hyperspy.io_plugins.fei module

hyperspy.io_plugins.fei.get_calibration_from_position(position)

Compute the size, scale and offset of a linear axis from coordinates.

This function assumes rastering on a regular grid for the full size of each dimension before rastering over another one. Fox example: a11, a12, a13, a21, a22, a23 for a 2x3 grid.

Parameters

position (numpy array.) – Position coordinates of the axis. Normally as in PositionX/Y of the ser file.

Returns

axis_attr

Return type

dictionary with size, scale, offeset keys.
