如何在画布上的Tkinter中打开PIL图像

use*_*814 8 python tkinter python-imaging-library tkinter-canvas

我似乎无法让我的PIL Image在画布上工作.码:

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()

错误:

我需要使用PIL图像而不是PhotoImages,因为我想调整图像的大小.请不要建议切换到Pygame,因为我想使用Tkinter.

首先尝试创建PIL图像,然后使用它创建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()

您可以导入多种图像格式,并使用此代码调整大小。“basewidth”设置图像的宽度。

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()

(一个老问题,但到目前为止答案仅是一半。)

阅读文档:

class PIL.ImageTk.PhotoImage(image=None, size=None, **kw)

  • image– PIL图像或模式字符串。[...]
  • file–从中加载图像的文件名(使用Image.open(file))。

因此,在您的示例中,使用

image = ImageTk.PhotoImage(file="ball.gif")

或明确地

image = ImageTk.PhotoImage(Image("ball.gif"))

(请记住-正确无误:请在Python程序中保留对图像对象的引用,否则在您看到它之前将对其进行垃圾收集。)
