could not load matplotlib icon

It looks like the problem is happening because your version of GTK does
include a GDK pixbuf loader for SVG files.

You can disable the message by editing the installed backend_gtk.py
(or editing the source file
matplotlib\lib\matplotlib\backends\backend_gtk.py
and reinstalling)
and changing
"verbose.report_error('Could not load matplotlib icon: %s' %
sys.exc_info()[1])"
to
"verbose.report('Could not load matplotlib icon: %s' %
sys.exc_info()[1])"
or just "pass".

The fix has also been applied to CVS.

Hi,

I keep getting this error when my matplotlib gtk app starts up:

Could not load matplotlib icon: Couldn't recognize the image file
format
for file 'C:\Python23\share\matplotlib\matplotlib.svg'

I don't *think* it's my fault. It doesn't seem to do any harm but it's
untidy all the same.

Any suggestions?

Cheers,
Matthew.

Thanks heaps. That made things quiet once more.

While I was in there I noticed the stanza at the top which includes:

import pygtk
pygtk.require('2.0')

Can I suggest wrapping this with a check for py2exe? Like so:

if not hasattr(sys, 'frozen'):
     import pygtk
     pygtk.require('2.0')

This is because pygtk.require does not work with py2exe.

I guess this really a bug in pygtk. But since it is a show stopper at deployment time (as I discovered), I suggest it is important enough to provide this work around in matplotlib.

Cheers,
Matthew.

I changed the code in cvs to
import pygtk
if not hasattr(sys, 'frozen'):
    pygtk.require('2.0')

I think that should fix it.
