--- Comment #15 from Brion Vibber <[email protected]> 2008-12-16 20:05:54 UTC --- SVGZ is pretty ugly to handle because it doesn't have its own Content-Type... the server is supposed to serve them out with Content-Type: image/svg+xml *and* Content-Encoding: gzip... which has the added confusion that the user-agent would transparently decompress it... and if you save it to disk you'll get the decompressed version. So, even if everything's working right on the server end, when you download you may not get back the same file you uploaded. Potentially now you've got an ".svgz" file on disk which is actually not compressed... Eww! As a trivial test, I gzipped an SVG file and uploaded it to my web server, running Apache 2 on Ubuntu 8.10: http://leuksman.com/misc/test2.svgz With a stock Apache configuration, it's served out as image/svg+xml *without* the encoding setting. Firefox 3.0.3 interprets it as raw SVG, which of course is invalid XML (being a big binary blob) and doesn't render it. After adding the Apache config bits above to add the Content-Encoding header, I find that Firefox renders it now. (Yay!) But, if I save the file to disk, it saves the *compressed* version with a ".svgz.svg" extension, which now fails to load since it's marked as uncompressed but is in fact compressed. Safari 3.2.1 and Opera 9.5 render the image fine inline, but when saving to disk give me an *uncompressed* version with ".svgz" extension. So... I think things are not quite mature enough here. :( IMHO the cleanest way to go would be to transparently decompress .svgz files on upload, normalize everything to .svg, and have the web server transparently gzip .svg files when serving out, if we like, to save bandwidth. (Most of the time we don't even serve the .svg out -- we serve a .png rasterization -- so this wouldn't be a heavy burden.) -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
