pan_view¶

Display data in pan and make ROI selections

class pdsspect.pan_view.PanViewController(image_set, view)[source]¶

Bases: object

Controller for the PanView

Parameters:	image_set (`PDSSpectImageSet`) – pdsspect model view (`PanView`) – View to control

image_set¶: PDSSpectImageSet – pdsspect model

view¶: PanView – View to control

add_ROI(coordinates)[source]¶

Add a region of interest

Parameters:

coordinates (numpy.ndarray or tuple) –

Either a (m x 2) array or a tuple of two arrays

If an array, the first column are the x coordinates and the second are the y coordinates. If a tuple of arrays, the first array are x coordinates and the second are the corresponding y coordinates.

erase_ROI(coordinates)[source]¶

Erase any region of interest inside coordinates

Parameters:

coordinates (numpy.ndarray or tuple) –

Either a (m x 2) array or a tuple of two arrays

If an array, the first column are the x coordinates and the second are the y coordinates. If a tuple of arrays, the first array are x coordinates and the second are the corresponding y coordinates.
