Imshow rotate
WitrynaThese calculation calls can quickly add up and make your code bulky and less readable. The rotate function in imutils helps resolve this problem. Example: # loop over the angles to rotate the image for angle in xrange(0, 360, 90): # rotate the image and display it rotated = imutils.rotate(bridge, angle=angle) cv2.imshow("Angle=%d" % (angle ... WitrynaThe first two dimensions (M, N) define the rows and columns of the image. Out-of-range RGB (A) values are clipped. cmapstr or Colormap, default: rcParams ["image.cmap"] (default: 'viridis') The Colormap instance or registered colormap name used to map scalar data to colors. This parameter is ignored if X is RGB (A).
