I can’t get my App to draw an image.
The code I found here:
#OpenCV: Drawing Functions in OpenCV
import numpy as np
import cv2 as cv
img = np.zeros((512,512,3), np.uint8)
I guess this code should draw an image but it does nothing.
it correctly draws a line into an existing image.
if you expected to see a window showing your image
– your code does not do that.
You must have skipped the preceding two tutorials.
OpenCV is a library for people who are experienced programmers.
Please seek out a forum for beginners. We don’t have the capacity to help people learn how to program.
Perhaps you would like to learn about “PyGame”.
