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).   TIFF-
       ComputeTile  automatically  does this when converting an (x,y,z,sample)
       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(3TIFF) 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(3TIFF).

       %s:  Must  set  "ImageWidth" before writing data. The image's width has
       not be set before the first write. See TIFFSetField(3TIFF) 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(3TIFF) 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.
