Hi all I have to do a little script in Python. In this script I have a variable (that represents a coordinate) that is continuously updated to a new value. So I have to draw a red point over a image and update the point position every time the variable that contains the coordinate is updated.
I tried to explain what I need doing something like this but obviously it doesn't works:
import Tkinter, Image, ImageDraw, ImageTk
i=0
root = Tkinter.Tk()
im = Image.open("img.jpg")
root.geometry("%dx%d" % (im.size[0], im.size[1]))
while True:
draw = ImageDraw.Draw(im)
draw.ellipse((i, 0, 10, 10), fill=(255, 0, 0))
pi = ImageTk.PhotoImage(im)
label = Tkinter.Label(root, image=pi)
label.place(x=0, y=0, width=im.size[0], height=im.size[1])
i+=1
del draw
someone may help me please? thanks very much!
