imagesplit.image.combined_image module

Classes for aggregating images from multiple files into a single image

class imagesplit.image.combined_image.Axis(dim_order, dim_flip)

Bases: object

Defines coordinate system used by image coordinates

static from_condensed_format(dim_order_and_flip)

Creates an Axis from a condensed axis array

to_condensed_format()

Creates a condensed Axis array for this Axis

class imagesplit.image.combined_image.CombinedImage(descriptors, file_factory)

Bases: object

A kind of virtual file for writing where the data are distributed across multiple real files.

close()

Closes all streams and files

get_limits()
