How to determine the format of a file accessed via http?

[rmagick]

Is there any way to determine the real format of a file identified using http? For example,

Code: Select all

identify -verbose http://www.google.com/intl/en_ALL/images/logo.gif

says that the format is HTTP. Is there any way to determine that the file is actually a GIF file?

We have a patch in ImageMagick 6.3.9-0 Beta for the problem you reported. The patch will mirror world-wide within 24 hours.

And I didn't even realize it was a problem! Thanks! I'll pass this on to the RMagick user who asked me about it.

Am I missing something? I still get HTTP for the format.

Code: Select all

tim@linux:~$ identify -version  http://www.google.com/intl/en_ALL/images/logo.gif
