How to change the image viewer in Python

Up to now, when I read and show an image in Python:

from scipy import misc
img = misc.imread("myimage.png")
misc.imshow(img)

it opens it by using ImageMagick.

How could I change the reader from ImageMagick to, say, Image Viewer? I guess I should change the Python environment, but I do not have any further clue.

Solution

  • The docstring for misc.imshow says

    In [10]: misc.imshow?
Signature: misc.imshow(arr)
Docstring:
Simple showing of an image through an external viewer.

Uses the image viewer specified by the environment variable
SCIPY_PIL_IMAGE_VIEWER, or if that is not defined then `see`,
to view a temporary file generated from array data.

    Therefore, set the SCIPY_PIL_IMAGE_VIEWER environment variable to the path of your eog (Image Viewer) executable.
