contiguous

When all items in a collection are sequential with no missing indexes. For example, 1, 2, 3 is contiguous whilst 1, 3 is not.

head

The common leading part of items in a collection. For example, the items file.0001.jpg, file.0002.jpg, file.0003.jpg have a head value of file.

padding

The width of the numerical index in a collection. Each item’s index will be padded with zeroes to match this width. A padding of 4 would result in 1 becoming 0001. A padding of 0 means no width is defined and an index can be any width so long as it has no preceding zeroes.

pip
