Add keepdim param to mean/sum. Allow negative indices.0.13.6 (2018-12-28)Fix display RGB calculation on integer images.Add methods for better control of data ref count.0.13.5 (2018-12-11)Add setters for timezone, timezone_offset, and timestamp.0.13.4 (2018-11-13)Add measure_relative_translation function to xdata. Utilize in align.Generalize align and register sequence to accept any combo of sequence and collection dimensions.Provide more descriptive data dimensions string.0.13.3 (2018-06-15)Fix squeeze to not remove last datum dimension.Add re-dimension function (changes data description, keeps data layout in memory the same).Ensure that data_descriptor is a copy, not a reference, when accessed from DataAndMetadata.Add calibration and data_descriptor creation methods to xdata_1_0.Change crop to always produce the same size crop, even if out of bounds. Fill out of bounds with zero.Add crop_rotated to handle crop with rotation (slower).0.13.2 (2018-05-23)Automatically promote ndarray and constants (where possible) to xdata in operations.Fix FFT-1D scaling and shifting inconsistency.Add average_region function (similar to sum_region).0.13.1 (2018-05-21)Fix timezone bug.0.13.0 (2018-05-10)Initial version online.
