Purpose

The module Replicate replicates an image according to the specified number of replicas in each image dimension.

Details

Fractional numbers of replicas lead to a replication of a fraction of the input image.

For example, the replication vector 1.5 1 1 1 1 1 leads to a replication of the first half of the input image in the x direction.

The output page size is usually equal to the input page size.

If a any dimension of the input page extents exceeds the image extents, the page extents will be replaced by the smaller image extents in that dimension.

In the case the input page size (possibly only after the mentioned adjustment) will be smaller than a 2D XY slice, the output pages are adjusted to 2D pages of size (extX, extY) to avoid inefficient page sizes of larger images in networks. If these 2D pages would become too large (> 2^20), both x and y extents will be divided by a suitable power of 2.

Arbitrary page sizes are allowed for the input.

Tips

If you need to replicate in two dimensions—for example, to spread a per-slice maximum or mean result obtained from the use of SubImageStatistics on an original image to an image that extends the original for further use—it may be faster to use Replicate twice; first replicating in the x direction and then in the y direction.
