Below is en2.py code-
# The Python Imaging Library
# $Id$
# this demo script creates four windows containing an image and a slider.
# drag the slider to modify the image.
#
from Tkinter import *
from PIL import Image, ImageTk, ImageEnhance
import sys
# enhancer widget
class Enhance(Frame):
def __init__(self, master, name, enhancer, lo, hi):
Frame.__init__(self, master)
# set up the image
self.tkim = ImageTk.PhotoImage(image.mode, image.size)
self.enhancer = enhancer(image)
#mid = (lo + hi)/2
self.update('1.0') # normalize
# image window
Label(self, image=self.tkim).grid()
# scale
s = Scale(self, label=name, orient=HORIZONTAL,
from_=lo, to=hi, resolution=0.01,
command=self.update)
#if image == "ip_img.jpg" or image == "not_img.jpg":
# s.config(state=DISABLED)
s.set(self.value)
s.grid(row=0,column=0)
def update(self, value):
self.value = eval(value)
tkim.paste(self.enhancer.enhance(self.value))
Now in another code below, I have to write the code that resizes en2.image or another ImageTk.PhotoImage instance that contains a copy of en2.image.
####zoom in photoimage instance of en2.image code here
Label(top, image=en2.tkim).grid(row=0, column=10, columnspan=20, rowspan=20,padx=10, sticky=W+E+N+S)
im = Image.open("zoomin.jpg")
image = im.resize((80,30),Image.ANTIALIAS)
photo = ImageTk.PhotoImage(image)
b=Button(root, image=photo,command=zoomin)
b.grid(row=5,column=0)root.mainloop()
I've googled and some documents show that there is a zoom method that can be used with photoimage instance but it gives attribute error on the interpreter.
I tried to change the height and width explicitly using en2.image.height=900 (say), but even thats not working, it does not raise an error, but at the same time, it does not alter the height.
Please tell me a way so that I can resize en2.image.
