mantidimaging.gui.windows.live_viewer.presenter module

class mantidimaging.gui.windows.live_viewer.presenter.LiveViewerWindowPresenter(view: LiveViewerWindowView, main_window: MainWindowView)

Bases: BasePresenter

The presenter for the Live Viewer window.

This presenter is responsible for handling user interaction with the view and updating the model and view accordingly to look after the state of the window.

clear_label() → None

Clear the label.

close() → None

Close the window.

convert_image_to_imagestack(image_data) → ImageStack

Convert the single image to an imagestack so the Operations framework can be used

display_image(image_data_obj: Image_Data) → None

Display image in the view after validating contents

handle_deleted() → None

Handle the deletion of the image.

handle_notify_roi_moved() → None

handle_roi_moved(force_clear: bool = False) → None

Recalculate mean intensity in background thread. If already running, request delayed until running calculation complete rather than having overlapping thread that could cause race condition over shared model state.

load_as_dataset() → None

static load_image_from_path(image_path: Path) → ndarray

Load a .Tif, .Tiff or .Fits file only if it exists and returns as an ndarray

model: LiveViewerWindowModel

notify_update_image_list() → None

Notify when image list needs to be updated if not already being updated

old_image_list_paths: list[Path] = []

op_func: Callable

perform_operations(image_data) → ndarray

select_image(index: int) → None

set_dataset_path(path: Path) → None

Set the path to the dataset.

set_roi_enabled(enable: bool)

thread_cleanup(thread: TaskWorkerThread) → None

Handles clean thread closure and updates intensity profile with latest mean calculation. Consume pending recalculation requests if any and trigger recalculation and/or roi updates only if active thread has completed to avoid request loss or race conditions.

try_add_mean(image: Image_Data) → None

try_next_mean_chunk() → None

try_next_mean_chunk_count: int = 0

try_next_mean_chunk_max_retry: int = 100

update_image_list() → None

Update the image in the view.

update_image_modified(image_path: Path) → None

Update the displayed image when the file is modified

update_image_operation() → None

Reload the current image if an operation has been performed on the current image

update_intensity(spec_data: list | ndarray) → None

update_intensity_with_mean() → None
