public class SoVRSegyTraceHeaderBytePosition
extends Inventor

SEGY file trace header field description. This class allows describing the position, the length and the format of each field within a SEGY trace header. (SEGY is a widely used format for storing seismic data). It is used to query this information from the SEGY file reader (see SoVRSegyFileReader.getSegyTraceHeader). See also SoVRSegyFileHeader.

toArray

public static SoVRSegyTraceHeaderBytePosition[] toArray(long nativeArray,
                                                        long length)

getBytePosition

public byte getBytePosition(SoVRSegyTraceHeaderBytePosition.TraceAttributes attr)

setByteFormat

public void setByteFormat(SoVRSegyTraceHeaderBytePosition.TraceAttributes attr,
                          SoVRSegyTraceHeaderBytePosition.TraceByteFormats format)

Sets/Gets the field format of a specific attribute within the trace header. The default format for all the fields is either SEGY_INTEGER16_FORMAT or SEGY_INTEGER32_FORMAT, see the class SoVRSegyTraceIdHeader below. For instance calling setByteFormat(TraceAttribute.SEGY_SX, SEGY_IEEE_FLOAT_FORMAT) means that the attribute source coordinate X should be coded as a IEEE float.

setBytePosition

public void setBytePosition(SoVRSegyTraceHeaderBytePosition.TraceAttributes attr,
                            byte position)

Sets/Gets the byte position of a specific attribute within the trace header. For instance calling setBytePosition(TraceAttribute.SEGY_SX, 71) means that the attribute source coordinate X should be retreived at from the byte position 71 (instead of 73 by default).

getByteLength

public byte getByteLength(SoVRSegyTraceHeaderBytePosition.TraceAttributes attr)

Gets the field length of a specific attribute within the trace header. Valid values are 1, 2, and 4 (char, short, int/ieee/ibm, respectively).

getFieldValue

public int getFieldValue(SoVRSegyTraceHeaderBytePosition.TraceAttributes attr,
                         SoVRSegyTraceIdHeader trHdr)

Gets the value of a specific field. The way the value is retrieved depends on its position and format. These parameters might be specified by setBytePosition() and setByteFormat() respectively.

getByteFormat

public SoVRSegyTraceHeaderBytePosition.TraceByteFormats getByteFormat(SoVRSegyTraceHeaderBytePosition.TraceAttributes attr)
