pillow

问题 I am having trouble running a compiled executable that includes pillow. I have used pyinstaller which seems to compile well enough, however after running the exe, an error is thrown. Seems there is a conflict with '_imaging' being referenced instead of 'Image'. First off, I find it strange how pillow installs to a PIL directory rather than a pillow and the modules are also referenced as PIL. I doubt that has anything to do with the problem though. There isn't actually a _imaging.py file in

问题 I installed Pillow 3.0.0 by pip onto my Python3.5 on my 32bit windows7 PC. from PIL import Image gives me: File "C:\Python 3.5\lib\site-packages\PIL\Image.py", line 66, in <module> from PIL import _imaging as core ImportError: DLL load failed: The specified procedure could not be found. The Image file contains this comment: # If the _imaging C module is not present, Pillow will not load. The PIL directory contains no -imaging files. There was one called _imaging.cp35-win32.pyc but it has

问题 I am using pytesseract to extract text from images. Before extracting text with pytesseract, I use Pillow and cv2 to reduce noise and enhance the image: import numpy as np import pytesseract from PIL import Image, ImageFilter, ImageEnhance import cv2 img = cv2.imread('ss.png') img = cv2.resize(img, (0,0), fx=3, fy=3) cv2.imwrite("new.png", img) img1 = cv2.imread("new.png", 0) #Apply dilation and erosion kernel = np.ones((2, 2), np.uint8) img1 = cv2.dilate(img1, kernel, iterations=1) img1 =

问题 I have two images: and I want to export an image that just has the red "Hello" like: So I am running a simple deduction python script: from PIL import Image import numpy as np root = '/root/' im1 = np.asarray(Image.open(root+'1.jpg')) im2 = np.asarray(Image.open(root+'2.jpg')) deducted_image = np.subtract(im1, im2) im = Image.fromarray(np.uint8(deducted_image)) im.save(root+"deduction.jpg") But this returns: rather than the above. What am I doing wrong? Also do I need numpy or can I do this

问题 I am trying to create images programatically on Python using Pillow library but I'm having problems with the image quality of the text inside the image. I want to save the Image the I generate to PNG, so I'm setting the DPI when saving according to this, but whether I save with dpi=(72,72) or dpi=(600,600) it visually looks the same. My code for doing it is the following: from PIL import Image, ImageDraw, ImageFont def generate_empty_canvas(width, height, color='white'): size = (width, height

问题 I am trying to do some image resizing on my Django application running on AWS Elastic beanstalk, so I am trying to install Pillow to do the job.

问题 I am rather new to python and have a problem with the save function of the Pillow fork of PIL. With this minimal example import Image im = Image.new("RGB", (200, 30), "#ddd") im.save("image.png") I get the following error: File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 1667, in save raise KeyError(ext) # unknown extension KeyError: '.png' The corresponding lines in the save function are preinit() [...] try: format = EXTENSION[ext] except KeyError: raise KeyError(ext) # unknown

问题 I'm to draw text over an image in a Django application hosted on an Ubuntu 14.04 LTS machine. Pillow 4.2.1 is my lib of choice. I've successfully accomplished this task via ImageDraw imported from PIL (The actual code is at the end of this question) My code works perfectly for languages such as English, French or Spanish. But not for naturally cursive languages like Arabic, Persian or Urdu. In such cases, it draws each letter separately. E.g. فارسی (Persian) is drawn as: Note that I installed
