问题 I am trying to read the Exif data from a downloaded image. I save the image to my computer in one function then try to read the data in another function, but I keep getting a bad mode error. I have been able to read the data from a pre saved image and just used ._getexif() but when I try to do the same thing with the image I download it does not work. What am I doing wrong? Here is the loop that calls the two functions. else: imgTags = findImages(url) for imgTag in imgTags: imgFileName =

Code: image = Image.open("test.png") image_binary = BytesIO() image.save(image_binary, "PNG") image_binary = image_binary.getvalue() await ctx.send(file=discord.File(fp=image_binary)) Error: Traceback (most

问题 This collage is what im supposed to get.... import PIL from PIL import Image from PIL import ImageEnhance from PIL import ImageDraw # read image and convert to RGB image=Image.open("readonly/msi_recruitment.gif") image=image.convert('RGB') # build a list of 9 images which have different brightnesses enhancer=ImageEnhance.Brightness(image) images=[] for i in range(1, 10): images.append(enhancer.enhance(i/10)) # create a contact sheet from different brightnesses first_image=images[0] contact

问题 I know and have seen tons of documentations explaining about how to capture mouse movement within a given window using mouseclick events in opencv. What I want to know is that if is there a way to capture mouse movements (x,y co-ordinates) for the entire screen of my system. Any link, documentation or code snippet will be really helpful to proceed me with the same. 回答1: Depending on your OS, you can do that with pyautogui like this: #!/usr/bin/env python3 import time import pyautogui for i in

问题 Using this script i am trying to take a screenshot of my desktop of a particular area.(using Tkinter gui) But with this code i can only take screenshot of the fix area (frame) of desktop.

问题 I'm trying to identify the colors of the used color palette of an image with PIL/pillow. I've tried the following: image[x,y] : this will only give me the index number of the corresponding pixel (i.e. 1 ) image.getpixel((x,y)) : again, this will only give me the index number of the corresponding pixel (i.e. 1 ) image.getcolors() : This will give me the number of pixels and their corresponding index number (i.e. [(2, 1), (2, 0)] ) image.palette : Returns a "PIL.ImagePalette.ImagePalette object

问题 i'm trying to add an Image to the first column of every row on a treeview, but no matter what I do, always end up with the name of the object "pyimage1" showed instead of the actual image. As this image shows The code that i'm using is something like this. from tkinter import PhotoImage. self._img = PhotoImage(file="resources\information_picto.gif") self.tree.insert('', 'end', values= self._image,self.name, self.status, self.cores, self.turn, self.added_time) I've tried with png, with the
