[Matplotlib-users] display each images from a directory

[Massimo Di S. <mas...@gm...>]

Hello All,

i'm tring to write python code to display images from a directory .. but i'm not able to learn how to use the matplotlib events
to handle how the images will be displaied.

simpli i need to pass to the code the path to directory where i have several tiff files and disply them one at time using a key event.

to display a single image i'm using somethin like :



#!/usr/bin/env python
from pylab import *
try:
    import Image
except ImportError, exc:
    raise SystemExit("PIL must be installed to run this example")
import glob

def dispimg(input):
    image = Image.open(input)
    im = imshow(image, origin='lower')
    show()



###########

i tried to define a key action like :


def onpress(event):
    if event.key=='a':
        fig.canvas.draw()


# and set my directory with :

fig = figure()
fig.canvas.mpl_connect('key_press_event', onpress)
TIFFS = glob.glob("/home/habcam/habcamdata/20100820_1840/*.tif")
print "num TIFFS %d" % len(TIFFS)

##############

but i'm not able to learn how to plot them and update the displayed image using the key bindings :

for tif in TIFFS:
    print tif
    show()


thanks a lot for Any help!


Massimo.
