infinite zoomability (no bitmap conversion) and smallest possible
file size, and if the file doesn't contain transparency groups
or any other features which have no direct SWF equivalent (pdf2swf
will output an "unsupported" warning).
Use -s poly2bitmap if you need somewhat faster conversion speed,
only need zoomability up to a certain level (specify with -s zoom),
or if the normal pdf2swf or pdf2swf --flatten complains about
unsupported features (-s poly2bitmap uses a bitmap renderer and
hence can deal with more PDF features (like multiply blended
transparency etc.).
I do realize that the option multitude of pdf2swf is quite
confusing right now- after the next release, I plan to integrate a more
intelligent conversion behaviour, in particular switching to
different render modes automatically depending on the features
of the input file.
My typical recommendation for scripting pdf2swf conversion on
systems where conversion time isn't crucial is the following
threefold fallback:
pdf2swf [...options...] -s breakonwarning --flatten file.pdf -o file.swf || \
pdf2swf [...options,zoom...] -s poly2bitmap file.pdf -o file.swf || \
pdf2swf [...options,zoom...] -s bitmap file.pdf -o file.swf
Something similar to this will probably be hardcoded into pdf2swf at
some point in the future.
