我正在使用python(我的版本是2.7)。我想将图像添加到GUI(Tkinter),然后使用pyinstaller转换为可执行格式。
我遵循了SO上的要求,也遵循了ActiveState上的要求

当我在代码中提及图片的路径时,仅当我直接运行它时它才起作用。如果我将其转换为exe,它将无法打开。

如其他解决方案所述更改代码,例如通过将其转换为编码的字符串,它可以在linux上正常运行。但是在Windows上会引发错误

码:

from Tkinter import *
from PIL import ImageTk, Image

logo = '''
----- encoded string -----
'''

root = Tk()
logoimage = Tkinter.PhotoImage(master=root, data=logo)
Label(root, image=logoimage).pack()
root.mainloop()


变更1:
上面的代码在Linux上有效。在Windows上,我在logoimage = Tkinter.PhotoImage(master=root, data=logo)行上收到错误

NameError: name 'Tkinter' is not defined


变更2:
所以我尝试将行更改为logoimage = ImageTk.PhotoImage(master=root, data=logo)。我得到的错误是

File "C:\Python27\lib\site-packages\PIL\ImageTk.py", line 88, in __init__
    image = Image.open(BytesIO(kw["data"]))
  File "C:\Python27\lib\site-packages\PIL\Image.py", line 2330, in open
    % (filename if filename else fp))
IOError: cannot identify image file <_io.BytesIO object at 0x00000000024BB150>
Exception AttributeError: "'PhotoImage' object has no attribute '_PhotoImage__photo'" in <bound method PhotoImage.__del__ of <PIL.ImageTk.PhotoImage object at 0x00000000024D49E8>> ignored


变更3:
但是,如果我将行更改为iconImage= ImageTk.PhotoImage(Image.open('path_to_image.png'))。仅当我直接运行时它才有效。如果我将其转换为可执行文件,则控制台将打开2-3秒,并显示诸如Unable to locate the image file之类的错误

最佳答案

显式地进行解码和转换可能比您当前正在执行的功能更强大。此代码在Linux上的Python 2.6.6上有效。

import io, base64
from Tkinter import *
from PIL import ImageTk, Image

#A simple 64x64 PNG fading from orange in the top left corner
# to red in the bottom right, encoded in base64
logo_b64 = '''

'''

#Decode the PNG data & "wrap" it into a file-like object
fh = io.BytesIO(base64.b64decode(logo_b64))

#Create a PIL image from the PNG data
img = Image.open(fh, mode='r')

#We must open the window before calling ImageTk.PhotoImage
root = Tk()

photo = ImageTk.PhotoImage(image=img)
Label(root, image=photo).pack()
Label(root, text='An embedded\nbase64-encoded PNG').pack()
root.mainloop()


供参考,这是嵌入式PNG的外观。
