NEW : We have got a new blog where we post some interesting SWF internals info.

[I can't send a message on the original issue #2464 since it was closed, so I'm opening a
new issue]
So after the fix of #2464, I did more extensive testing, and I found that in some sprites,
the linewidth is now too thick (for my usecase)...
After more exploration, I found that the zoom level impact the linewidth when exporting as
SVG (so in my case, I export with zoom level 2 so that the resulting linewidth is twice
thinner, which is what I expect).
I just wanted to point it out, I don't think it's something to be fixed ? But the
maintainers will know better than me.
Something related : the newly introduced `ffdec:original-stroke-width` attribute changes
based on the zoom level.
When exporting as SVG with the command with `-zoom 1` for the object 816 (see the linked
SWF file in #2464), if we look at the last path element for example, we have
`ffdec:original-stroke-width="0.1"` and `stroke-width="1.0"`.
If we do the same but with `-zoom 2`, the last path element have
`ffdec:original-stroke-width="0.2"` and `stroke-width="0.5"`
Not sure if it's expected or not, again the maintainers will know better.
Feel free to close this issue, I opened it mainly for documentation purpose (for my
future-self...)
Yes, this is because the Flash player displays a minimum stroke width of 1 pixel (no
matter how scaled is object on stage).
In the issue #2464, the shape had stroke width less than 1px on 100% zoom level,
that's why it was modified - the stroke-width attribute was changed to be real 1px and the
original unchanged stroke-width was placed into "ffdec:original-stroke-width" just for the
info.
Also ffdec:has-small-stroke="true" attribute was added.
It might be weird that in SVG something is different on different zoom levels,
but I tried to mimic the Flash player behavior...

Thanks for the details !

I agree with you, that seems to be the right path forward. Thanks !
