EBSDDetector.crop(extent: Tuple[int, int, int, int] | List[int]) EBSDDetector[source]#

Return a new detector with its shape cropped and pc values updated accordingly.

Parameters:
extent

Tuple with four integers: (top, bottom, left, right).

Returns:
new_detector

A new detector with a new shape and PC values.

Examples

>>> import kikuchipy as kp
>>> det = kp.detectors.EBSDDetector((6, 6), pc=[3 / 6, 2 / 6, 0.5])
>>> det
EBSDDetector(shape=(6, 6), pc=(0.5, 0.333, 0.5), sample_tilt=70.0, tilt=0.0, azimuthal=0.0, binning=1.0, px_size=1.0 um)
>>> det.crop((1, 5, 2, 6))
EBSDDetector(shape=(4, 4), pc=(0.25, 0.25, 0.75), sample_tilt=70.0, tilt=0.0, azimuthal=0.0, binning=1.0, px_size=1.0 um)

Plot a cropped detector with the PC on a cropped pattern

>>> s = kp.data.nickel_ebsd_small()
>>> s.remove_static_background(show_progressbar=False)
>>> det2 = s.detector
>>> det2.plot(pattern=s.inav[0, 0].data)
>>> det3 = det2.crop((10, 50, 20, 60))
>>> det3.plot(pattern=s.inav[0, 0].data[10:50, 20:60])
