flash shape to svg

Intro

I have made a script to convert a flash shape to svg (the easy way).

I hope it converts all flash shapes, because the shape I needed it for only contained “moveTo“, “splineTo” and “lineTo” functions.

Requirement

This script requires a dump from swftools‘ swfdump:

swfdump -D test.swf > test.dump

The script

import sys

f = open(sys.argv[1])
l = f.readlines()
f.close()

res = """<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" version="1.1" id="svg2">"""

res += '<path d="'

for line in l:
    line = line.replace('\n', '').replace(')', '').replace('(', '')

    analyse = line.split(' ')[-5:]

    if analyse[0] == 'splineTo':
        res += "Q%s,%s %s,%s " % (analyse[1],analyse[2],analyse[3],analyse[4])
    else:
        analyse = analyse[2:]

        if analyse[0] == 'moveTo':
            res += "M%s,%s " % (analyse[1], analyse[2])

        elif analyse[0] == 'lineTo':
            res += "L%s,%s " % (analyse[1],analyse[2])

res += 'Z" style="fill:#000000"/>'
res += "</svg>"
print res

Usage

python shape2svg.py /path/to/your/dump > /path/to/your/svg

The svg will contain one element with a path that should create the same shape.

Feedback

If any shapes do not convert properly, I’d love to hear about it: Talk to me at identi.ca/cpf
