displaying pgm file in python

[wilson]

i converted an 8bit rgb .jpg file into .pgm using adobe photoshop and
a plugin from http://photoshop.pluginsworld.com/pl...-exporter.html
I want to check if this file can be properly displayed.
Image opening and show() in PIL fails to do it so i tried Tkinter

i created a canvas in a tkinter gui and tried
self.myimg=Phot oImage(file="my testpic.pgm")

self.selimgtag= self.canvorig.c reate_image(70, 100,image=self. myimg)
self.canvorig.u pdate_idletasks ()

this causes AttributeError snd says can't identify image file
I checked the asci text of .pgm file ,it starts with a line P2 and
then several lines with integers..can someone tell me if there is a
way to display this properly

thanks

P2 is a rather old variant that it's not in use anymore AFAIK. Try
replacing P2 with P5; at least PIL should recognize it, I think. PIL can
read and write .pgm, why don't you do the conversion with PIL?
