  26 .TH TIFFWriteTile 3TIFF "November 29, 1999" "libtiff"
  27 .SH NAME
  28 TIFFWriteTile \- encode and write a tile of data to an open
  29 .SM TIFF
  30 file
  31 .SH SYNOPSIS
  32 .B "#include <tiffio.h>"
  33 .sp
  34 .BI "tsize_t TIFFWriteTile(TIFF *" tif ", tdata_t " buf ", uint32 " x ", uint32 " y ", uint32 " z ", tsample_t " sample ")"
  35 .SH DESCRIPTION
  36 Write the data for the tile
  37 .I containing
  38 the specified coordinates. The data in
  39 .I buf
  40 are is (potentially) compressed, and written to the indicated file, normally
  41 being appended to the end of the file. The buffer must be contain an entire
  42 tile of data. Applications should call the routine
  43 .IR TIFFTileSize
  44 to find out the size (in bytes) of a tile buffer. The
  45 .I x
  46 and
  47 .I y
  48 parameters are always used by
  49 .IR TIFFWriteTile .
  50 The
  51 .I z
  52 parameter is used if the image is deeper than 1 slice (\c
  53 .IR ImageDepth >1).
  54 The
  55 .I sample
  56 parameter is used only if data are organized in separate planes (\c
  57 .IR PlanarConfiguration =2).
  58 .SH "RETURN VALUES"
  59 .IR TIFFWriteTile
  60 returns \-1 if it detects an error; otherwise the number of bytes in the tile
  61 is returned.
  62 .SH DIAGNOSTICS
  63 All error messages are directed to the
  64 .BR TIFFError (3TIFF)
  65 routine.
