问题描述
我正在尝试在Python中将背景图像添加到画布.到目前为止，代码如下:
I'm trying to add a background image to a canvas in Python. So far the code looks like this:
from Tkinter import *
from PIL import ImageTk,Image
... other stuffs
root=Tk()
canvasWidth=600
canvasHeight=400
self.canvas=Canvas(root,width=canvasWidth,height=canvasHeight)
backgroundImage=root.PhotoImage("D:\Documents\Background.png")
backgroundLabel=root.Label(parent,image=backgroundImage)
backgroundLabel.place(x=0,y=0,relWidth=1,relHeight=1)
self.canvas.pack()
root.mainloop()
它正在返回AttributeError:PhotoImage
It's returning an AttributeError: PhotoImage
推荐答案
PhotoImage 是不是Tk()实例(root)的属性.这是来自Tkinter的类.
PhotoImage is not an attribute of the Tk() instances (root). It is a class from Tkinter.
因此，您必须使用:
backgroundImage = PhotoImage("D:\Documents\Background.gif")
当心Label也是Tkinter ...
不幸的是，Tkinter.PhotoImage仅适用于gif文件(和PPM).如果需要读取png文件，则可以使用PIL中ImageTk模块中的PhotoImage(是，同名)类.
Unfortunately, Tkinter.PhotoImage only works with gif files (and PPM).If you need to read png files you can use the PhotoImage (yes, same name) class in the ImageTk module from PIL.
这样，这会将您的png图像放置在画布中:
So that, this will put your png image in the canvas:
from Tkinter import *
from PIL import ImageTk
canvas = Canvas(width = 200, height = 200, bg = 'blue')
canvas.pack(expand = YES, fill = BOTH)
image = ImageTk.PhotoImage(file = "C:/Python27/programas/zimages/gato.png")
canvas.create_image(10, 10, image = image, anchor = NW)
mainloop()
