When installed and enabled in the options, it adds an option that when enabled will make napari load tiffs via memory mapping instead of fully into RAM.

That is, .tif and .tiff files will be loaded into memory using memory mapping, which loads the data directly from disk instead of loading the file at once into RAM. This is beneficial for large files that may not fit into available RAM.


This napari plugin was generated with copier using the napari-plugin-template.
