This is a basic script that should insert a watermark image on the first page of a PDF and save it under a new name.
I could do the same with the same files in pdfrw, but I'm stuck with PyMuPDF (which I would prefer to use...).
The py file is in the same folder with the pdf and the png.
import fitz
input_file = "sample.pdf"
output_file = "sample_stamped.pdf"
stamp = "watermark.png"
doc = fitz.open(input_file)
rect = fitz.Rect(0, 0, 100, 100)
pix = fitz.Pixmap(stamp)
page = doc[0]
page.insertImage(rect, pixmap = pix, overlay = True)
doc.save(output_file)
I'm getting this error msg:
Traceback (most recent call last):
File "D:/Google Drive/Python/PDF/pdfstamp.py", line 14, in <module>
doc.save(output_file)
File "D:\Python\lib\site-packages\fitz\fitz.py", line 2411, in save
return _fitz.Document_save(self, filename, garbage, clean, deflate, incremental, ascii, expand, linear, pretty, decrypt)
RuntimeError: not a dict (array)
Thanks in advance for any help.

Any frequent help will be much appreciated
A wand.image.Image object is not a valid argument for Shapes.add_picture(). The first argument to that call needs to be the str path to an image file or a file-like object containing an image.
I suppose that means you'll need to save the modified image as a JPG or PNG or whatever and then provide the filename. You could also save it to a BytesIO object and pass that to .add_picture() as that would count as a file-like object and not require using the filesystem.
I'm working on GCP cloud functions and intend to write a functions which combines two images. But I', getting the following error when I invoke the function:
Traceback (most recent call last): File

PIL.UnidentifiedImageError: cannot identify image file '/tmp/logo.jpg'
I have ran this function on my local machine and it works as expected but when I deploy it on GCP, it gives this error and crashes. Here's my function:
from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw
def generateIntroImage(stdName, stdPicture, logo, year, typeFace):
images = [Image.open(x) for x in [stdPicture, logo]]
widths, heights = zip(*(i.size for i in images))
total_width = sum(widths)
max_height = max(heights)
new_im = Image.new('RGB', (total_width, max_height))
x_offset = 0
for im in images:
new_im.paste(im, (x_offset,0))
x_offset += im.size[0]
font= ImageFont.truetype(typeFace, 70)
draw= ImageDraw.Draw(new_im)
draw.text((0, 0), stdName+"'s " +year+" Year Book", (0,0,0),font= font)
fileName= "/tmp/test.jpg"
new_im.save(fileName)
return fileName
These images are .jpg and .png files. Any idea what could be wrong?
Happened to me on Google Colab as well, apparently updating PIL version fixed the problem for me.
PIL throws error because it cannot identify the image format. Most probably the reason is that the image is corrupted and hence cannot be read (or "identified") by pillow's Image.open(). For example if you try opening the image in an IPython prompt, it would fail as well.
In [2]: from PIL import Image
In [3]: Image.open("176678612.jpg")

"""

raise UnidentifiedImageError(

So, the fix is to delete the image, or replace it with an uncorrupted version.
you need to provide a downloadable link to the image. What worked for me was click on the download image and the copy that URL.
So, I need to resize an image in tkinter. Before you do anything - this is not a duplicate. I have gone through every other question on this site and none have helped me. The thing with me is - I don't wan't to save the image. I need to load the image, resize it, then display it with PhotoImage in a label. I tried to use ImageTk, but for some reason it won't work.
Here's my code with ImageTk:
from tkinter import *
import PIL
from PIL import Image, ImageTk
root = Tk()
left_nose_path_white = Image.open(r'C:\Users\User\Documents\Python stuff\Other apps\Veteris\Dog photos\Advanced\Sides\GIF\Nose\Nose (left) - White.gif')
def resize_image():
global left_nose_path_white
total_screen_width = root.winfo_screenwidth()
total_screen_height = root.winfo_screenheight()
frame_width, frame_height = left_nose_path_white.size
dog_new_width = int(frame_width / 3)
dog_new_height = int(frame_height / 3)
left_nose_path_white = left_nose_path_white.resize((dog_new_width, dog_new_height), Image.LANCZOS)
resize_image()
left_nose_img_white = ImageTk.PhotoImage(file = left_nose_path_white)
label = Label(image = left_nose_img_white)
label.pack()
root.mainloop()
This returns the error:
File "C:\Users\User\AppData\Local\Programs\Python\Python37\lib\site-packages\PIL\ImageTk.py", line 124, in __del__
name = self.__photo.name
AttributeError: 'PhotoImage' object has no attribute '_PhotoImage__photo'
My code should find the width and height of the original image, divide it by 3, and then show it. The reason I don't want to have to save the image is because the user will open the application several times.
I'm new to using PILL/Pillow, so the answer may be obvious.
I have Pillow installed using pip.
I only have one version of Python on my computer (Python 3.7)

I am making a simple OpenGL 3.3 OBJ viewer in Python using the modules Pyglet and Ratcave. I want to load a textured sphere I made in Blender. While my Pyglet/Ratcave OBJ viewer loads untextured OBJ files, when I add textures to my project, I get this error and the program fails to load:
ValueError: could not convert string to float: 'textures'
What does this mean?
I got a different error when I tried to import textures from my OneDrive folder and use them in my Blender project. When I put the textures in the same folder as the script and OBJ/MTL files, it got rid of that error, but now I can't load the textures because, for whatever reason, Ratcave needs to convert the textures to a float and it can't do that.
import pyglet
import ratcave as rc
import time
window = pyglet.window.Window()
def update(dt):
pass
pyglet.clock.schedule(update)
# Insert filename into WavefrontReader
obj_filename = 'Textured Sphere Eevee.obj'
obj_reader = rc.WavefrontReader(obj_filename)
# Check which meshes can be found inside the Wavefront file, and extract it into a Mesh object for rendering
print(obj_reader.bodies.keys())
Sphere = obj_reader.get_mesh("Cube")
Sphere.position.xyz = 0, 0, -10
scene= rc.Scene(meshes=[Sphere])
#window.event
def on_draw():
with rc.default_shader:
scene.draw()
#scene.clear()

pyglet.app.run()

When I run my program, I get the following error and am not sure on how to correct it. Can someone help with explaining what this error is and how to correct it? Newb here so details are appreciated. Thanks for your time in advance!

In your file and target directory code blocks, dialog.selectedFiles() returns a list. zipfile.ZipFile can only handle one file at a time, hence your error. To iterate over the list being provided by dialog.selectedFiles(), use the following:
for archive in fileName: # you should probably change it to fileNames to reflect its true nature
zfile = zipfile.ZipFile(archive)
print("Extracting " + str(zfile.filename) + "...")
zfile.extractall(dirName[0]) # also a list, extract to first item and ignore rest
and you should be all set.
