segpy.datatypes module¶

Mappings between the coding systems used for sample types.

class segpy.datatypes.DataSampleFormat¶

Bases: enum.IntEnum

Data sample format code. Mandatory for all data. 1 = 4-byte IBM floating-point, 2 = 4-byte, two’s complement integer, 3 = 2-byte, two’s complement integer, 4 = 4-byte fixed-point with gain (obsolete), 5 = 4-byte IEEE floating-point, 6 = Not currently used, 7 = Not currently used, 8 = 1-byte, two’s complement integer.

FLOAT32 = 5¶

IBM = 1¶

INT16 = 3¶

INT32 = 2¶

INT8 = 8¶

class segpy.datatypes.Limits(min, max)¶

Bases: tuple

max¶: Alias for field number 1

min¶: Alias for field number 0

class segpy.datatypes.SegYType¶

Bases: str, enum.Enum

An enumeration.

FLOAT32 = 'float32'¶

IBM = 'ibm'¶

INT16 = 'int16'¶

INT32 = 'int32'¶

INT8 = 'int8'¶

NNINT16 = 'nnint16'¶

NNINT32 = 'nnint32'¶

NNINT8 = 'nnint8'¶

segpy.datatypes.size_in_bytes(ctype)¶: The size in bytes of a ctype.
