can someone help me take a screnshot of a specific frame?
been playing with these, but cant seem to specify just the frame
import pyautogui
#im1 = pyautogui.screenshot()
#im1.save('my_screenshot.png')
#im2 = pyautogui.screenshot('my_screenshot2.png')
from tkinter import *
import time
from PIL import ImageTk, Image
import pyautogui as pg
# Create an instance of tkinter frame or window
win = Tk()
# Set the size of the window
win.geometry("700x350")
frm2shoot = Frame(win)
frm2shoot.grid(column=0, row=0)
lbl = Label(frm2shoot, width=16, text="testing testing:", justify=LEFT, anchor="w").grid(row=0, column=0, sticky=W, pady=2)
# Define a function for taking screenshot
def screenshot():
random = int(time.time())
filename = "/Users/ricardosimoes/Desktop/"+ str(random) + ".jpg"
ss = pg.screenshot(filename)
ss.show()
frm2shoot.deiconify()
# Create a Button to take the screenshots
button = Button(win, text="Take Screenshot", font=('Aerial 11 bold'), background="#aa7bb1", foreground="white", command=screenshot)
button.grid(column=5, row=0)
win.mainloop()
Anyone have any idea how to do this??

I wonder if it's possible to insert an image or icon in the title of a Labelframe in tkinter ?
Maybe something like this lf = Labelframe(root, image='my_img'), the same as we can do with a button.
It would be very useful.
You can insert any widget as labelwidget option of LabelFrame.
If you want an image instead of text displayed in LabelFrame:
import tkinter as tk
from PIL import Image, ImageTk
w = tk.Tk()
w.geometry("400x500")
img_open = Image.open("example_1.png")
img = ImageTk.PhotoImage(img_open)
label_title = tk.Label(w, image=img) #important Do Not grid/pack/place it!
label_frame = tk.LabelFrame(w, labelwidget=label_title)
label_frame.grid(row=0, column=0)
#fill LabelFrame with something to make it visible
bt = tk.Button(label_frame, text="Press")
bt.grid(padx=20, pady=20)
w.mainloop()
Output:
Or like I said before you can use any widget.
An example label with image and a label with text.
import tkinter as tk
from PIL import Image, ImageTk
w = tk.Tk()
w.geometry("400x500")
img_open = Image.open("example_1.png")
img = ImageTk.PhotoImage(img_open)
frame_labelwidget = tk.Frame(w) #important Do Not grid/pack/place it!
label_image = tk.Label(frame_labelwidget, image=img)
label_image.grid(row=0, column=0)
label_text = tk.Label(frame_labelwidget, text="Teamwork")
label_text.grid(row=0, column=1)
label_frame = tk.LabelFrame(w, labelwidget=frame_labelwidget)
label_frame.grid(row=0, column=0)
#fill LabelFrame with something to make it visible
bt = tk.Button(label_frame, text="Press")
bt.grid(padx=20, pady=20)
w.mainloop()
Output:
Of course that makes less sense because you can have text and an image combined in tk.Label by using compound option.
I added it only for demonstration purpose, you can add any widget you want. Instead of label_text you could add an Entry, Canvas...
having problems displaying an image using treeview. Found some other mentions on the net with a similar problem but the answers do not seem to work for me. I am using Win10 if that makes a difference
import ttkthemes
import tkinter as tk
from tkinter import ttk
from tkinter.messagebox import showinfo
from tkinter import PhotoImage
from PIL import Image, ImageTk
self = tk.Tk()
self.title('Tkinter PhotoImage Demo')
#self.image = Image.open("A4.bmp")
#self.python_image = ImageTk.PhotoImage(self.image)
#print(self.python_image)
#ttk.Label(self, image=self.python_image).pack()
# columns
columns = ('#1', '#2')
tree = ttk.Treeview(self, columns=columns, show='headings', height=20)
tree.tag_configure('oddrow', background='#ece0cf')
tree.tag_configure('evenrow', background='#e0e0e0')
style = ttk.Style()
style.theme_use('clam')
style.configure("Treeview",font=(None,12))
style.configure("Treeview.Heading", font=(None, 12))
# define headings
tree.heading('#1', text='Date')
tree.column("#1", minwidth=0, width=160)
tree.heading('#2', text='Logo')
tree.column("#2", minwidth=0, width=80)
# add a scrollbar
scrollbar = ttk.Scrollbar(self, orient=tk.VERTICAL, command=tree.yview)
tree.configure(yscroll=scrollbar.set)
scrollbar.grid(row=0, column=1, sticky='ns')
tree.grid(row=0, column=0, sticky='nsew')
logo="A4.bmp"
rowcol='oddrow'
im = Image.open(logo)
ph = ImageTk.PhotoImage(im)
print(ph)
tree.insert('', -1, values=("2021-03-25", logo), image=ph, tags=(rowcol,))
tree.grid(row=0, column=0, sticky='nsew')
self.update_idletasks()
self.update()
If it helps the value of ph is: pyimage1
The commented out code at the start displays the image just fine, so the issue seems to be on adding the image itself into the tree.insert.... bit of coding
Whilst I have your attention and as related but very minor questions, is there also a way to add a second image into treeview? Plus is there a way to display some values, then an image, then some more values, then another image and finally more values, or do the images have to be at the start or end of the rows?
