问题 I want to display a gif image using Pillow Here is my simple code: from tkinter import * from PIL import Image, ImageTk import tkinter as Tk image = Image.open("Puissance4.gif") image.show() But nothing happens... All help will be appreciated Thanks! 回答1: PIL provides a show method which attempts to detect your OS and choose an appropriate viewer. On Unix it tries calling the imagemagick command display or xv . On Macs it uses open , on Windows it uses... something else. If it can't find an

问题 I am trying to resize some images, most of which are JPG. But in a few images, I am getting the error: Traceback (most recent call last): File "image_operation_new.py", line 168, in modifyImage tempImage.save(finalName); File "/Users/kshitiz/.virtualenvs/django_project/lib/python2.7/site- packages/PIL/Image.py", line 1465, in save save_handler(self, fp, filename) File "/Users/kshitiz/.virtualenvs/django_project/lib/python2.7/site- packages/PIL/JpegImagePlugin.py", line 455, in _save raise

问题 This is a basic transform question in PIL. I've tried at least a couple of times in the past few years to implement this correctly and it seems there is something I don't quite get about Image.transform in PIL. I want to implement a similarity transformation (or an affine transformation) where I can clearly state the limits of the image. To make sure my approach works I implemented it in Matlab. The Matlab implementation is the following: im = imread('test.jpg'); y = size(im,1); x = size(im,2

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 5 years ago . Is there any way to import all the images inside a directory (the directory location is known). If it helps, I have already found a way of finding out the length of the directory. What I'm not sure about is how I can import the images (using PIL/Pillow) into either a list or a dictionary. 回答1: I'd

问题 I am using the Pillow fork of PIL and keep receiving the error OSError: cannot identify image file <_io.BytesIO object at 0x103a47468> when trying to open an image. I am using virtualenv with python 3.4 and no installation of PIL. I have tried to find a solution to this based on others encountering the same problem, however, those solutions did not work for me. Here is my code: from PIL import Image import io # This portion is part of my test code byteImg = Image.open("some/location/to/a/file

问题 I have this image with size 128 x 128 pixels and RGBA stored as byte values in my memory. But from PIL import Image image_data = ... # byte values of the image image = Image.frombytes('RGBA', (128,128), image_data) image.show() throws the exception ValueError: not enough image data Why? What am I doing wrong? 回答1: You can try this: image = Image.frombytes('RGBA', (128,128), image_data, 'raw') Source Code: def frombytes(mode, size, data, decoder_name="raw", *args): param mode: The image mode.

问题 I was trying this code: im = Image.open("myimage") colors = im.getcolors() print colors and it returns "None". So I tried this: im = Image.open("myimage") size = im.size colors = im.getcolors(size[0]*size[1]) and when I "print colors" with this, Python basically crashes. I'm not using a huge image. How can I make it work? My goal is to know from an image how many pixels are closer to black and how many px are closer to white. Maybe im.getcolors it's not the right solution? 回答1: The image has
