I display a camera snapshot image in a pyqtgraph window, but I can't figure out or find out how to close the window. When I use .close(), the window goes white, but it doesn't close.
Below, I use "pg.image( ) which opens an Ubuntu window that shows the image. .close() just makes contents of window go white. The only way to close the window is to click its Ubuntu red X in the upper right.
import uvc
import pyqtgraph as pg
import logging
from PyQt4 import QtGui
import sys
""" for file read & write """
import numpy
from time import sleep
def camera_to_snapshot( ):
dev_list = uvc.device_list()
cap = uvc.Capture(dev_list[ 0]['uid'])
modes = cap.avaible_modes
cap.frame_mode = modes[1]
frame = cap.get_frame_robust()
frame.img
print("camera_to_snapshot done.")
return frame
def camera_to_image( ):
raw_image = camera_to_snapshot( ).img
return raw_image
def camera_to_window( ):
snapshot_image = camera_to_image( )
pg.image( snapshot_image )
return
camera_to_window()
sleep( 10 )
how to close window??
I am on Ubuntu 16.04 (Xenial Xerus).
