Re: [Matplotlib-users] Is really matplotlib this slooow for displaying images ? (sorry again)

[Eric E. <ems...@ob...>]

Hi,
thanks for the feedback.

To answer your questions:

- I have both Numeric and numarry but I am using
numarray in principle.

- Running in verbose mode, here is the output:

matplotlib data path /usr/share/matplotlib
loaded rc file /home/emsellem/.matplotlibrc
matplotlib version 0.65
verbose.level helpful
interactive is False
platform is linux2
numerix numarray 1.0
font search path ['/usr/share/matplotlib']
loaded ttfcache file /home/emsellem/.ttffont.cache
Could not load matplotlib icon: 'module' object has no attribute 
'window_set_default_icon_from_file'
backend GTKAgg version 2.0.0

- Then a VERY important note: yes indeed I am an astronomer
and I am used to have a fixed window (I first define its size
or use some default) and THEN ONLY load the image itself.
This is how I use ppgplot in python or Iraf, or Midas.
I indeed to not then use any interpolation scheme there.

- ALSO: there seems to be a bug in the figimage routine as
  it shows the image OUTSIDE an axis filled with white
(this may be because I am not doing the right thing though...)

- And finally here are the timing you asked for:
(there seem to be reasonable considering the difference
in CPU/RAM)

Hope this helps

Eric
