Postby rexmac80625 » Sat Mar 07, 2020 1:07 am

Hello,

how can i display image , like cv.imshow( img )?

draw_image() Is it used like this:
b_img = img.binary([(20,200)]) # Want to change the image data, temporarily use this function to represent
while(True):
b_img.draw_image(b_img, b_img.width(), b_img.height())
