<H2>NAME</H2>
TIFFWritedEncodedTile - compress and write a tile of data to an open
<FONT SIZE="-1">TIFF</FONT>
file
<A NAME="lbAC">&nbsp;</A>
<H2>SYNOPSIS</H2>
<B>#include &lt;<A HREF="file:/usr/include/tiffio.h">tiffio.h</A>&gt;</B>
<BR>
<B>tsize_t TIFFWriteEncodedTile(TIFF* tif, ttile_t tile, tdata_t buf, tsize_t size)</B>
<A NAME="lbAD">&nbsp;</A>
<H2>DESCRIPTION</H2>
Compress
<I>size</I>
bytes of raw data from
<I>buf</I>
and
<B>append</B>
the result to the end of the specified tile.
Note that the value of
<I>tile</I>
is a ``raw tile number.''
That is, the caller must take into account whether or not the
data are organized in separate places (<I>PlanarConfiguration</I>=2).
<I>TIFFComputeTile</I>
automatically does this when converting an (x,y,z,sample)
coordinate quadruple to a tile number.
<A NAME="lbAE">&nbsp;</A>
<H2>NOTES</H2>
The library writes encoded data using the native machine byte order.
Correctly implemented
<FONT SIZE="-1">TIFF</FONT>
readers are expected to do any necessary byte-swapping to
correctly process image data with BitsPerSample greater than 8.
<A NAME="lbAF">&nbsp;</A>
<H2>RETURN VALUES</H2>
-1 is returned if an error was encountered.
Otherwise, the value of
<I>size</I>
is returned.
<A NAME="lbAG">&nbsp;</A>
<H2>DIAGNOSTICS</H2>
All error messages are directed to the
<I><A HREF="TIFFError.3t.html">TIFFError</A></I>(3T)
routine.
<P>
<B>%s: File not open for writing</B>.
The file was opened for reading, not writing.
<P>
<B>Can not write tiles to a stripped image</B>.
The image is assumed to be organized in strips because neither of the
<I>TileWidth</I>
or
<I>TileLength</I>
tags have been set with
<I><A HREF="TIFFSetField.3t.html">TIFFSetField</A></I>(3T).
<P>
<B>%s: Must set &quot;ImageWidth&quot; before writing data</B>.
The image's width has not be set before the first write.
See
<I><A HREF="TIFFSetField.3t.html">TIFFSetField</A></I>(3T)
for information on how to do this.
<P>
<B>%s: Must set &quot;PlanarConfiguration&quot; before writing data</B>.
The organization of data has not be defined before the first write.
See
<I><A HREF="TIFFSetField.3t.html">TIFFSetField</A></I>(3T)
for information on how to do this.
<P>
<B>%s: No space for tile arrays&quot;</B>.
There was not enough space for the arrays that hold tile
offsets and byte counts.
