Re: [Swftools-common] FileAttributes tag in SWF 8

[Du Song]

Hi, Kramm,
Thanks for the quick response.

FileAttributes tag indicates Metadata tag which is useful for SEO.
So why not keep it when writing if it exists.

I'm currently working on a small utility which reads one or more
mtasc-generated swf, then injects them into a main swf generated by
either Flash CS, mtasc or any other tools.
I know swfcombine do very good job in this. but i just want a more
neat way without too much modification to the original file.
So in my program, I just try best to keep tags in the main swf, avoid
striping any tags if i can. What i'm doing now is turn on
no_extra_tags in the source to avoid stripping of FileAttributes &
etc.
It'll be much nicer to me if there can be a switch to turn the "auto
tagging" on and off when calling swf_WriteSWF.
Thanks.

Regards,
Du Song
