msg.encoding map ?

[CRAZY-LY]

What are the corresponding rules of msg.encoding and "encoding" in bridge.imgmsg_to_cv2(msg, "encoding")?(encoding = "bgr8" or "rgb8"...) if msg.encoding.find("mono8")!=-1 : pix_fmt = "gray" #np_arr = np.fromstring(msg.data, np.uint8) if opt_display_images: cv_image = bridge.imgmsg_to_cv2(msg, "bgr8") elif msg.encoding.find("bgr8")!=-1 : pix_fmt = "bgr24" #np_arr = np.fromstring(msg.data, np.uint8) if opt_display_images: cv_image = bridge.imgmsg_to_cv2(msg, "bgr8") elif msg.encoding.find("rgb8")!=-1 : pix_fmt = "rgb24" #np_arr = np.fromstring(msg.data, np.uint8) if opt_display_images: cv_image = bridge.imgmsg_to_cv2(msg, "bgr8")
