SWFTOOLS

SWFTools is a collection of utilities for working with Adobe Flash files (SWF files).
The tool collection includes programs for reading SWF files, combining them, and
creating them from other content (like images, sound files, videos or sourcecode).
SWFTools is released under the GPL.
The current collection is comprised of the programs detailed below:

• PDF2SWF
  A PDF to SWF Converter. Generates one frame per page. Enables you to
  have fully formatted text, including tables, formulas, graphics etc. inside your
  Flash Movie. It’s based on the xpdf PDF
  parser from Derek B. Noonburg.

  A multi-function tool for inserting SWFs into Wrapper SWFs, contatenating SWFs, stacking SWFs
  or for basic parameter manipulation (e.g. changing size).
• SWFStrings
  Scans SWFs for text data.
• SWFDump
  Prints out various informations about SWFs, like contained images/fonts/sounds,
  disassembly of contained code as well as cross-reference and bounding box data.
• JPEG2SWF
  Takes one or more JPEG pictures and generates a SWF slideshow from them. Supports
  motion estimation compression (h.263) for better compression of video sequences.
• PNG2SWF
  Like JPEG2SWF, only for PNGs.
