详解详解python tkinter 图片插入问题图片插入问题
通过tkinter.PhotoImage插入GIF, PGM/PPM格式的图片。
import tkinter
class Gui:
def __init__(self):
self.gui=tkinter.Tk() # create gui window
self.gui.title("Image Display") # set the title of gui
self.gui.geometry("800x600") # set the window size of gui
img = tkinter.PhotoImage(file="C:/Users/15025/Desktop/bear.gif") # read image from path
label1=tkinter.Label(self.gui,image=img) # create a label to insert this image
label1.grid() # set the label in the main window
self.gui.mainloop() # start mainloop
main = Gui()
注意: img = tkinter.PhotoImage(file=”C:/Users/15025/Desktop/bear.gif”) 中的关键字file不能够省略,否则程序无法正常显示
图片。
对于常用的PNG,与JPG格式的图片,我们需要从python image library(pillow)(PIL)导入Image与ImageTk模块来实现,代码
如下:
import tkinter
from PIL import Image
from PIL import ImageTk
class Gui:
def __init__(self):
self.gui=tkinter.Tk() # create gui window
self.gui.title("Image Display") # set the title of gui
self.gui.geometry("800x600") # set the window size of gui
load = Image.open("C:/Users/15025/Desktop/1.png") # open image from path
img = ImageTk.PhotoImage(load) # read opened image
label1=tkinter.Label(self.gui,image=img) # create a label to insert this image
label1.grid() # set the label in the main window
self.gui.mainloop() # start mainloop
main = Gui()
然而在实际操作中,本人使用的是Anaconda spyder编译器,当我们在读入图像时程序出错后,再次运行程序就会导致image
“pyimage1” doesn’t exist错误,每次运行一次,数字就会增加1,如:image “pyimage2” doesn’t exist。遇到此错误,可以直
接在IPython控制台界面重启IPython内核即可,或者关闭编译器并重新打开。
看似我们已经完全实现了图片的插入,但是这种插入方法是存在隐患的,具体代码如下:
import tkinter as tk
from PIL import Image
from PIL import ImageTk
class Gui(tk.Tk):
def __init__(self):
super().__init__()
self.title("Figure dynamic show v1.01")
# self.geometry("1000x800+400+100")
self.mainGui()
# self.mainloop()
def mainGui(self):
image = Image.open("C:/Users/15025/Desktop/1.png")
photo = ImageTk.PhotoImage(image)
label = tk.Label(self, image=photo)
