Editing Lima ROI counters

BLISS provides a helper function to edit Lima ROI (Region-Of-Interest) via Flint, to create counters automatically from areas defined by the user graphically using mouse dragging.

The edit_roi_counters function takes: * a Lima detector object * an optional acquisition time

If an acquisition time is given, ct(acq_time, detector) is executed before the ROI counter edition is started.

Note

SCAN_DISPLAY.auto is set to True in order to make sure Flint will display the image

If no acquisition time is given, it assumes the last scan was made with the detector, and the image from the last scan will be used for ROI editing.

>>> edit_roi_counters(lima_simulator, 0.1)
Waiting for ROI edition to finish on lima_simulator [default]...                                                             

Clicking on the Apply button once ROI edition is terminated returns to the BLISS shell prompt.
