.TH TIFFWriteEncodedTile 3T "December 16, 1991"
.SH NAME
TIFFWritedEncodedTile \- compress and write a tile of data to an open
.SM TIFF
file
.SH SYNOPSIS
.B "#include <tiffio.h>"
.br
.B "tsize_t TIFFWriteEncodedTile(TIFF* tif, ttile_t tile, tdata_t buf, tsize_t size)"
.SH DESCRIPTION
Compress
.I size
bytes of raw data from
.I buf
and
.B append
the result to the end of the specified tile.
Note that the value of
.I tile
is a ``raw tile number.''
That is, the caller must take into account whether or not the
data are organized in separate places (\c
.IR PlanarConfiguration =2).
.IR TIFFComputeTile
automatically does this when converting an (x,y,z,sample)
coordinate quadruple to a tile number.
.SH NOTES
The library writes encoded data using the native machine byte order.
Correctly implemented
.SM TIFF
readers are expected to do any necessary byte-swapping to
correctly process image data with BitsPerSample greater than 8.
.SH "RETURN VALUES"
\-1 is returned if an error was encountered.
Otherwise, the value of
.IR size
is returned.
.SH DIAGNOSTICS
All error messages are directed to the
.IR TIFFError (3T)
routine.
.PP
\fB%s: File not open for writing\fP.
The file was opened for reading, not writing.
.PP
\fBCan not write tiles to a stripped image\fP.
The image is assumed to be organized in strips because neither of the
.I TileWidth
or
.I TileLength
tags have been set with
.IR TIFFSetField (3T).
.PP
\fB%s: Must set "ImageWidth" before writing data\fP.
The image's width has not be set before the first write.
See
.IR TIFFSetField (3T)
for information on how to do this.
.PP
\fB%s: Must set "PlanarConfiguration" before writing data\fP.
The organization of data has not be defined before the first write.
See
.IR TIFFSetField (3T)
for information on how to do this.
.PP
\fB%s: No space for tile arrays"\fP.
There was not enough space for the arrays that hold tile
offsets and byte counts.
