This operation is performed with a +lookup table, which is returned using the +.IR TIFFGetBitRevTable +function. +.I reversed +parameter specifies which table should be returned. Supply +.I 1 +if you want bit reversal table. Supply +.I 0 +to get the table that do not reverse bit values. It is a lookup table that can +be used as an +.IR "identity function" ; +i.e. +.IR "TIFFNoBitRevTable[n] == n" . +.SH DIAGNOSTICS +None. +.SH "SEE ALSO" +.BR libtiff (3TIFF) +.PP +Libtiff library home page: +.BR http://www.remotesensing.org/libtiff/ |
