How do you do the pdf 2 swf conversion

Hi, your latex editor is really great. I have a question about how you handle the conversion process. I want to be able to generate single latex formulas offline as well and I need swf files with a transparent background just like you provide. Currently I'm able to do this using pdflatex followed by pdf2swf and then removing the background by hand with swfextract. Unfortunately this is very complicated, since I need to check which index the background inside the swf file has (it's changing from file to file) in order to remove it. Your software is doing this automatically. What converter do you use?

I would be very glad if you could tell me.

Try using the "-s transparent" option with pdf2swf

Thanks a lot. Works perfectly. I'm wondering why they did not mention this option in their faq and instead describe that way using swfextract.
