Image width, height.

[=?iso-8859-1?q?Premshree=20Pillai?=]

Hello,

Is there a Py module available using which I can find
the width and height of any image format?

Hello,

try 'identify -format "%w %h"' with popen.

identify is part of imagemagick.

Sorry, that's no python module, but maybe it
helps you, too.

HTH,

ANY image format is a tall order, however PIL is pretty good at it, and
supports a large number of image formats.
(227, 149)

Note that even if you don't have a JPEG decoder available, PIL bakes in
enough support for the format to let you get the image dimensions out
of the header. I'd imagine that this is generally true with the rest
of PIL, too.

I'm not aware of one short of loading the whole image or shelling out
to another tool.

There's a nifty Perl module though:
http://www.blackperl.com/Image::Size/
The nice thing about it is it doesn't have to load the whole image in
most cases. The actual size determining code is about 500 lines of
fairly simple Perl to handle about 10 image formats. It might not be
too bad to port it. It's under the Perl Artistic License.

PIL is such a Python package. It doesn't load the entire image if all
you want to know are the dimensions.

Can't PIL do this?
