TIFFReadEncodedStriMISC. REFERENCE MANUALTIFFReadEncodedStrip(3T)

NAME
     TIFFReadEncodedStrip - read and decode a strip of data  from
     an open TIFF file

SYNOPSIS
     #include <tiffio.h>
     tsize_t  TIFFReadEncodedStrip(TIFF*  tif,  tstrip_t   strip,
     tdata_t buf, tsize_t size)

DESCRIPTION
     Read the specified strip of data and  place  size  bytes  of
     decompressed information in the (user supplied) data buffer.

NOTES
     The value of strip is a ``raw strip number.'' That  is,  the
     caller  must  take  into account whether or not the data are
     organized in separate  planes  (PlanarConfiguration=2).   To
     read  a  full strip of data the data buffer should typically
     be  at  least  as  large   as   the   number   returned   by
     TIFFStripSize(3T).

     The library attempts to hide bit- and byte-ordering  differ-
     ences between the image and the native machine by converting
     data to the native machine order.  Bit reversal is  done  if
     the  FillOrder  tag  is  opposite  to the native machine bit
     order.  16-  and  32-bit  samples  are  automatically  byte-
     swapped  if  the file was written with a byte order opposite
     to the native machine byte order,

RETURN VALUES
     The actual number of bytes of data that were placed  in  buf
     is returned; TIFFReadEncodedStrip returns -1 if an error was
     encountered.

DIAGNOSTICS
     All error messages are directed to  the  TIFFError(3T)  rou-
     tine.
