(data from 20 frame tween)


as you can see there are two modifications in matrix instead of one needed


1. macromedia should change flash to work with matrix not with "second hand"

transforms

2. in flash5 you can set transforms from script (?)
