Tiling

To tile a SlideImage object, dlup offers a set of convenient settings to achieve the most common use cases.

Mode

Dlup currently offers three policies to deal with overflowing tiles during dataset generation. In this section we’ll provide visual examples of the three modalities.

Skip

As the name suggests, this policy skips the last tile if it was going to overflow beyond the slide boundary.

Overflow

This policy pads the bottom and right border of the slide with zeros, so that the last row and the last column will contain zero-padded tiles. This will ensure that their size is consistent with all other tiles.

Crop

This is an additional option that may be included with the --crop flag when using dlup wsi tile. It defines whether overflowing tiles should be cropped (as opposed to zero-padded).
