import cv2 image_path= #put your image path here #use imread() function to read image data to variable img. img = cv2.imread(image_path) #display image data in a new window with title 'I am an image display window' cv2.imshow('I am an image display window',img) #wait until user hits any key on keyboard cv2.waitKey(0) #close any windows opened by opencv cv2.destroyAllWindows()
要控制屏幕上显示窗口的大小,请在命令之前添加以下命令cv2.imshow:
window_width=800 #size of the display window on the screen window_height=600 #open an empty window with a title. #The flagcv2.WINDOW_NORMALallows the window to be scaleable. cv2.namedWindow('I am an image display window', cv2.WINDOW_NORMAL) #scale the image display window to desired size cv2.resizeWindow('I am an image display window', window_width, window_height)
