unu pad -min,--minimum <pos0 ...> -max,--maximum <pos0 ...> [-b,--boundary <behavior>] [-v,--value <val>] [-i,--input <nin>] [-o,--output <nout>]

Pad along each axis to make a bigger nrrd.

• Uses nrrdPad_nva

-min <pos0 ...> , --minimum <pos0 ...>

low corner of bounding box.

• <int> gives 0-based index
• M, M+<int>, M-<int> give index relative to the last sample on the axis (M==#samples-1).

(1 or more positions)

-max <pos0 ...> , --maximum <pos0 ...>

high corner of bounding box.

• <int> gives 0-based index
• M, M+<int>, M-<int> give index relative to the last sample on the axis (M==#samples-1).

(1 or more positions)

-b <behavior> , --boundary <behavior>

How to handle samples beyond the input bounds:

• “pad”: use some specified value
• “bleed”: extend border values outward
• “mirror”: repeated reflections
• “wrap”: wrap-around to other side

default: “bleed”

-i <nin> , --input <nin>

input nrrd

-o <nout> , --output <nout>

output nrrd (string); default: “-”
