ExpandPyr

DESCRIPTION

Converts a compressed pyramid to the fully expanded form used in release 1 of Explorer. If an expanded pyramid is passed to the Input port, the output refers to the input pyramid (no copy is made).

INPUTS

Port: Input
Type: Pyramid
Constraints: 1..-layer
Constraints: optional-baseLat
Constraints: n-D compression
Constraints: n-compression type
The compressed pyramid that is to be expanded.

WIDGETS

OUTPUTS

Port: Expanded
Type: Pyramid
Constraints: 1..-layer
Constraints: optional-baseLat
Constraints: n-D compression
Constraints: none-compression type
The fully expanded copy of the input, or a pointer to the input pyramid in the case of an already expanded input.

PROBLEMS

Expansion of a pyramid may be expensive in both time and space.
