create_image_original()

This function creates the original image based on the configuration view. The function will check the type of media source specified in the configuration view, and proceed accordingly. The function can handle different types of media sources including a camera stream, a video file, or an image file. The function sets the video and image variables based on the media source. If the media source is a camera stream, the function will start a timer to capture frames. If the media source is a video file, the function will capture frames for the duration of the video. If the media source is an image file, the function will read the image into memory.

Returns:

None

create_image_result()

Create the result image based on the current view and configuration settings.

If the load_saved_image flag is True, the function crops the original image based on the state of the state_rubberband flag. If it is False, the function checks the state of the state_recent_view flag and performs the following actions: - If the state is “AnypointView”, it rotates the image by the __angle_rotate angle, and remaps the image

based on the __map_x_anypoint and __map_y_anypoint maps. If set_draw_polygon is True, it draws a polygon on the original image using the same maps. It then sets image_result to the resulting image and sets __image_original to the original image with the crosshair drawn on it.

• If the state is “PanoramaView”, it rotates the image by the __angle_rotate angle, and remaps the image based on the __map_x_pano and __map_y_pano maps. If change_panorama_mode is “car”, it crops the resulting image using the __crop_panorama_car method. Otherwise, it crops it using the __crop_panorama_tube method. If set_draw_polygon is True, it draws a polygon on the original image using the same maps. It then sets image_result to the resulting image and sets __image_original to the original image with the crosshair drawn on it.

• If the state is not “AnypointView” or “PanoramaView”, it rotates the image by the __angle_rotate angle and sets image_result to the resulting image. It then sets __image_original to the original image with the crosshair drawn on it.

After creating the result image, the function emits a signal with the resulting image, and sets the image_height and image_width properties of the class.

If the state_rubberband flag is True, the function calls the crop_image method on the resulting image, which will emit a signal with the cropped image.

If the load_saved_image flag is False and the state_rubberband flag is False, the function emits a signal with the resulting image.
