ptypy.utils.array_utils.pad_lr

ptypy.utils.array_utils.pad_lr(A, axis, l, r, fillpar=0.0, filltype='scalar')

Pads ndarray A orthogonal to axis with l layers (pixels,lines,planes,…) on low side an r layers on high side.

Parameters:

• A (array-like) – Input array

• axis (int) – Pads orthogonal to axis on with l layers (pixels,lines, planes,…) on low side an r layers on high side.

• l (int) – Pads orthogonal to axis on with l layers (pixels,lines, planes,…) on low side an r layers on high side.

• r (int) – Pads orthogonal to axis on with l layers (pixels,lines, planes,…) on low side an r layers on high side.

• fillpar (scalar) – Scalar fill parameter for filltype=scalar fill.

• filltype (str) –

  • ‘scalar’, uniformly pad with fillpar

  • ’mirror’, mirror A

  • ’periodic’, periodic fill

  • ’custom’, pad according arrays found in fillpar

Returns:

Padded array

Return type:

ndarray
