Re: [Swftools-common] Hyperlink Coords

[Hans J NUecke]

Hi Mattias (ea),
sorry for jumping in with another, but hopefully related question!
I am looking for a way to handle internal names (targets, text anchors?) with swf files. Like links to a page or URL, but to named tags in this case.

This thread might indicate a way to extract the needed information (xref info: names <-> page number) out of any status reports.

So here my questions for the experts (before I follow dead end links):
- is using -vvv and parsing the resulting messages a feasible approach for what I need? WIll that information be output? Or is swfdump a better way?
- I saw in lib\devices\swf.c  a function called
  swfoutput_namedlink(gfxdevice_t*dev, char*name, gfxline_t*points)
  Right after the functions linktopage and linktourl. My hope is, this function already does support something helpful for my needs.
  But I do not know how to make use of it and if it provides what I need.

Any hint would be highly appreciated!
Regards
Hans

Thanks Matthias,

I was going along a similar line with pdf2swf using the verbose flag (-vvv), is the following part of that output equivilent or less reliable for any reason?


TRACE   drawing link 146.00/97.00 146.00/72.00 167.00/72.00 167.00/97.00 to http://mylink.com/ (" link ")

This obviously gives us the link address as well which we also need (forgot to mention that). I was planning to parse the output to look for those lines per page and use that. Would the dimensions of the page be accurate using this approach?

Many thanks for your help.
Dan

More or less- here's what you can do:
Use "swfdump -u file.swf" to look for lines like

[007]        61 DEFINEBUTTON defines id 0016
               uses IDs: <id1>,<id2>,<id3>,<id4>

Then run "swfdump -b file.swf" to look up the respective ids <id1>:

[020]        35 DEFINESHAPE3 defines id <id1>
                bbox [0.00, 100.00, 100.00, 200.00]

This will give you the hyperlink coordinates (boxes) for each
for the links.
Lines like

[001]         0 SHOWFRAME 2 (00:00:03,994)

will be seperating the pages.

Matthias
