Method Details
-
allowSignedByte
boolean allowSignedByte()Indicates how byte values will be written. If true, byte values are written as FITS unsigned bytes with an offset as discussed in the FITS standard (TFORM=B
,TZERO=-128
); if false, they are written as signed shorts (TFORM=I
).- Returns:
- true to write as bytes, false to write as shorts
-
allowZeroLengthString
boolean allowZeroLengthString()Indicates whether columns with TFORMn=0A may be output. Such columns are explicitly permitted by the FITS standard, but they cause failures in some versions of CFITSIO.- Returns:
- false to block TFORMn=0A column output, true to allow it
-
getWide
WideFits getWide()Returns the convention for representing over-wide tables.- Returns:
- wide table convention, or null to avoid writing wide tables
-
getPadCharacter
byte getPadCharacter()Returns the byte value with which under-length string (character array) values should be padded. This should normally be one of 0x00 (ASCII NUL) or 0x20 (space).- Returns:
- padding value for character array data
