问题 EDIT: Actually, I need a way I can read the lines and extract the pixel info into some structure so I can use the putpixel function to create an image based on the ppm p3 file. I've been trying this for so long and I can't just get it right. I'm working with Python Imaging Library (PIL) and I want to open a PPM image and display it as an image on the screen. How can I do that using only PIL? this is my ppm image. it's just a 7x1 image that i created. P3 # size 7x1 7 1 255 0 0 0 201 24 24 24

问题 I have used pyBarcode library to generate Barcode in my software and its works perfectly fine while I load it from command line but once I freeze the entire software using py2exe I am getting IO error while generating the barcode. File "panels.pyc", line 383, in generate File "barcodeGenerator.pyc", line 9, in generate File "barcode\base.pyc", line 68, in save File "barcode\codex.pyc", line 251, in render File "barcode\base.pyc", line 103, in render File "barcode\writer.pyc", line 188, in

问题 So, the idea here is that the given text, which happens to be Devanagari character such as संस्थानका कर्मचारी and I want to convert given text to image. Here is what I have attempted. def draw_image(myString): width=500 height=100 back_ground_color=(255,255,255) font_size=10 font_color=(0,0,0) unicode_text = myString im = Image.new ( "RGB", (width,height), back_ground_color ) draw = ImageDraw.Draw (im) unicode_font = ImageFont.truetype("arial.ttf", font_size) draw.text ( (10,10), unicode_text

问题 I have a set of images that are output from a code, and I want to be able to remove all of the excess whitespace within the image so that it reduces the image to only the text within the image. This is the pertinent code: from PIL import Image, ImageFont, ImageDraw, ImageChops from docx import Document import textwrap import re doc = Document('Patents.docx') docText = ''.join(paragraph.text for paragraph in doc.paragraphs) def trim(im, color): bg = Image.new(im.mode, im.size, color) diff =

问题 I'm trying to create a transparent gif through pillow in python through this code frames[0].save(path+'/final.gif', format='GIF', append_images=frames[1:], save_all=True, duration=33, loop=0,transparency=0) where frame is a list of PIL.Image files. The end result is that you can see the image in the previous frame This hasn't happened before and I was able to create this gif without any problems 回答1: I solved this problem by setting disposal = 2 , you can edit your code as: frames[0].save

问题 Follow up question from Replacing a quadrilateral with a square generated from PIL.QUAD I am able to overlay the image perfectly, but want ways to blur just the edges. I took a look at composite_channel and the list of operators (http://docs.wand-py.org/en/0.4.1/wand/image.html#wand.image.COMPOSITE_OPERATORS) and while luminize seems to work well as an operator, it still does not blur the edges. Are there ways to do this with wand ? 来源： https://stackoverflow.com/questions/61276080/blending

问题 I tried to resize some image files and save them in other directory. and there's not any error but files didn't save in directory I designated. path = r"C:\Users\abc123\Desktop\various_image" valid_images = [".jpg",".gif",".png",".tga"] for f in os.listdir(path): ext = os.path.splitext(f)[1] if ext.lower() not in valid_images: continue im = Image.open(os.path.join(path,f)) resize_im = im.resize((256, 256), Image.ANTIALIAS) ext = ".jpg" resize_im.save(r"C:\Users\abc123\Desktop\Movie" + f + ext

问题 The font size has to dynamically adapt to different the text length, which can vary a lot. Currently I have a ton of code, basically manually checking how long the incoming text is and manually giving a font size for that. There has to be a better solution. I don't think I can use ImageDraw.textsize. Has anyone a solution for this kinda problem? Thanks 回答1: I don't know other method then ImageDraw.textsize() in for -loop which checks it for different font sizes. Now I found that in version 8

问题 I have a transparent logo that I want to convert to grayscale using OpenCV. I am using the following code def to_grayscale(logo): gray = cv2.cvtColor(logo, cv2.COLOR_RGB2GRAY) blur = cv2.GaussianBlur(gray, (5, 5), 0) canny = cv2.Canny(blur, 50, 150) # sick return canny This is the image variable: brand_logo = Image.open(current_dir + '/logos/' + logo_image, 'r').convert('RGBA') brand_logo = to_grayscale(brand_logo) And this is the error: TypeError: Expected Ptr<cv::UMat> for argument 'src' I
