pyswf's Introduction

PYSWF

A Python library for reading and writing SWF files. PYSWF is a Python port of Claus Wahlers great SWF parser https://github.com/claus/as3swf Can't thank Claus enough!

INSTALL

$ pip install pyswf==1.5.4

or:

$ git clone [email protected]:timknip/pyswf.git
$ cd pyswf
$ python setup.py install

or you might need do:

$ sudo python setup.py install

WINDOWS

Install Pillow, lxml and pylzma from a binary distribution before running setup.

Installing the *.whl files:

$ pip install the-downloaded.whl

USAGE

Basic example:

from swf.movie import SWF

# create a file object
file = open('path/to/swf', 'rb')

# print out the SWF file structure
print SWF(file)

SVG export example:

from swf.movie import SWF
from swf.export import SVGExporter

# create a file object
file = open('path/to/swf', 'rb')

# load and parse the SWF
swf = SWF(file)

# create the SVG exporter
svg_exporter = SVGExporter()

# export!
svg = swf.export(svg_exporter)

# save the SVG
open('path/to/svg', 'wb').write(svg.read())

pyswf's Issues

How can I open a dynamic swf ?

Hi,

I own a swf that need to pass parameters (flashvars), how can I do this?

Thank you!

Exception: fromstring() has been removed. Please call frombytes() instead.

Which version of PIL/Image.py should I install?

Unknown fill style type: 0xff

Problem happens when converting a SWF to SVG. (I'm running on Windows 8.1 Pro 64-bit)

Log:

Here is the SWF I used: https://a.pomf.se/rhdxca.swf

FFDec can open and parse it correctly in around 2 seconds.

I'm trying to parse the DoABC2 tag from this (https://www.dropbox.com/s/330dtevu8ug113z/malware1.swf?dl=0) file but pyswf is failing. It just get the TagEnd but not the other tags, not even FileAttributes tag. I'm using version 1.5.4.

@timknip Hi, do you still maintain this project? if it's possible, can you merge some pull request please like the PR #24.
Sorry to open an "empty" issue, but I don't find another way to contact you.
Thank you

Can pyswf generate SWF files from scratch?

I'm trying to convert some SVG files to SWF for an old web project I'm restoring (http://grafarc.org/flash/view.htm). The files themselves are very basic, just static vector outlines made mostly of straight-edged shapes.

Is pyswf capable of generating an SWF from scratch, or can it only read them from existing files? I can't quite tell from the documentation.

Not decompiling Actions?

Hi there!

I'm trying to decompile the flash that's available here [0] and it's not working as expected. I tried adding some debugging code to the action factory in actions.py and all I see is ONE call to it with a 0x07 (Stop) code; after that and for some unknown reason no more calls to the factory are made.

I also tried to modify the factory method in order to add the ActionGetURL class and it did not work (because the factory is called only once).

Any idea on what could be wrong? I'm willing to debug and help with the testing process :)

[0] http://demo.testfire.net/subscribe.swf

Add version to swf/init.py

Usually it's version, so it could be requested with swf.version

TEXTRECORDs not being read

bitmaps and other structures are imported fine, but all of the text is missing.

Export filters to SVG

Often used for strokes on bitmaps with alpha channel.

SVGExporter: initial_value must be str or None, not bytes

getting this error when trying to use the SVG exporter with python 3.11 any ideas?

TagDefineEditText is not read correctly

"data.reset_bits_pending()" is required after "self.bounds = data.readRECT()", otherwise there's 1 byte shift.
fontHeight have to be read with hasFont or hasFontClass flag. Currently only hasFont is checked.
Otherwise there's 2 bytes shift after that.
