NAME
       TIFFWritedEncodedTile  -	 compress and write a tile of data to an open
       TIFF file

SYNOPSIS
       #include <tiffio.h>
       tsize_t TIFFWriteEncodedTile(TIFF* tif,	ttile_t	 tile,	tdata_t	 buf,
       tsize_t size)

DESCRIPTION
       Compress	 size bytes of raw data from buf and append the result to the
       end of the specified tile.  Note that 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 places (PlanarConfiguration=2).
       TIFFComputeTile automatically does this when converting an (x,y,z,sam-
       ple) coordinate quadruple to a tile number.

NOTES
       The library writes encoded data using the native machine	 byte  order.
       Correctly  implemented  TIFF  readers are expected to do any necessary
       byte-swapping to	 correctly  process  image  data  with	BitsPerSample
       greater than 8.

RETURN VALUES
       -1  is  returned if an error was encountered.  Otherwise, the value of
       size is returned.

DIAGNOSTICS
       All error messages are directed to the TIFFError(3T) routine.

       %s: File not open for writing.  The file was opened for	reading,  not
       writing.

       Can  not	 write tiles to a stripped image.  The image is assumed to be
       organized in strips because neither of  the  TileWidth  or  TileLength
       tags have been set with TIFFSetField(3T).

       %s:  Must set "ImageWidth" before writing data.	The image’s width has
       not be set before the first write.  See TIFFSetField(3T) for  informa-
       tion on how to do this.

       %s: Must set "PlanarConfiguration" before writing data.	The organiza-
       tion of data has not be defined before the first write.	See  TIFFSet-
       Field(3T) for information on how to do this.

       %s:  No	space  for  tile arrays".  There was not enough space for the
       arrays that hold tile offsets and byte counts.
