I can't seem to get my PIL Image to work on canvas. Code:
from Tkinter import*
import Image, ImageTk
root = Tk()
root.geometry('1000x1000')
canvas = Canvas(root,width=999,height=999)
canvas.pack()
image = ImageTk.PhotoImage("ball.gif")
imagesprite = canvas.create_image(400,400,image=image)
root.mainloop()
Error:
Traceback (most recent call last):
File "C:/Users/Mark Malkin/Desktop/3d Graphics Testing/afdds.py", line 7, in <module>
image = ImageTk.PhotoImage("ball.gif")
File "C:\Python27\lib\site-packages\PIL\ImageTk.py", line 109, in __init__
mode = Image.getmodebase(mode)
File "C:\Python27\lib\site-packages\PIL\Image.py", line 245, in getmodebase
return ImageMode.getmode(mode).basemode
File "C:\Python27\lib\site-packages\PIL\ImageMode.py", line 50, in getmode
return _modes[mode]
KeyError: 'ball.gif'
I need to use PIL images not PhotoImages because I want to resize my images. Please don't suggest switching to Pygame because I want to use Tkinter.
Try creating a PIL Image first, then using that to create the PhotoImage.
from Tkinter import *
import Image, ImageTk
root = Tk()
root.geometry('1000x1000')
canvas = Canvas(root,width=999,height=999)
canvas.pack()
pilImage = Image.open("ball.gif")
image = ImageTk.PhotoImage(pilImage)
imagesprite = canvas.create_image(400,400,image=image)
root.mainloop()
(An old question, but the answers so far are only half-complete.)
Read the docs:
class PIL.ImageTk.PhotoImage(image=None, size=None, **kw)
image
– Either a PIL image, or a mode string. [...]
file
– A filename to load the image from (using Image.open(file)
).
So in your example, use
image = ImageTk.PhotoImage(file="ball.gif")
or explicitly
image = ImageTk.PhotoImage(Image("ball.gif"))
(And remember – as you did correctly: Keep a reference to the image object in your Python program, otherwise it is garbage-collected before you seee it.)
You can import multiple image formats, and resize with this code. "basewidth" sets the width of your image.
from Tkinter import *
import PIL
from PIL import ImageTk, Image
root=Tk()
image = Image.open("/path/to/your/image.jpg")
canvas=Canvas(root, height=200, width=200)
basewidth = 150
wpercent = (basewidth / float(image.size[0]))
hsize = int((float(image.size[1]) * float(wpercent)))
image = image.resize((basewidth, hsize), PIL.Image.ANTIALIAS)
photo = ImageTk.PhotoImage(image)
item4 = canvas.create_image(100, 80, image=photo)
canvas.pack(side = TOP, expand=True, fill=BOTH)
root.mainloop()
