So am I.  Maybe as/when/if my knowledge of 'c' and the various
internals improves, I'll be
able to actively submit patches and make contributions, etc, etc.
Time is always a factor,
plus, as I get older, the less I like being sat at a computer!!

The wiki is the place to start then,


Mattias will only too pleased to have your input in whever form it takes.

Sorry!  Typo! ( smacks self on hand! ).  Typing,

    swfdump -X -Y  yourfile.swf

will give you the dimensions of the swf you are interested in.  Hence
I was saying, try a conversion, then use swfdump to check what
happens.  If you see a difference, then
you have answered your own question.  Tral and error, and a process of
works wonders, even for an end-user.

Trial an error!  Featues come and go. Type the following command and
see what happens,,

   pdf2swf -s ppmdpi=100 yourfile.pdf -o yourfile.swf

See above.

Again see above! ;o)

There is a lot I don't know about PDF's or Flash file format myself.
Much like you,
