  26 .TH TIFFWriteEncodedTile 3TIFF "December 16, 1991" "libtiff"
  27 .SH NAME
  28 TIFFWritedEncodedTile \- compress 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 TIFFWriteEncodedTile(TIFF *" tif ", ttile_t " tile ", tdata_t " buf ", tsize_t " size ")"
  35 .SH DESCRIPTION
  36 Compress
  37 .I size
  38 bytes of raw data from
  39 .I buf
  40 and
  41 .B append
  42 the result to the end of the specified tile. Note that the value of
  43 .I tile
  44 is a ``raw tile number.'' That is, the caller must take into account whether
  45 or not the data are organized in separate places (\c
  46 .IR PlanarConfiguration =2).
  47 .IR TIFFComputeTile
  48 automatically does this when converting an (x,y,z,sample) coordinate quadruple
  49 to a tile number.
  50 .SH NOTES
  51 The library writes encoded data using the native machine byte order. Correctly
  52 implemented
  53 .SM TIFF
  54 readers are expected to do any necessary byte-swapping to correctly process
  55 image data with BitsPerSample greater than 8.
  56 .SH "RETURN VALUES"
  57 \-1 is returned if an error was encountered. Otherwise, the value of
  58 .IR size
  59 is returned.
  60 .SH DIAGNOSTICS
  61 All error messages are directed to the
  62 .BR TIFFError (3TIFF)
  63 routine.
  64 .PP
  65 \fB%s: File not open for writing\fP.
  66 The file was opened for reading, not writing.
  67 .PP
  68 \fBCan not write tiles to a stripped image\fP.
  69 The image is assumed to be organized in strips because neither of the
  70 .I TileWidth
  71 or
  72 .I TileLength
  73 tags have been set with
  74 .BR TIFFSetField (3TIFF).
  75 .PP
  76 \fB%s: Must set "ImageWidth" before writing data\fP. The image's width has not
  77 be set before the first write. See
  78 .BR TIFFSetField (3TIFF)
  79 for information on how to do this.
  80 .PP
  81 \fB%s: Must set "PlanarConfiguration" before writing data\fP. The organization
  82 of data has not be defined before the first write. See
  83 .BR TIFFSetField (3TIFF)
  84 for information on how to do this.
  85 .PP
  86 \fB%s: No space for tile arrays"\fP.
  87 There was not enough space for the arrays that hold tile offsets and byte
  88 counts.
