1.) What's the cost of swftools? SWFTools is free of charge, and is released under the GPL (http://www.gnu.org/licenses/gpl.html). 2.) How to compile/link swftools? Download swftools-0.4.2.tar.gz and t1lib-1.3.1.tar.gz. gzip -d swftools-0.4.2.tar.gz gzip -d t1lib-1.3.1.tar.gz tar -xf t1lib-1.3.1.tar cd t1lib-1.3.1 ./configure make make install cd .. tar -xf swftools-0.4.2.tar cd swftools-0.4.2 ./configure make make install 3.) Is there a pdf2swf for Windows? No. pdf2swf only runs on Unix platforms, like Linux, *BSD, MacOS X, etc. There have been some successes reported on compling pdf2swf on Win32 using Cygwin (http://sources.redhat.com/cygwin), however, there's no working version yet. If you want to use pdf2swf, find a Unix machine. 4.) Is there *going to* be a pdf2swf for Windows? Probably. As soon as we find the time to look into the Cygwin compile issues. 5.) Can png2swf handle transparency? Yes. 6.) How to get Flash MX compression with SWFTools? Most tools support the -z flag for outputting compressed SWF. Furthermore you can compress/uncompress SWF files using swfcombine: swfcombine -dz file.swf -o file_new.swf compresses, while swfcombine -d file.swf -o file_new.swf decompresses. 7.) Is there a mailing list for SWFTools? There used to be, however it was shut down due to lack of traffic. The archive is available as raw INBOX file on http://www.quiss.org/swftools/list.tar.gz. 8.) avi2swf converts my avi files upside down! Try using the -p (--flip) switch.
