crop

EBSDDetector.crop(extent: Union[Tuple[int, int, int, int], List[int]]) → EBSDDetector

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 (6, 6), px_size 1 um, binning 1, tilt 0, azimuthal 0, pc (0.5, 0.333, 0.5)
>>> det.crop((1, 5, 2, 6))
EBSDDetector (4, 4), px_size 1 um, binning 1, tilt 0, azimuthal 0, pc (0.25, 0.25, 0.75)

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])
