ImageTk Paste

I'm back again with my camera app! Trying to overlay/merge two images when saving them.
The error i get is

Error:
AttributeError: 'PhotoImage' object has no attribute 'load'

Please see code below:

There is no load in your code, and you haven't included the entire traceback (which would show where the error is being produced). Is this all the code?

[Yoriz]

Hello again, I don't see load used directly anywhere it must be called indirectly.
You should show the full error traceback as it indicates where it went wrong and more information.

Hello again, I don't see load used directly anywhere it must be called indirectly.

It's in ImageTk.py:

I think due to Namespace flooding with * imports you've learnt your lesson in why to not do it.

The code is expecting a PIL Image instead I think its got a tkinter Image which has no load method see the tk Image class below.

Try removing from tkinter import * and using import tkinter as tk from now on.

Hi Yoriz!
I tried the above and subsequently had to add tk. before various objects such as

1

Canvas

and

1

Button

Still getting the same error:

Error:

O I thought that was going to fix it but it's good that you got rid of the * imports

1	self.overlay_img = ImageTk.PhotoImage(file=file)

self.overlay_img is a Tkinter-compatible photo image

---

1	self.photo = ImageTk.PhotoImage(image=Image.fromarray(frame))

self.photo is also a Tkinter-compatible photo image

---

When calling paste I think the passed in image has to be an actual PIL image.

1	self.photo.paste(self.overlay_img, (0, 0))

---

as self.overlay_img is used in the update method You probably need to keep self.overlay_img as it is

1 2 3 4 5 6

def update(self):     ...     ...     if self.overlay_img:         #self.canvas.tag_raise(self.overlay_img)         self.canvas.create_image(0,0, image=self.overlay_img, anchor=NW)

---

Here is what I hope will fix it

When you make self.overlay_img try also making a pill image

1 2 3 4 5 6

def overlay(self):     file = filedialog.askopenfile(         mode='rb', defaultextension='.png',title="Choose Overlay Image", filetypes=[("PNG Files", '*.png')])     if file:         self.overlay_img = ImageTk.PhotoImage(file=file)         self.pil_overlay_img = Image.open(file)

Then change

1 2	if isTrue and self.overlay_img:     self.photo.paste(self.overlay_img, (0, 0))

to

1 2	if isTrue and self.pil_overlay_img:     self.photo.paste(self.pil_overlay_img, (0, 0))

This is from the documentation for PIL ImageTk module.

https://pillow.readthedocs.io/en/stable/...ageTk.html

paste(im, box=None)[source]
Paste a PIL image into the photo image. Note that this can be very slow if the photo image is displayed.

Parameters
im – A PIL image. The size must match the target region. If the mode does not match, the image is converted to the mode of the bitmap image.

box – A 4-tuple defining the left, upper, right, and lower pixel coordinate. See Coordinate System. If None is given instead of a tuple, all of the image is assumed.

Notice that im is a PIL image, not an ImageTk.PhotoImage. You need to load your overlay using

PIL.Image.open(fp, mode='r', formats=None)

Lesson learned on imports

Unfortunately neither of the above work. I don't get an error but the image saves without the overlay on it.

[Yoriz]

The error is gone, that's progress
Try it with both images being pillow images
Paste another image into an image with Python, Pillow
