Powerpoint to SWF

Is ist possibe to convert powerpoint files (ppt or pptx) to flash fila swf using aspose.slides java, aspose.flash java or aspose.total java?

Actually not; but you can take slide images of presentation with Aspose.Slides for JAVA. Then you can insert those images in SWF file by using any third party java library that could handle swf files.

But i want to extract the texts from the swf file after conversion.

You can convert slide to svg and if I’m not mistaken I saw something
open source on Internet for converting svg to swf.

Do you mean, first I can convert slides to svg using Aspose.Slides for Java and then svg to swf using another third party java library?

Yes, exactly. The only problem is to find this third party library.
