Looks like the image is too big and the window simply doesn’t fit the screen. Create window with the cv2.WINDOW_NORMAL flag, it will make it scalable. Then you can resize it to fit your screen like this: from __future__ import division import cv2 img = cv2.imread(‘1.jpg’) screen_res = 1280, 720 scale_width = screen_res[0] / img.shape[1] … Read more
Short Answer Add the image’s native width and height in pixels as attributes on the image. This lets the browser calculate the aspect ratio for the image. <img width=”600″ height=”400″ src=”some-image.webp”/> Long Answer width: 100% does not give an element an explicit width. What it does is define the width relative to it’s parent container. … Read more
The specific documentation is at http://effbot.org/imagingbook/concepts.htm: Mode The mode of an image defines the type and depth of a pixel in the image. The current release supports the following standard modes: 1 (1-bit pixels, black and white, stored with one pixel per byte) L (8-bit pixels, black and white) P (8-bit pixels, mapped to any … Read more
There is Python code to convert RGB to HSV (and vice versa) in the colorsys module in the standard library. My first attempt used rgb_to_hsv=np.vectorize(colorsys.rgb_to_hsv) hsv_to_rgb=np.vectorize(colorsys.hsv_to_rgb) to vectorize those functions. Unfortunately, using np.vectorize results in rather slow code. I was able to obtain roughly a 5 times speed up by translating colorsys.rgb_to_hsv and colorsys.hsv_to_rgb into … Read more
After some intense struggle, I finally managed to make it work after learning a bit how to use the FFmpeg and libx264 C APIs for my specific purpose, thanks to the useful information that some users provided in this site and some others, as well as some FFmpeg’s documentation examples. For the sake of illustration, … Read more
Yes it is possible and pretty easy once you understand tkinter, here’s a quick script: from Tkinter import * from tkFileDialog import askopenfilename import Image, ImageTk if __name__ == “__main__”: root = Tk() #setting up a tkinter canvas with scrollbars frame = Frame(root, bd=2, relief=SUNKEN) frame.grid_rowconfigure(0, weight=1) frame.grid_columnconfigure(0, weight=1) xscroll = Scrollbar(frame, orient=HORIZONTAL) xscroll.grid(row=1, column=0, … Read more
Well, if I understood correctly, you want to iterate through the pixels in the image, perform some kind of test, and if it passes you want to store that pixel in an array. Here´s how you could do that: using System.Drawing; Bitmap img = new Bitmap(“*imagePath*”); for (int i = 0; i < img.Width; i++) … Read more
