classmethod from_ismrmrd_encoding_limits_type(encoding_limits: encodingLimitsType) → Self[source]

Generate EncodingLimits from ismrmrd.encodingLimitsType.

classmethod from_ismrmrd_header(header: ismrmrdHeader, encoding_number: int = 0) → Self[source]

Extract EncodingLimits from ismrmrd.ismrmrdHeader.

Parameters:

• header (ismrmrdHeader) – ISMRMRD header

• encoding_number (int, default: 0) – Encoding number. An ValueError is raised if the encoding number is out of range for the header.

Returns:

• Extracted EncodingLimits if header.encoding.encodingLimits is not None,

• otherwise an empty EncodingLimits.
