Description Filip Van Raemdonck 2004-09-02 04:34:09 UTC

I changed the application/vnd.lotus-1-2-3 magic string match to:
<match offset="0" type="string"
value="\x00\x00\x02\x00\x06\x04\x06\x00\x08\x00\x00\x00\x00\x00" />
according to the information on
http://www.filext.com/detaillist.php?extdetail=wk1&goButton=Go

I checked with a random .wk1 file I found on
http://www.daniel-hertrich.de/lxgluc/ with the help of google, the magic pattern
is correct.

This might have fixed the problem outlined in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=245262; however such .tga files
are now detected as image/x-icb :-/
I'll be looking further for another solution to that problem.

Comment 1 Filip Van Raemdonck 2004-09-02 05:11:33 UTC

About the targa || icb problem: after checking image/x-icb is in fact also
listed as "Truevision Targa".
Is there any reason image/x-icb is not an alias for image/x-tga, with simply
.icb as an alternative glob?

BTW. the magic pattern for image/x-icb is also both rather incomplete because
it's too short, and inaccurate because some bytes in the pattern can have
different values for a targa file, and the byte indicating it as an actual ICB
targa file instead of another targa variant is not in the pattern from what I
found in the targa format descriptions.

I committed the lotus 123 magic stuff. I'm keeping this bug open and retitling
it for the tga issue.

Thanks for your bug report!

I've merged ICB into the TGA MIME type, and added some more extensions.
According to [1], there exist some TGA flavors.
