NAME
       TIFFReadEncodedTile  - read and decode a tile of data from an open TIFF
       file

SYNOPSIS
          #include <tiffio.h>

       int TIFFReadEncodedTile(TIFF *tif, ttile_t tile, tdata_t  buf,  tsize_t
       size)

DESCRIPTION
       Read  the  specified  tile of data and place up to size bytes of decom-
       pressed information in the (user supplied) data buffer.

NOTES
       The value of tile is a "raw tile number". That is, the caller must take
       into  account  whether or not the data are organized in separate planes
       (PlanarConfiguration = 2).  TIFFComputeTile() automatically  does  this
       when  converting  an (x,y,z,sample) coordinate quadruple to a tile num-
       ber. To read a full tile of data the data buffer should be at least  as
       large as the value returned by TIFFTileSize().

       The library attempts to hide bit- and byte-ordering differences between
       the image and the native machine by converting data to the  native  ma-
       chine  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;
       TIFFReadEncodedTile() returns -1 if an error was encountered.

DIAGNOSTICS
       All error messages are directed to the TIFFErrorExtR() routine.