The below code displays video on the label. But, problem is that, it is displayed in a very zoom (large) manner. I want to resize it to display correctly on label. When I use the option image=image.resize(), I get an error
ValueError: cannot resize this array: it does not own its data
import tkinter as tk, threading
import imageio
from PIL import Image, ImageTk
video_name = "e.mp4"
video = imageio.get_reader(video_name)
#video = video.resize(20,20)
def stream(label):
for image in video.iter_data():
frame_image = ImageTk.PhotoImage(Image.fromarray(image))
label.config(image=frame_image)
label.image = frame_image
root = tk.Tk()
my_label = tk.Label(root, width=500,height=500)
my_label.place(x=0,y=0)
thread = threading.Thread(target=stream, args=(my_label,))
thread.daemon = 1
thread.start()
root.mainloop()
You can call resize() on the return image of Image.fromarray(image):
frame_image = ImageTk.PhotoImage(Image.fromarray(image).resize((100,100)))
I can't add image (gif image) to tkinter window.
from tkinter import *
from tkinter import filedialog
from PIL import ImageTk, Image
root = Tk()
def open_image():
qr_select = filedialog.askopenfilename(title = "open")
im = PhotoImage(file=qr_select)
w1 = Label(window, image = im)
w1.image = im
w1.config(image=im)
w1.pack(side="right")
def window_function():
global window
window=Tk()
window.geometry("800x550+650+250")
window.title("QR_Scanner")
btn = Button(window,text = "open a gif picture",command = open_image)
btn.pack()
root.iconify()
window.mainloop()
btn = Button(root,text = "open window",command = window_function)
btn.pack()
root.mainloop()
my error is (_tkinter.TclError: image "pyimage1" doesn't exist)
The reason you can't see your gif in the window is that you haven't made a reference to the image so it is collected in Tkinters garbage collector. Read More About This Here. To Add a reference to the image you can do this:
w1.image = im
And add it in your code here:
def open_image():
qr_select = filedialog.askopenfilename(title = "open")
im = PhotoImage(file=qr_select)
w1 = Label(root, image = im)
w1.image = im #Keep A Reference To The Image
w1.config(image=im)
w1.pack(side="right")
The reason you are getting pyimage1 doesn't exist is because you have more than one instance the Tk and there is only meant to be 1. You have to make your window a Toplevel() by replacing: window=Tk() with window=TopLevel()
I am trying to make a simple play/pause application in tkinter. Basically I want to show a video and have a play/pause button underneath.
So, after some research I found this suitable post to show a video using tkinter and opencv:
to show video streaming inside frame in tkinter
When using the code, given in the accepted answer to show a video, there is no problem and I don't see any flickering. Here is the code:
# import the necessary packages
from __future__ import print_function
import tkinter as tk
from PIL import ImageTk, Image
import cv2
root = tk.Tk()
# Create a frame
app = tk.Frame(root, bg="white")
app.grid()
# Create a label in the frame
lmain = tk.Label(app)
lmain.grid()
# Capture from camera
cap = cv2.VideoCapture(r'PATH_TO_VIDEO_FILE')
# function for video streaming
frame_number = 0
def video_stream():
global frame_number
cap.set(cv2.CAP_PROP_POS_FRAMES, frame_number)
success, frame = cap.read()
cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
img = Image.fromarray(cv2image)
imgtk = ImageTk.PhotoImage(image=img)
lmain.imgtk = imgtk
lmain.configure(image=imgtk)
lmain.after(1, video_stream)
frame_number += 1
video_stream()
root.mainloop()
Now, I slightly altered the code to be able to use the grid manager and add a play button:
# import the necessary packages
from __future__ import print_function
import tkinter as tk
from PIL import ImageTk, Image
import cv2
class PhotoBoothApp:
def __init__(self, path_to_video):
# initialize the root window
self.window = tk.Tk()
self.window.title("Video_Player")
self.videocap = cv2.VideoCapture(path_to_video)
self.frame_number = 0
# Initalize
self.videocap.set(cv2.CAP_PROP_POS_FRAMES, self.frame_number)
success, self.frame = self.videocap.read()
cv2image = cv2.cvtColor(self.frame, cv2.COLOR_BGR2RGBA)
self.img = Image.fromarray(cv2image)
self.imgtk = ImageTk.PhotoImage(image=self.img)
# Show frames
self.picture_label = tk.Label(self.window, image=self.imgtk, relief=tk.RIDGE).grid(row=0, column=0)
self.btn_next_image=tk.Button(self.window, text="Play", width=50, bg ="green",command=self.video_stream).grid(row=1,column=0)
self.window.mainloop()
def video_stream(self):
self.videocap.set(cv2.CAP_PROP_POS_FRAMES, self.frame_number)
sucess, frame = self.videocap.read()
cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
img = Image.fromarray(cv2image)
self.imgtk = ImageTk.PhotoImage(image=img)
self.picture_label = tk.Label(self.window, image=self.imgtk, relief=tk.RIDGE).grid(row=0, column=0)
# Update Frame Number to display
self.frame_number = self.frame_number + 1
self.window.after(1, self.video_stream)
ph = PhotoBoothApp(r'PATH_TO_FILE')
The problem is that when I execute the above code, the video flickers as if tkinter need to reload something in-between frames. I have no clue why this happens.
P.S. This post here Flickering video in opencv-tkinter integration did not help me.
You need to make two changes: split your self.picture_label line to create a proper reference to your Label object, and then use self.picure_label.config(...) to change the image.
class PhotoBoothApp:
def __init__(self, path_to_video):
# initialize the root window
...
self.picture_label = tk.Label(self.window, image=self.imgtk, relief=tk.RIDGE)
self.picture_label.grid(row=0, column=0)
...
def video_stream(self):
...
img = Image.fromarray(cv2image)
self.imgtk = ImageTk.PhotoImage(image=img)
self.picture_label.config(image=self.imgtk)
# Update Frame Number to display
self.frame_number = self.frame_number + 1
self.window.after(1, self.video_stream)
ph = PhotoBoothApp(r'PATH_TO_FILE')
