I'm exporting ppt to pdf (using openoffice) then converting the pdf to swf (using swftools).
I noticed that for pure english files, if I use the above method, the generated swf is comparable to pdf in size. However, for most of my foreign language files, the generated swf size is much bigger. I have a pdf , 367kb, in english and chinese (exported from ppt), but the generated swf is almost 5mb. Whereas, if I directly export this file from ppt to swf using openoffice, the generated swf is only 142kb.
The command I ran was as follows
> pdf2swf -T --flashversion=7 -z --zlib -F --fontdir=\WINDOWS\Fonts Lnopic.pdf -o Lnopic.pdf.swf
The version of swftools I use is 0.7.
Clues?
