VOL_PAD Function

Returns a 3D volume of data padded on all six sides with zeroes.

Usage

result = VOL_PAD(volume, pad_width)

Input Parameters

volume—On input, volume contains the 3D volume of data to pad.

pad_width—The width of the padding around the volume. The size of the resulting volume increases by (2 * pad_width) in all three dimensions.

Returned Value

result—The padded volume data.

Keywords

None.

Discussion

For best results, process volumes with VOL_PAD before transforming them with VOL_TRANS or slicing them with SLICE_VOL. For more information, see the PV‑WAVE User Guide.
