我试图制作一张图片,但它无法正常工作,我不知道自己做错了什么。当我点击应该显示图像的按钮时,我得到的只是白色画布,没有图像。如何让它显示?
def show_original(self):
from os.path import exists
from PIL import Image, ImageTk
if not os.path.exists(self.wdg_orig_file_name_.get()):
tkMessageBox.showinfo('Load','File does not exist:' + self.wdg_orig_file_name_.get())
return
self.orig_image_=Image.open(str_orig_file_name)
canvas = self.gui_.ca(500,500,bg='white')
im_TK = ImageTk.PhotoImage(self.orig_image_)
canvas.create_image(250,250,image=im_TK)
canvas.pack()
pass
主循环中的 self.wdg_orig_file_name_.get()
是:
self.wdg_orig_file_name_ = self.gui_.en(text='boat.png')
全球str_orig_file_name
已在pick_file()
中分配:
def pick_file(self):
'''Opens a file dialog and sets its result to the filename entry'''
global str_orig_file_name
str_orig_file_name = tkFileDialog.askopenfilename()
if str_orig_file_name:
self.wdg_orig_file_name_.delete(0, END)
self.wdg_orig_file_name_.insert(0, str_orig_file_name)
#We got a new image to process. Forget the previous results.
self.orig_image_ = None
self.preview_image_ = None

你试过easygui吗?
#!/usr/bin/python
from easygui import *
image = "img.jpg"
msg = "Do you like this picture?"
choices = ["Yes","No","No opinion"]
reply=buttonbox(msg,image=image,choices=choices)
很简单。

对不起我虽然OP正在寻找一种显示图像的方法,现在我看到图像应该在按钮上。好吧,我试过这个,它与.gif和.png一起工作得很好。但是,.jpg会出错:“_ tkinter.TclError:无法识别图像文件中的数据”img.jpg“”。
#!/usr/bin/python
from Tkinter import *
root=Tk()
b=Button(root,justify = LEFT)
photo=PhotoImage(file="img.png")
b.config(image=photo,width="100",height="100")
b.pack(side=LEFT)
root.mainloop()
