Hi Vasilis,
sorry for the belated reply.
This is tricky, I tried several suggestions found in the web to no avail.
Finally for once an AI engine proved useful and provided me with an
almost working solution which it seems I could fix with a little
try-and-error :-)
Here's the fixed AI code example:
##########################################
import tkinter as tk
from PIL import Image, ImageTk
import io
root = tk.Tk()
root.geometry("700x500")
root.title("Copy a Picture from Tkinter Canvas to Clipboard")
canvas = tk.Canvas(root, width=400, height=400)
canvas.pack()
image = Image.open("image.jpg")
image_tk = ImageTk.PhotoImage(image)
canvas.create_image(0, 0, anchor="nw", image=image_tk)
def copy_image_to_clipboard():
# Retrieve the image from the canvas
canvas_image = canvas.postscript()
# Create an in-memory file-like object
image_buffer = io.BytesIO()
# Save the canvas image to the buffer in PNG format
image = Image.open(io.BytesIO(canvas_image.encode('utf-8')))
image.save(image_buffer, format="PNG")
image_buffer.seek(0)
# Copy the image to the clipboard
root.clipboard_clear()
root.clipboard_append(image_buffer.getvalue(), type="image/png")
copy_button = tk.Button(root, text="Copy Image",
command=copy_image_to_clipboard) copy_button.pack()
root.mainloop()
##########################################
The trick is apparently to change format="image/png" (suggested by our
artificial friend) to type="image/png" in clipboard_append(). With
format="image/png" when trying to paste the clipboard into lowriter I got
only a mess of characters.
Have a nice day,
Michael
