Import Images¶
Widget: Open Files¶
- File type: None
- File path: Select a file to be imported, the file can be a tiff, h5, png, jpg.
- Layer name: Define the name of the output layer, default is either image or label.
- Layer type: Select the type of input you are loading.
- Stack layout: t for time, c for channel, xyz for dimensions, e.g.: tzyxc will be reshaped to [T][C][Z]YX. Invert an axis by adding `-` infront of the letter. Truncate the data before importing with a slice after the letters, e.g. txyz[:3,:,:]: the entries follow the layout as written, before reordering, an integer drops its axis.
Stack Layout¶
When you pick a file, the Stack layout field is prefilled. OME-TIFF files
use the axis string from their OME-XML metadata, h5 and zarr files use
the axis_order attribute written on export, and everything else falls back
to a guess from the array shape. The layout can be any permutation of the
letters t, c, z, y, x that match your file, so a 3D time series
gets prefilled as TZYX.
You can invert an axis by prepending it with a minus.
Also you can slice the data by appending, e.g. tczxy[:10,2] to only load the
first ten frames of the third channel.
The slicing functionality can also be used for cropping already during the
import (CXYZ[1,:50,:50,:10]).
