I get a NameError on the very first line.
>>> urllib.urlretrieve(findu, "image.png")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'urllib' is not defined
When you want to demonstrate a problem try to make a self-contained example,
i. e. one that can be run without the need for us guess the surrounding
code. Remove everything that is irrelevant for the problem like the logging
in code below and the png/gif conversion gymnastics.
Anyway, here is a self-contained demo (you have to pass the filename of an
image on the commandline):
import Tkinter
import ImageTk
import Image
import sys
[filename] = sys.argv[1:]
image = Image.open(filename)
root = Tkinter.Tk()
frame = Tkinter.Frame(root)
frame.pack()
label = Tkinter.Label(root)
label.pack()
def make_resize(percent):
def resize():
width, height = image.size
label.image = label["image"] = ImageTk.PhotoImage(
image=image.resize((width*percent//100, height*percent//100)))
return resize
make_resize(100)()
pairs = [
("Small", 20),
("Medium", 50),
("Original", 100),
("Big", 200)]
for i, (text, percent) in enumerate(pairs):
button = Tkinter.Button(frame, text=text, command=make_resize(percent))
button.grid(row=0, column=i)
root.mainloop()
